Borrowed Scars (Iruka SI) - Chapter 1 (Patreon)

Author's Note:

Hey, y'all. Bet you weren't expecting an update this quicky knowing my updating tendancies (I dearly hope you became Patron knowing that, thank you for that by the way, very unexpected!) This is going to be a Patreon exclusive story for now - and based on your wonderful opinion I'll continue it or leave it be.

Just to be clear, SIruka is Iruka at his core - he is kind and caring just as he was in the original timeline. This merge hasn't made him edgy or drastically different in personality, just added... perspective and foreknowledge.

This will become public after I write up the next two chapters for you all, then it'll go up on QQ eventually.

Without any further waiting, here is Borrowed Scars (Iruka SI) and its first chapter: Borrowed Burdens.

Borrowed Scars (Iruka SI)

Chapter 1: Borrowed Burdens

The ceiling was wrong.

That was the first coherent thought my brain managed to form through the thick, cottony fog of waking. Rough wooden beams stretched overhead, dark against the lighter wood panels between them. Sunlight, pale and early, slanted in from a window somewhere to my left, painting stripes across the simple blanket covering me. It smelled faintly of dust motes dancing in the light. My apartment – the one I remembered – had a boring, white plaster ceiling and smelled vaguely of stale coffee and maybe instant ramen.

Where... was I?

I pushed myself up, the blanket pooling around my waist. The sheets felt coarse, practical, not the soft cotton I was used to. And my body... it felt wrong. Not injured or sick, just... different. My arms, resting on the blanket, looked tanned, corded with lean muscle I definitely hadn't earned sitting at a desk. I flexed my hand again, tracing the raised lines of calluses on the palm and fingers. These weren't the soft hands of someone whose main workout was typing. These were hands that knew hard work, maybe gripping tools… or weapons? A faint, familiar ache resided in my shoulder, the kind that comes from repetitive strain or an old injury.

A low thrum started behind my eyes, a building pressure that made me wince. Not now. I hated waking up with headaches. I swung my legs over the side of the bed, my bare feet hitting cool wooden floorboards. The room was small, spartan but tidy. A simple desk, a closed wardrobe, a bookshelf filled mostly with scrolls and practical-looking texts. No posters, no computer, no clutter. Definitely not my room.

The thrumming intensified, spiking into a sharp, agonizing pain that felt like my skull was splitting open. I gasped, pressing the heels of my hands against my temples. But it wasn't just pain. It was... images. Sounds. Feelings. Memories, crashing into me like a tidal wave, too fast, too vivid. Not mine. Or were they?

Warmth. Not just a feeling, but a specific memory. Sitting on an engawa, warm wood beneath me, small legs dangling. A woman with gentle brown eyes humming a soft tune beside me, mending a tear in a small shirt. A man with a proud, easy smile sitting opposite, showing me how to make a simple hand seal, his large, calloused fingers guiding my clumsy small ones. "See? Like this, Iruka. Concentrate your chakra..." His voice, deep and kind. Safety. Belonging. Mom. Dad. The memory glowed with a pure, uncomplicated love that made my chest ache. My parents.

Terror. The warmth vanished, replaced by searing heat on my skin, the acrid smell of smoke burning my nostrils. The sky wasn't blue, it was the deep black of midnight. A monstrous roar echoed through the air, shaking the very ground. Buildings collapsing into dust and flame. Chaos. Screams. Someone grabbed my arm – rough hands, urgent. 

"Sorry kid, gotta go! Your parents are fighting, they'll be back!" A shinobi, face grim, pulling me away from the unfolding horror. I twisted, screaming for them, seeing them for just a second – two small figures turning towards the gigantic, nine-tailed shape of hate dominating the skyline. A final, desperate look shared between them, then swallowed by smoke and roaring destruction. No! Come back! The grief hit me then, a physical blow, stealing my breath, leaving a gaping wound that felt like it had happened only yesterday. My parents... gone.

"Wait... who...?" a fragmented thought tried to surface through the pain. "Why am I seeing this?"

Cold. The echoing silence of the small apartment I was given afterwards. The taste of bland rice balls eaten alone at the Academy lunch table, other children whispering behind their hands. "That's him... his parents died..." "The fox..." Their words were sharp little needles. The desperate, hollow ache of loneliness. Look at me! Somebody! The memory of paint, sticky on my hands, grinning wildly as I defaced the Academy building – a childish cry for attention. The fleeting thrill when shinobi finally noticed, chased me down. Then the crushing weight returning when the attention faded, leaving only disapproval and that same, vast emptiness.

