Chapter: Rabbit's Kit

Usagiyama Agency

The sound of flesh hitting high-density padding echoed like a gunshot through the emptiness of the Usagiyama Agency’s private gym.

"Too slow!"

The shout was followed immediately by a blur of white hair and tanned muscle. Naruto Uzumaki saw the heel coming—Mirko’s signature Luna Arc—but his body was already moving. He didn't block; blocking Rumi Usagiyama was a good way to get your forearms shattered. Instead, he dropped his center of gravity, the floor cracking slightly under his bare feet, and surged forward.

"Gotcha," Naruto grinned, his blue eyes flashing with a slit pupil.

He didn't have Chakra anymore. That energy had died with his old world. But he had something else. A Quirk called Nine-Tailed Dynamo. It wasn't just super strength; it was a reactor. A golden, bubbling shroud of kinetic energy that boosted his sensory perception and durability to god-like tiers.

He ducked under the lethal kick, the wind pressure messing up his blonde hair, and slammed his shoulder into her midsection.

It was like hitting a brick wall reinforced with titanium.

"Hah!" Rumi grunted, the impact actually pushing her back a foot. She flipped backward, landing in a crouch, her rabbit ears twitching with predatory excitement. She was sweating, her white leotard clinging to her absurdly sculpted curves, a feral grin stretching across her face. "Finally putting some weight behind it, Kit!"

Naruto straightened up, wiping a trail of blood from his lip. Being Mirko’s apprentice wasn't an internship; it was survival training. Since waking up in this world, orphaned and confused, only to be scouted by the Number 5 Hero during the Sports Festival, his life had been a blur of pain and adrenaline.

"You told me to stop holding back," Naruto said, his voice dropping an octave as the golden energy flickered around his skin like foxfire. "I'm just listening to my Master."

Rumi’s red eyes narrowed, scanning him. She liked what she saw. When she had picked him, he was a rough diamond—wild, loud, unrefined. Now, in his third year at U.A., acting as her sidekick, he was a weapon. He was built thick, corded with muscle that didn't just look good; it functioned.

"Don't get cocky," she scoffed, though the heat in her gaze betrayed her. She cracked her knuckles. "You managed to push me back. Once. Now, let’s see if you can last the next ten minutes without passing out."

"I have the stamina of a beast, Rumi. You know that."

The air in the room shifted. It wasn't just combat tension anymore. It was something heavier. The pheromones of high-level predators circling each other.

"Less talk," she commanded, launching herself off the ground with enough force to crater the concrete. "More fighting!"

Fast Forward

Fukuoka District

The patrol that evening was supposed to be quiet. It never was.

They were in the Fukuoka district, hopping across rooftops. The night air was cool, but Naruto felt hot. His Quirk ran at a high temperature, a constant hum of power beneath his skin. He watched Rumi ahead of him. She moved with an efficiency that was beautiful to watch—explosive power contained in a compact, feminine frame.

"Movement at three o'clock," Naruto said into his comms, his enhanced hearing picking up the scuff of boots on gravel three blocks over. "Heavy. Sounds like... metal dragging?"

"Villains?" Rumi asked, pausing on a water tower.

"Yeah. And they smell like ozone."

"Electric types," Rumi grinned, turning to look at him. The moonlight hit her face, illuminating the scar on her arm and the wildness in her eyes. "My favorite. Let’s go break some bones."

They descended into the alleyway like lightning bolts.

It was a weapons deal. Typical yakuza remnants trying to move quirk-enhancing gear. There were ten of them, all hulking brutes with heteromorphic quirks—spikes, armor plating, and one guy whose arms were literal tesla coils.

"The Rabbit Hero!" one of them screamed.

"And the Fox!" another yelled.

"Smash them!"

The thug with the tesla arms unleashed a torrent of blue lightning. It scorched the walls, aiming straight for Rumi in mid-air. She couldn't dodge in freefall.

She doesn’t have to, Naruto thought.