"No... stop..." Another weak protest from my own consciousness, overwhelmed.

A Hand. Sitting alone again, this time on a bench near the memorial stone, tracing the newly carved names. A shadow fell over me. I looked up. A boy my age, maybe slightly older, with light hair and a hesitant smile. Mizuki. "Hey," he'd said, offering a dango stick. "You look rough, wanna eat?" That simple act of kindness, the shared treat, the feeling that maybe, just maybe, someone saw me and not just the orphan... It was a lifeline. My friend.

The flood finally subsided, leaving me trembling, gasping for breath on the edge of the unfamiliar bed. The headache eased, leaving a dull, throbbing exhaustion behind it. But the emotions... they swirled inside me, potent and real. Iruka's joy. Iruka's grief. Iruka's loneliness. Iruka's fragile hope. They weren't just memories I'd witnessed; they felt like my experiences now, settled deep in my bones, intertwined with the ghostly recollections of a life that felt suddenly distant and unreal – traffic noise, flashing screens, the smell of rain on concrete.

Two lives. One mind. A merge.

I remember my parents. Their faces, their voices. I remember the attack. The terror, the loss. I remember being alone. The ache of it. I remember Mizuki. His first smile.

My breath hitched again. I pushed myself shakily to my feet, walked towards the dresser. My reflection stared back from the small, clean mirror above it. Familiar brown hair tied back in its signature ponytail, the scar across the bridge of the nose, the kind brown eyes that now held a flicker of something new – confusion, shock, and a dawning, terrifying understanding. This was Iruka Umino's face. My face.

I reached out, touched the kunai pouch lying neatly beside a stack of graded papers. Felt the worn leather, the cool metal of the ring pull. My fingers brushed against the sturdy fabric of the flak jacket hanging nearby. Real. Solid.

Konoha. The name resonated, locking everything into place. The Nine-Tailed Fox attack... twelve years ago. My age matched. Chunin. The rank felt right. Academy Instructor. Yes, the papers, the quiet order of the room...

No. This can't be real. The denial was automatic, instinctive. This is just a crazy dream. I hit my head. Something.

But the memories felt too real. The grief felt too real. The calluses on my hands felt too real.

This is the Naruto world. The thought landed with cold certainty this time, pushing past the denial. And I'm Iruka.

A wave of vertigo hit me, and I gripped the edge of the dresser to steady myself. Iruka. Steady, reliable, kind-hearted Iruka-sensei. The first person to truly see Naruto. The chunin who stood against Mizuki to protect the forbidden scroll, to protect his student...

My eyes widened in the reflection, horror dawning.

Oh god. Naruto.

The name resonated in my whirring mind, pulling my – Iruka's – focus sharp. Naruto Uzumaki. The Kyuubi Jinchuriki. My student. The memories associated with him weren't a smooth progression, more like a tangled knot of reluctance, duty, and slowly dawning empathy.

I remembered seeing his name on the class roster for the first time, years ago now. Uzumaki Naruto. A name whispered with unease by some staff. The child who carried the catastrophe that orphaned me. The memory surfaced: standing outside the Third Hokage's office, my hand halfway raised to knock. The words were a coward's plea forming in my mind: Lord Third, perhaps another instructor would be better suited... But I couldn't do it. Couldn't voice that rejection. Maybe it was the memory of the Hokage's unwavering, grandfatherly gaze when he'd assigned Naruto to me, the implicit trust he'd placed in me. Maybe it was the faint, uncomfortable echo of my own childhood loneliness, a sense that abandoning this loud, disruptive kid would be hypocritical. I'd lowered my hand, turned away, and accepted the assignment with a heavy heart.

The early days were... trying. Naruto was pure chaos in the classroom. Loud, hyperactive, constantly pulling pranks – exploding chalk dust, badly drawn caricatures, failing to do even basic tasks by himself with poorly made dummies. His grasp of basics was abysmal. His Clone Jutsu attempts were legendary failures – pale, lifeless lumps that flopped uselessly to the floor, earning ridicule from classmates and sighs from me. He craved attention, any attention, even negative.

It was exhausting. There were days I felt nothing but frustration. But then... there were moments. Glimpses behind the loud facade. I remember staying late one evening to grade papers, glancing out the window to see Naruto alone in the deserted training yard. He was practicing hand seals, over and over, brow furrowed in intense concentration, trying to make a proper clone. Failing repeatedly. Yet, he didn't stop. He just picked himself up, dusted himself off, and tried again with a stubborn determination that surprised me. Another time, I saw him sitting alone on the swings after class, watching other children run off with their parents, the usual boisterous energy gone, leaving only a stark, profound loneliness in his blue eyes.