He flashed. His Quirk exploded outward, forming a golden claw of energy that swatted the lightning aside. He landed in front of her, the concrete shattering.

"Go!" Naruto roared.

Rumi used his shoulder as a launchpad. "Luna Fall!"

She came down like a meteor, her heel driving the electric villain into the pavement with a sickening crunch. The shockwave knocked three other guys off their feet.

Naruto didn't wait. He spun, channeling the rotational energy he used to call Rasengan—now just a dense sphere of pressurized air and kinetic force—and shoved it into the gut of an armored thug. The villain went flying, crashing through a dumpster.

It was a dance they had perfected over months. Rumi was the spear; Naruto was the shield that could also hit like a truck.

But then, the unexpected happened.

The leader, a villain hiding in the back, stepped forward. He didn't look like much, but he pointed a finger at Rumi, who was recovering from her kick.

"Gravity Well," the villain muttered.

Rumi froze. The air around her turned purple. She was pinned, forced to her knees by crushing weight. "What the hell... I can't move!"

"Die, Hero!" The villain pulled a gun—a high-caliber anti-quirk rifle.

Naruto saw it in slow motion. The memories of his past life—of war, of losing people—flashed before him. Not again.

He didn't think. He didn't strategize. He just burned.

"NO!"

Naruto tapped into the deepest reserve of his Quirk—the part that felt like an angry, ancient fox. A red hue bled into his golden aura. He moved so fast he broke the sound barrier in a confined alleyway.

BANG.

The bullet fired.

Naruto caught it.

He stood in front of Rumi, his hand smoking, the flattened slug falling from his palm. His skin was scorched, regenerating instantly thanks to his vitality. He looked at the villain, his eyes now blood-red with a vertical slit.

"You," Naruto growled, his voice vibrating the glass in the windows above. "Are dead."

He vanished.

A split second later, the villain was embedded in the brick wall, unconscious, with Naruto’s fist imprinted in the masonry next to his head. The gravity field dissipated.

Rumi stood up, dusting off her knees. She looked at the unconscious bodies, then at Naruto. He was panting, the red fading back to gold, then to normal. He looked back at her, checking for injuries.

"You okay, Rumi?"

She walked over to him, her hips swaying, her eyes dark. She grabbed the collar of his hero suit—an orange and black tactical vest—and yanked him down to her level.

"You caught a bullet," she whispered, her breath hot against his face.

"It was anti-quirk rounds. If it hit you..."

"You caught a damn bullet, Kit." She licked her lips. The adrenaline was rolling off her in waves. "That was... insanely hot."

Naruto gulped. The look in her eyes wasn't just pride. It was hunger.

"Let’s wrap this up," she said, her voice husky. "We need to debrief. In my office."

Fast Forward

Usagiyama Agency

The Usagiyama Agency was quiet. The sidekicks had gone home. It was just the two of them in the penthouse office, overlooking the Fukuoka skyline.

Naruto was sitting on the edge of Rumi's mahogany desk, an ice pack on his hand. It had already healed, but Rumi insisted. She was pacing the room, still in her hero costume, though she had kicked off her iron-soled boots.

"You're reckless," she said, stopping in front of him.

"I'm effective," Naruto countered. "Besides, you hate safe fighters."

"True." She stepped between his spread legs, placing her hands on his thighs. Her palms were calloused, warm, and strong. "But you scared me for a second. I thought you were going to rip that guy's head off."

"Would you have minded?"

"No." She smirked. "I like it when you get feral."

The air conditioner hummed, but the room felt stiflingly hot. Naruto looked up at her. Rumi Usagiyama was a goddess of war. Strong thighs, a toned stomach exposed by her leotard, and a chest that defied gravity. But it was her attitude—the sheer, unadulterated confidence—that drove him crazy.

"You're staring," she teased, trailing a finger up his face, tracing the whisker marks on his cheeks.

"Hard not to," Naruto admitted. "You look... incredible tonight."