That look... it resonated deep within the core of Iruka's memories. I know that feeling.

Slowly, reluctantly, the wall I'd kept up began to crumble. I started seeing less of the 'demon container' and more of the lonely, determined, desperately attention-starved kid underneath. I pushed him harder in class, yes, but I also started offering small words of encouragement when he actually tried, started calling him out for disruptions but also making sure he wasn't completely ignored.

And that led to yesterday. Naruto had actually managed to hold a Transformation Jutsu for a full minute without dropping it prematurely or messing up the details – a minor miracle, frankly. He'd looked so absurdly proud of himself. Maybe it was seeing that flicker of genuine accomplishment, maybe it was just weariness after a long week, but the words slipped out impulsively: "Alright, Naruto, not bad. Keep that focus up. Tell you what... for actually concentrating today, I'll treat you to Ichiraku Ramen tomorrow."

His reaction had been explosive. "Whoa! Really, Iruka-sensei?! You promise?! Ichiraku! Yes!" He'd practically vibrated with excitement, already talking about what flavor he'd get.

Now, standing in my – Iruka's – apartment, the memory hit with full force. That promise. Made casually, perhaps, but received with the absolute gravity only a ramen-obsessed, attention-starved kid could muster. This fragile bridge of trust I was building with him... it felt incredibly important, now more than ever with this strange new awareness swirling in my head. He trusted my word. Forgetting, or backing out... it wouldn't just be mean. It would be reinforcing every fear he had about people not really caring.

My eyes darted to the clock on the wall. Still early, the sun barely above the neighboring rooftops. Okay, good. A wave of relief washed over me. The promise was for later today, likely evening, after any chores or training I – or he – might do. Plenty of time. But the importance remained, settling like a weight in my gut. Don't forget. Don't mess this up. It felt like the first concrete task in this new, bewildering reality. Keep the promise to Naruto.

With the immediate panic averted, another name surfaced, unbidden, casting a different kind of chill over the quiet morning air.

Mizuki. The name echoed differently now. The warm memory of childhood friendship – the shared dango, the easy laughter, the feeling of finally having someone understand – felt tainted, like finding mold on old bread. It looked okay on the surface, but something felt fundamentally wrong underneath.

Memories from my other life, the ones from that world without chakra or shinobi, whispered warnings. Mizuki, the traitor. Mizuki, manipulating Naruto into stealing the Forbidden Scroll. Mizuki, trying to kill me – Iruka – when I interfered. That knowledge overlaid Iruka's own recollections, forcing a painful re-examination.

I leaned against the cool wood of the dresser, closing my eyes, deliberately sifting through the past interactions stored in Iruka's mind, viewing them now with a heavy dose of suspicion.

Think back. After graduating the Academy, top of our class, both of us. I’d been eager, buzzing with energy. "Let's go drill some extra katas, Mizuki! We need to be sharp!" I remembered saying it, practically vibrating with readiness.

Mizuki had laughed, slinging a friendly arm around my shoulders. "Easy there, Iruka! We just graduated! Time to celebrate, relax a little. Come on, I know a place with great Mitarashi dango." His smile was wide, open, convincing. And I’d gone along easily, the lure of friendship and sweets overcoming my momentary burst of ambition. At the time, it felt like camaraderie. Now? It felt... like deflection. A gentle nudge away from immediate self-improvement.

Another memory surfaced. A few years later. Considering applying for a specific Chunin field rotation, one known for being challenging but offering valuable experience. I'd mentioned it to Mizuki over lunch. He’d frowned, looking genuinely concerned. "That rotation? Didn't you hear? Three shinobi got badly injured on a similar assignment just last month. Ambush patrol. Nasty business. You sure you want that kind of risk right now, Iruka?" He’d recounted the story with grim detail. It sounded like friendly concern, a well-meaning warning. I’d hesitated, second-guessed myself, and ultimately applied for a less demanding internal assignment instead. Now, the memory felt... pointedly discouraging. Was the story even accurate? Or just a convenient way to steer me away from something that might have pushed my skills, made me stand out?

And then... the mission. The one under Kakashi-senpai's command. The injury. It wasn't crippling, maybe not career-ending if I'd truly pushed rehabilitation, but it had hurt. Physically, yes, but the blow to my confidence had been worse. Laid up in the hospital wing, feeling discouraged, the path forward seeming uncertain. And Mizuki had been there, a constant, sympathetic presence.

"Fieldwork is brutal, Iruka," he'd said softly one afternoon, his voice low and full of understanding. "Maybe... maybe your real strength isn't out there risking your neck." He'd gestured vaguely. "Your heart, your patience... you connect with people. Especially kids. Think of the good you could do at the Academy. Passing on the Will of Fire, guiding the next generation. Isn't that just as important? Maybe even more so?"

His words had landed like a balm on the injured, uncertain Iruka. It felt like validation, like finding a noble purpose when the previous one seemed fraught with pain and potential failure. The path to becoming an Academy instructor had felt like my choice, born from genuine reflection on my strengths and weaknesses after the injury.

But now... looking back through this strange, combined lens... was it entirely my idea? Or had Mizuki subtly, kindly, persistently guided me here? To this role? Safe. Respected amongst educators. But ultimately... contained? Stuck at Chunin, teaching fundamentals, while he... what? What were his quiet ambitions?

A cold knot tightened in my stomach. Knowledge from my other life suggested the motive: jealousy. A deep-seated resentment simmering beneath the easygoing, friendly facade. Had he been quietly pruning my potential all along, keeping me comfortably mediocre while he nursed his own grievances and plots?

He was my friend, a part of Iruka's core protested, the warmth of shared history warring with the cold suspicion. He wouldn't... would he?

But the pattern, viewed with this new, unwelcome clarity, was hard to ignore. The convenient advice always steering towards safety, towards teaching, away from risk and advancement. The constant underpinning of 'your strength lies in kindness, not combat'.

I pushed myself away from the dresser, pacing the small confines of the room. Okay. Assume the worst for now. Assume Mizuki is not the friend Iruka believed him to be. Assume he's manipulating things, driven by jealousy, already walking the path that leads to betrayal two years from now.

What does that mean for me, today?

It means the trust is broken, even if he doesn't know it. I have to pretend. Act normal. Keep up the appearance of friendship. He's a colleague, we work together daily at the Academy. Pulling away suddenly would raise alarms I can't afford. But I need to watch him. Closely. Observe his interactions, his words. Especially around Naruto.

And it means... this comfortable plateau Iruka settled onto has to end. Immediately. Whatever potential Mizuki might have gently encouraged me to set aside needs to be rediscovered and honed. Teaching is important. Vital. I believe that. But if I'm going to protect these students – protect Naruto – from dangers I know are coming... dangers that might include the man smiling politely across the staff room... then I need to be much, much stronger than I am right now.

The realization wasn't comforting. It carried the heavy weight of responsibility and the cold thrill of fear. But it was also... clarifying. It gave me a direction in this bewildering new existence.

My gaze drifted back to the green flak jacket hanging by the door. The path forward suddenly seemed brutally simple, stripped down to essentials. Train. Get stronger. Watch Mizuki. Protect my students. Survive.

First step? Take stock. Figure out exactly what tools I have in the toolbox right now. A thorough self-assessment was needed.

The decision settled heavily in my chest, a grim sort of determination solidifying amidst the confusion. I couldn't just sit here, reeling from memory floods and unsettling realizations about Mizuki. Knowing what I knew, feeling this fragile connection to Naruto... inaction wasn't an option. If I was going to make any difference, if I was going to survive, I needed to know my starting point. Honestly. Brutally.

It was Sunday. No Academy today. The timing felt... fortunate. A whole day to process, and now, to act.

My eyes scanned the room. Practical training clothes were folded neatly in the wardrobe – simple dark pants, a durable long-sleeved shirt. Not the official Chunin vest, just gear meant for function, not display. I changed quickly, the familiar feel of the fabric somehow grounding. Next, the small pouch of standard ninja tools – kunai, shuriken, some wire, explosive tags. Basic, essential. I strapped it securely to my thigh.

Where to go? I needed somewhere relatively secluded. Somewhere I wouldn't be easily observed, especially if my performance was... lacking. Training Ground 3 came to mind – average terrain, usually quiet on weekends unless a team had specifically booked it. Or maybe that clearing in the woods bordering the village? Iruka used to go there sometimes as a kid, seeking solitude after his parents... My parents. The thought still jarred. Yes, the clearing would be better. More privacy.

Leaving the small apartment, locking the door behind me with a key that felt strangely familiar in my hand, I stepped out into the Konoha morning. The village was waking up – sounds of vendors setting up stalls, muted chatter, the distant clang of a blacksmith's hammer. It felt surreal, like stepping onto a meticulously crafted movie set, yet the solidity of the ground beneath my worn sandals, the scent of cooking fires and damp earth, the way the sunlight warmed my skin... it was undeniably real.