Rumi chuckled, a low, throaty sound. "You've been wanting to do this for months, haven't you? Ever since you walked into my gym."

All façades had vanished at this point. Rumi realized that Naruto had been viewing her with a more suggestive interest for quite a while, but she brushed it off as a mere childhood crush. However, as he matured into a hero, she found herself drawn to him, particularly now that he had turned eighteen.

"Years," Naruto corrected. "Since the Sports Festival."

"Good answer."

She leaned in, her nose brushing against his. "So? Are you going to make a move, or do I have to kick you again?"

Naruto didn't hesitate this time. He grabbed her waist, his hands spanning the muscular curve, and pulled her flush against him. He captured her lips in a searing kiss.

It wasn't gentle. There was nothing gentle about Mirko. She kissed like she fought—with intensity and dominance. Her tongue invaded his mouth, tasting him, claiming him. She bit his lower lip, hard enough to draw a tiny bead of blood, then soothed it with a swipe of her tongue.

Naruto groaned, the vibration rumbling in his chest. He slid his hands down to her hips, digging his fingers into the firm flesh of her glutes, lifting her up.

Rumi wrapped her legs around his waist instantly, her powerful thighs locking him in place. "To the couch," she ordered against his lips. "Now."

Naruto stood up, carrying her effortlessly, and walked over to the sprawling leather couch in the corner of the office. He sat down, keeping her straddling his lap.

"You're in charge on the street, Rumi," Naruto murmured, kissing down the column of her neck, finding the sensitive spot right below her ear. "But who's in charge here?"

Rumi threw her head back, gasping as he bit down on her neck. "Don't get ahead of yourself, rookie. I'm always top dog."

She pulled back, her red eyes burning. She reached for the zipper of her leotard and with a slow, deliberate pull, the fabric parted.

Lemon Scene Ahead

The white fabric fell away, revealing her breasts. They were perfect—full, heavy, and flushed with the heat of the fight. Her nipples were hard peaks, dark against her tan skin.

Naruto’s breath hitched. He had imagined this, sure, but the reality was overwhelming. The scent of her—sweat, ozone, and vanilla—filled his senses.

"I love it," Naruto growled.

He buried his face in her cleavage, his tongue laving over the soft skin, moving to tease one hardened nipple. Rumi hissed, her fingers tangling in his blonde hair, gripping tight.

"Harder," she demanded. "Don't treat me like glass."

Naruto obeyed. He sucked harder, his hand coming up to knead her other breast, squeezing the firm weight. Rumi moaned loudly, the sound echoing in the empty office. She began to grind her hips against his, the friction through his tactical pants nearly sending him over the edge right there.

"My turn," she panted.

She pushed him back against the couch cushions. Her hands went to his belt, her fingers deft and quick. She unbuckled him, shoved his pants and boxers down, and freed him.

Naruto sprang free, thick and throbbing. Rumi’s eyes widened slightly, a smirk playing on her lips.

"Well," she purred, wrapping her hand around him. "Looks like the rumors about stamina quirks are true. You’re... cock is huge."

She didn't waste time with foreplay. She was impatient, fueled by the lingering adrenaline of the battle. She lifted herself up on her knees, positioning herself over him. She hooked her thumbs into the crotch of her leotard and pulled the fabric aside.

She was soaking wet.

"Watch me," she commanded.

Slowly, agonizingly, she lowered herself onto him.

"Oh, god," Naruto groaned, his head falling back against the leather. She was so tight, her muscles clamping down on him like a vice. The sensation was intense, burning and pleasurable.

Rumi gasped as she took the full length of him, her nails digging into his shoulders. When she was fully seated, she paused, her forehead resting against his, both of them panting.

"You fit," she whispered, a rare note of softness in her voice, before the feral grin returned. "Now, hold on."

She began to move.

It wasn't a gentle rock. It was a piston-like rhythm. Rumi used her incredible leg strength to bounce on him, controlling the depth and the pace. Every time she came down, she hit the perfect spot inside her, eliciting sharp cries of pleasure.