Pushing down the lingering sense of disorientation, I set off at a steady jog towards the village outskirts, following paths ingrained in Iruka's muscle memory. The route wound through residential areas, past small shops, eventually leading to less-trafficked paths near the perimeter wall. The exercise felt good, loosening muscles tight with tension.

Soon, the village sounds faded, replaced by the rustle of leaves and birdsong. I found the clearing easily – a familiar space, dappled sunlight filtering through the canopy overhead. It felt peaceful, isolated. Perfect.

Alright. Time to see what this body could actually do.

I started with the simplest, most fundamental thing: stamina. Taking a deep breath, I began running laps around the perimeter of the clearing. The initial pace felt comfortable, easy even. Iruka hadn't been completely sedentary; teaching required a certain level of fitness, demonstrating techniques, moving around the classroom and training yards. But as the laps piled up, a familiar burn started in my lungs, my breathing growing heavier sooner than I liked. I pushed on, forcing myself to maintain the pace, but the drop-off was undeniable. Years away from regular, intense field conditioning had clearly taken their toll. Okay, I thought, finally slowing to a walk, hands on my knees, catching my breath. Endurance isn't terrible, but it's definitely slipped. Not built for a prolonged fight right now. Needs consistent work. Priority one.

Next, Taijutsu. I moved to the center of the clearing and cycled through the basic Academy katas – stances, blocks, strikes, evasive footwork. Here, the movements flowed effortlessly. Crisp, precise, textbook-perfect. Years of drilling these fundamentals with students had ingrained them deep. Alright, the fundamentals are rock solid, my inner voice confirmed. Daily teaching keeps these sharp.

Then I shifted, transitioning into more complex Chunin-level solo sequences Iruka knew – patterns involving quick dodges followed by counter-strikes, forms incorporating drawing and retracting a kunai smoothly, momentum-based evasions designed to create openings. I knew the sequences. The muscle memory was there... mostly. But there was a hesitation, a slight stiffness that hadn't been present in the basics. The flow wasn't quite right. I completed the forms successfully, but they felt... rusty. Not incompetent, but lacking the practiced ease, the split-second reaction time needed for actual combat. There it is, I thought, frowning. I know these moves, but they feel sluggish. Under pressure, that tiny delay could get me killed. Need to drill these until they flow like breathing again. Can't practice counters or grappling alone, though. Need sparring for that... later.

Time for Ninjutsu. I stood still, focusing. First, the Academy Three. A quick sequence of hand seals: Transformation Jutsu. A puff of smoke, and I was near a small pond, I went to check my reflection and I looked at a perfect replica of the Third Hokage – wrinkles, robes, everything. Dropped it. Clone Jutsu. Seals flashed, another puff, and three solid, identical copies of myself stood beside me. They held form, no flickering. Dismissed them. Substitution Jutsu. Focused on a nearby log, performed the seals, and in an instant, I was standing where the log was, leaving behind only a puff of smoke where I'd been. Academy basics are perfect, I noted with some satisfaction. No issues there.

Chakra assessment next. I focused inward, trying to gauge my reserves. It felt... adequate? Like a standard Chunin pool, maybe a little under peak condition from less demanding use. Control felt fine for these simple techniques. Capacity feels... okay, but not impressive. Wonder how efficient I am with it? Feels like I used a bit more juice than strictly necessary for those clones.

Now, for actual combat jutsu, the ones Iruka knew beyond the basics. Fire Release. I went through the seals – Horse, Tiger. "Fire Release: Phoenix Sage Fire Technique!" Taking a controlled breath, I expelled chakra, spitting out a volley of small fireballs. They flew towards a designated patch of earth, kicking up dirt on impact. They were controlled, hit the target area, but they seemed... small. Lacking intense heat or concussive force. Functional C-rank, I assessed. But could be hotter, faster, more focused.

Water Release next. Seals: Snake, Boar, Ram, Hare, Boar. "Water Release: Wild Water Wave!" Slamming my hand on the ground, I channeled chakra. A surge of water erupted, flowing outwards, carving a shallow trench in the dirt before soaking into the ground. Decent force, respectable volume for the rank. Another basic C-rank, I thought. Serviceable, but not overwhelming. Range and pressure could probably be improved. I mentally noted the Yin Release affinity mentioned in Iruka's memories, but recalled no specific offensive or supplementary Yin jutsu he actively practiced.

Barrier Ninjutsu. I focused on the String Light Formation, a containment technique. I knelt, forming the necessary hand seals before slamming my palm onto the earth. Chakra spread outwards, etching faint, glowing lines across the ground in a circular pattern around me. The formation stabilized, holding its shape. Okay, the jutsu works, I assessed. But the seals felt... slow. Forming it wasn't as instantaneous as I remember it being. Need to practice the sequence speed. I couldn't test the immobilization effect without someone stepping inside, but the stable pattern suggested the core function was likely intact. Still a potentially useful tool for capture or defense, but need to be faster on the deployment.

Genjutsu. I mentally reviewed the illusions Iruka knew. The primary one was the Demonic Illusion: Hell Viewing Technique. I recalled using it effectively on missions years ago, against bandits or rogue shinobi – showing them their deepest fears to break their will or create an opening. The theory was solid, the hand seals remembered. But casting it under pressure? Quickly, subtly, holding it against a resisting mind? That felt like a distant skill, severely dulled by years spent focused on Academy instruction rather than active combat. Practical application is very rusty. A definite weak point to be wary of.

Echolocation. This was different. Not a standard Konoha technique. I closed my eyes, concentrating, and sent out a specific, low-frequency pulse of chakra, feeling it radiate outwards. The returning 'echoes' painted a mental image of the clearing – the precise location of trees, the shape of the large rock, even the slight depression near the edge where water pooled after rain. This technique... it came from an incomplete scroll I’d found amongst my parents' meager belongings after their deaths. Just fragments, notes on using chakra for sensory enhancement. It had taken months of obsessive work, pouring over the damaged text, trial and error, to reconstruct and master it. It felt personal, a legacy of sorts. The sonar sense is sharp, I noted with grim satisfaction. A unique advantage. Keep it honed.

Finally, weaponry. Shurikenjutsu. I drew a handful of kunai and shuriken. Picked targets – knots on tree trunks, specific leaves. Threw them in quick succession. Thwack, thwack, thwack. Most hit dead center or very close. The groups were tight. Teaching pays off, I acknowledged. Accuracy is good. Still got the instructor's eye. Now for the trickier skill – the ricochet. I spotted a thick tree trunk and mentally marked a spot on another tree behind it, out of direct line of sight. Calculated the angles. Threw a kunai hard against the first trunk – it bounced off at the predicted angle, sinking satisfyingly into the hidden target zone. I repeated it twice more, both successful. Good. The deflection skill is still sharp. A good trick to keep polished.

I stood there in the dappled sunlight of the clearing, catching my breath, the exertion settling into a dull ache in muscles that hadn't been pushed like this in a long time. The sweat cooling on my skin felt real. The scent of turned earth and pine needles was sharp in my nostrils. My assessment was done. Time to face the results.

Okay. I mentally ticked off the points. Fundamentals are excellent. Academy Taijutsu basics, the standard three Ninjutsu, Shurikenjutsu accuracy, even the ricochet technique – all sharp, reliable. Teaching drilled those constantly. That was the good news.

The bad news? Everything else. Stamina was subpar for serious fieldwork. Advanced solo Taijutsu katas were rusty, the muscle memory present but sluggish. Actual combat application? Untested in years, and grappling or counters were impossible to judge without a partner. My offensive Ninjutsu was limited to two functional, but decidedly unimpressive, C-rank techniques – Phoenix Fire and Wild Water Wave. The potential of Fire and Water affinities felt largely untapped. The String Light Formation barrier jutsu worked, but deploying it felt slow. Practical Genjutsu was a definite weak point, barely functional beyond theory and recognition. My chakra reserves felt average, and efficiency was probably lacking. The Echolocation technique was a unique bright spot, a personal skill that was still sharp.

Overall conclusion? I sighed, rubbing my neck. I was a highly competent Chunin instructor. My skills were perfectly tailored for teaching fundamentals and handling minor threats. But for Jonin-level dangers? For sustained combat against determined opponents? For dealing with a potentially treacherous fellow Chunin like Mizuki? I was dangerously unprepared. The potential for becoming a Jonin or Anbu felt like a distant, hypothetical thing, buried under years of comfortable routine and, perhaps, Mizuki's subtle discouragement.

Right. The grim determination from earlier returned. This stagnation ends now.

A rough plan began forming in my mind. Stamina first. Daily runs, maybe early mornings before the Academy. Easy enough to incorporate. I looked down at my hands. Advanced Taijutsu katas need drilling until they're instinctive again. Afternoon sessions, after class. I frowned. Need sparring partners eventually, but that's tricky. Can't just ask anyone without raising questions.