"Rumi..." Naruto reached up, grabbing her hips to help her rhythm, to snap his hips upward to meet her.

"Call me Mirko," she gasped, slapping his chest lightly. "When we're like this... I'm your woman."

"Mirko!"

The visual was insane. The Number 5 Hero, the strongest woman he knew, riding him in her office, her rabbit ears twitching with every thrust, her face contorted in bliss.

Naruto’s endurance kicked in. Where most men would have finished in minutes, Naruto was just getting started. He gritted his teeth, his Quirk flaring slightly, sending a wave of golden energy through his veins.

"You're not... quitting yet... are you?" Rumi panted, sweat dripping from her chin onto his chest.

"I told you," Naruto growled, sitting up to kiss her forcefully, his tongue dueling with hers. "I have the stamina of a beast."

He flipped their positions.

With a surge of strength, he rolled them over, pinning Rumi into the leather couch. Now he was on top. Her legs instantly wrapped around his back, her ankles locking.

"Show me!" she challenged.

Naruto drove into her, hard and fast. The slap of skin against skin filled the room. Rumi cried out, her head thrashing from side to side, her hands clawing at his back, leaving red welts that healed seconds later.

He pounded into her with the relentless rhythm of a jackhammer. He hit deep inside her with every thrust, making her toes curl, making the tough-as-nails hero scream his name.

"Naruto! Naruto, fuck!"

He grabbed her wrists, pinning them above her head, dominating her completely. For all her strength, in this moment, she let him take control. She needed it. She needed to feel his power.

"You're mine," he snarled, the fox within him close to the surface.

"Yours!" she agreed, her eyes rolling back. "I'm yours, Kit! Give it to me!"

The tension built until it was unbearable. Naruto felt the coil in his belly tighten. Rumi’s internal muscles were spasming around him, milking him.

"I'm close!" she screamed.

"Come for me, Rumi!"

He drove deep and held it there, grinding against her sensitive spot. Rumi shrieked, her body arching off the couch, her climax hitting her like a lightning strike. She clamped down on him so hard he thought he might break.

That was the trigger. Naruto roared, burying his face in her neck as he emptied himself inside her, pulse after pulse of hot seed filling her up.

They stayed like that for a long time, locked together, trembling, the only sound their ragged breathing and the hum of the city outside.

Lemon Scene End

Naruto collapsed to the side, pulling Rumi with him so she was resting on his chest. Her white hair was a mess, plastered to her face. Her leotard was ruined, hanging off her hips.

She traced a circle on his chest with her finger, her breathing slowly returning to normal.

"Not bad," she croaked, her voice hoarse.

Naruto laughed, a tired, happy sound. "Just 'not bad'?"

"Okay," she admitted, looking up at him with half-lidded eyes. "That was... rank S."

She shifted, wincing slightly. "You wrecked me, you idiot."

"You asked for it."

"I did." She rested her chin on his chest. "You know this changes things, right? I don't do 'flings'. I don't have time for drama."

"I know," Naruto said, his hand stroking her rabbit ears gently—something he knew she only let people she trusted do. "I'm not going anywhere. I'm your partner. In the field, and... here."

Rumi smiled. It was a genuine, soft smile that the cameras never saw.

"Good. Because if you looked at another woman, I'd have to kill you."

"Scary."

"Damn straight." She sat up, stretching her sore muscles, completely unashamed of her nakedness. "Now, go turn on the shower in the private bath. I need to wash up. And you're scrubbing my back."

Naruto grinned, sitting up and admiring the view of the strongest woman in Japan walking toward the bathroom.

"Yes, Ma'am."

"And Kit?" She paused at the door, looking back over her shoulder, her tail twitching. "Don't think one round is enough. My Quirk gives me high recovery, remember?"

Naruto’s eyes widened, and then he smiled, his canines glinting.

"Bring it on."