Ninjutsu... practice Phoenix Fire and Wild Water Wave. Increase power, speed, efficiency. But I need more jutsu. Scrolls. Where can I access C or even B-rank scrolls for Fire and Water without drawing too much attention? The main library requires clearance for higher ranks... Maybe I could leverage my instructor status somehow? Or perhaps there were older training manuals stored somewhere... Barrier Ninjutsu – drill the hand seals for speed.

Genjutsu... I hesitated. Focus on recognition and breaking for now. My application is too weak to be reliable yet. Echolocation needed regular practice too, just to keep it sharp.

It was a lot. It felt overwhelming, trying to fit serious training around the demanding schedule of an Academy teacher. Have to be smart about it. Consistent effort over time. And subtle. Can't let Mizuki, or anyone else, see me suddenly training like a madman.

My thoughts drifted to the Academy. Monday morning. Facing the kids. Facing Mizuki. Acting normal. Pretending everything was the same, while underneath, everything had changed. Keeping a closer eye on Naruto, making sure Mizuki wasn't... influencing him negatively. The rumors from my other life about crippling Naruto's potential felt suddenly very relevant, a sickening possibility.

Naruto...

My train of thought screeched to a halt. A sudden, cold jolt went through me, completely unrelated to the training fatigue.

Naruto. Yesterday. The Transformation practice. The memory flashed bright and clear: Naruto's beaming face, my impulsive words. "I'll treat you to Ichiraku Ramen tomorrow."

Tomorrow. Which was today.

"Oh, shit!" The words slipped out loud this time, echoing slightly in the quiet clearing.

My carefully constructed training plans evaporated like mist. The ramen promise. Evening, I'd mentally noted earlier. But the importance of it hit me with full force again. This wasn't just noodles. This was about trust. About showing Naruto that someone's word meant something, that someone showed up. Especially after... well, after everything he dealt with daily. Flaking wasn't an option.

Right. New priority. Head back. Clean up. Get some food in me – proper fuel, not just adrenaline and dawning panic. Maybe review some lesson plans for tomorrow, act normal. And then, this evening, be at Ichiraku. On time. Wallet ready.

I quickly gathered the few kunai I'd left sticking in trees, wiped the sweat from my brow with the back of my hand, and turned back towards the village, moving with a new sense of immediate purpose that had nothing to do with combat training. First, survive the day. Then, survive the ramen bill. Then, figure out how to survive everything else.

The rest of the day passed in a strange blur. Back in my apartment – Iruka's apartment – I went through the motions. Showered, changed into clean, casual clothes. Ate a simple lunch, the food tasting slightly unfamiliar despite the memories telling me it was a regular meal. I even sat down at the small desk and tried to review the lesson plan for tomorrow's Academy class – something about basic chakra control exercises. The characters on the scroll seemed to swim before my eyes. My mind kept replaying the morning's revelations, the training assessment, the chilling realization about Mizuki. And underneath it all, the quiet, insistent reminder: Ichiraku. Evening. Don't be late.

As evening approached, casting long shadows across Konoha, I felt a knot of nervous energy tighten in my stomach. It was ridiculous. It was just ramen with a student. An unusually loud and troublesome student, yes, but still. Yet, it felt… significant. The first real test of navigating this new reality, of fulfilling the responsibilities I’d inherited alongside Iruka’s memories and scar.

I had visited Ichiraku's Ramen before, a couple times actually, so I knew the way.

I arrived at Ichiraku Ramen a few minutes early. The familiar stand glowed warmly under the evening sky, steam billowing invitingly from behind the counter flap, carrying the rich aroma of pork broth and noodles. Teuchi, the owner, gave me a friendly nod from his position over the boiling pots. His daughter Ayame offered a welcoming smile as she wiped down the counter.

"Evening, Iruka-sensei!" she greeted cheerfully.

"Evening, Ayame-san, Teuchi-san," I replied, trying to sound normal, casual. I took a seat at the counter, my eyes scanning the street. No sign of blond spikes yet. Okay. Good. Not late.

I’d barely settled onto the stool when a familiar yellow-orange blur came tearing around the corner, practically vibrating with energy.

"Iruka-sensei! You're here! You actually came!" Naruto skidded to a halt in front of the stand, beaming, blue eyes wide with excitement. There was a faint undertone of surprise in his voice, as if he hadn’t really believed I’d show up until he saw me sitting there. That little hitch of disbelief sent a pang through me.

"Of course, I came, Naruto," I said, keeping my voice level, maybe a touch warmer than usual. "I promised, didn't I?"

He scrambled onto the stool beside me, bouncing slightly. "Yeah! Ramen! I'm starving! Old Man Teuchi, gimme the biggest bowl of miso char siu you got! Extra pork!"

Teuchi chuckled. "Coming right up, Naruto. And for you, Iruka-sensei? The usual?"

The usual. Iruka's memories supplied it – a simple shoyu ramen. "Yes, please, Teuchi-san." My hand instinctively drifted towards my wallet, feeling its depressingly light weight. Extra pork… this is going to hurt.

As Teuchi started assembling the bowls, Naruto turned to me, already talking a mile a minute. "So, so? When you're not teaching us boring stuff at the Academy, do you get to practice awesome secret ninja techniques? Like, BOOM! Pow!" He jabbed the air enthusiastically. "Or maybe some super cool jutsu? Like making water dragons? Or giant fireballs?" He made wildly inaccurate, but energetic, hand gestures.

A small smile touched my lips. It felt surprisingly genuine. "Secret techniques are usually secret for a reason, Naruto," I said, reaching out instinctively and ruffling his spiky hair. He squawked in protest but didn't pull away. "And even Jonin spend most of their time practicing the basics. Making sure everything stays sharp."

"Awww, basics!" He slumped dramatically against the counter. "Basics are boring! Why can't we learn the cool stuff? Something like the Flying Thunder God technique! That sounds awesome!" His eyes shone with admiration for the Fourth Hokage's legendary jutsu.

My breath caught slightly. Flying Thunder God. The pinnacle of space-time ninjutsu, far beyond anything I—or most shinobi—could ever dream of mastering. "Paying attention during your history lectures, I see?" I remarked, a little surprised he remembered the name. "And even Jonin spend most of their time practicing the basics," I repeated gently, firmly. "The cool stuff comes later, Naruto. Only after you master the fundamentals. Strong basics are the foundation for everything else. You can't build a sturdy house on shaky ground, right?"

He puffed out his cheeks, clearly unconvinced but perhaps slightly placated by the acknowledgment, and subsided as Teuchi placed enormous, steaming bowls of ramen in front of us. "Thanks, Old Man!" Naruto chirped, instantly forgetting the conversation and grabbing his chopsticks. "Itadakimasu!"

He dug in with gusto, slurping noodles noisily, cheeks puffed out like a chipmunk. Watching him, my earlier resolve felt distant. This kid… he was just a kid. A lonely, loud, desperate-for-acknowledgment kid who happened to carry an immense burden he didn't even understand. The weight of my foreknowledge felt immense. All the pain waiting for him – Mizuki's betrayal, the Chuunin exams, Gaara, Sasuke leaving, Akatsuki, Pain… It was too much.

My job, I realized, wasn't just about getting stronger myself. It was about helping him get stronger. Not just teaching him jutsu, but building that foundation I just talked about. Resilience. Trust. Giving him something solid to stand on before the storms hit.

And not just Naruto. My thoughts drifted to the rest of the class, the faces I saw every day. Ino and Sakura, both sharp, letting their potential get tangled up in a rivalry over Sasuke. Could I arrange something? Maybe ask a retired, no-nonsense kunoichi to come talk to them, really lay out the dangers they'd face, shake them out of that fangirl mentality? Sasuke... I honestly didn't know what I could do there, not yet. The weight of his family's fate was immense. But I had to try something. Then there were Shikamaru, Choji, and Shino – smart, capable, mostly needing guidance and real challenges. Hinata, quiet and hesitant... maybe creating small, safe opportunities for her to build confidence would help her bloom earlier. Kiba, bless his energetic heart, needed his ego checked before it led him into trouble. Perhaps a 'reality check' day for the whole class? Bringing in some Genin or Chunin, fresh from the field, to share unvarnished experiences... It was a thought. They all needed more than katas and jutsu theory. They needed to be prepared. They needed to be aware of the life they were gonna step into.

"Hey, Iruka-sensei," Naruto mumbled around a mouthful of noodles, oblivious to my internal turmoil. "You gonna eat yours? Or just stare at it?"

I blinked, pulled back to the present. "Right. Sorry." I picked up my own chopsticks. The simple act of eating ramen with Naruto, listening to him chatter about his day (mostly complaints about other kids and boasts about pranks I probably didn't want to know the details of), felt… normal. A small island of normalcy in the surreal landscape of my new life.

But looking into his bright, trusting eyes, I felt the weight settle again. This was just the beginning. For both of us. For all of us.
