KonoSuba - Identical Potion (Patreon)

Killing slimes, murdering frogs, whatever small task had to be done Kazuma had already done it. He had done so many pathetic quests that the same quests constantly had become boring. Though if he tried harder ones usually his teammates would get him almost killed or actually killed in some way. Maybe he was just blessed to go through the same things all the time. At the very least; he was not going hungry. Though even if you have a home and food, having to do mundane work was still a hassle. How does someone change up such a set way of life?

SLAM

“Yo, Wiz!” Kazuma storms right through the magical item shop door and slams his hands down at the front counter making the well-endowed Wiz jolt up in place nervously. “So…” With a soft grin Kazuma brushes his dark brown hair out of his dark green eyes and he stares at Wiz with a smug yet somehow begging glare. “I was just thinking how amazing you are Wiz. Like wow, I can’t believe how amazing you are. A beautiful maiden and really the only good woman in this whole town.”

Unsure how to respond properly Wiz simply smiles and nods resting her hands against the countertop. “Well… um, I do appreciate the comment Kazuma.” Wiz was speaking in her usual softer way, at least if Kazuma was being nice. She just would get nervous or shy and speak softly. At the very least she usually was never rude while talking, unlike some girls Kazuma knew. “Did you need anything today? I don’t currently have any requests for you sadly.”

Kazuma had dealt with such dismissive tactics before. People always trying to avoid the points he was getting to. Though overcoming such things was what he was best at. If his charming looks were not working well enough, he had another approach to get what he desired. Slamming his hands back against the counter to add emphasis and to startle Wiz again Kazuma blurts out his words. “Please Wiz I really just need something that will finally let me do some harder quests. Please help me! I need something. Anything! I’ve been doing the same thing over and over and over. I’m going insane here Wiz. Really you’re a kind person so it could be cruel to ask but I know no one else would help a jerk like me. So please you really gotta just help me out here and help me become stronger! But your items are way too overpriced and shady but maybe even you have something that could help someone so pathetic like me!” Just to add to his display Kazuma even cocks his head back holding his arm against his forehead like they do in the movies. “Really this is a charity, and you’d be a bad person if you didn’t help me in some way, I’m sure you understand.”

Wiz takes a careful step back and fidgets her hands together. Kazuma could tell she was a little put off by how he was now panting from blurting out everything at once but she was not running away. Though she did have that slight nervous stutter in her voice. “K-Kazuma…” Wiz crotches down behind her counter and starts rummaging through a few trinkets, some glass clangs together now and again among other noises. “You’ve helped me plenty… so I mean the least I could do is offer something to you. I never knew you were this desperate though.” Relief fills Kazuma's eyes, as well as some concern since nothing ever goes this well for him. “Now.” Wiz finally stands back up and sets a small chest down on the counter. “I have a certain magical item that is usually used to help people new to the city… though. After a lot of things happened it was banned.”

The chest was right there, beckoning for Kazuma to open it up. Though really, of all the items Wiz had she brought out some weird chest? “Wiz…” Sighing deeply Kazuma drags his hand across his face passively pointing at the box. “You’re telling me the first idea you get is to give me some banned item…? What if it kills me or something? It had to be banned for a good reason, right?”

Both hands placed on the chest Wiz unlatches the chest and turns it around opening the lid. The inside of the chest was padded red like in the movies. The only thing inside of it is a crystal vial filled with a green liquid. With her kindness, Wiz smiles brightly and opens her arms toward Kazuma offering up the contents. “The only problem I heard people had with it was that it would copy the powers of another adventurer. It does make you far stronger than you currently are though. Just the skills will be set for you. This had a good and bad effect since lower-ranked adventurers would end up becoming high leveled and have no idea how to properly use their new skills.”

In theory, such a potion sounded like it was everything Kazuma wanted. He already had to deal with people that had bad skills that do not synergize. As long as he was at a higher level, he could just use his current skills or find useful ways the new ones could help him. “Well…” Kazuma grabs the potion from the chest and looks over it. The crystal vial felt pretty nice, he could probably sell the bottle to some sucker if he kept it and filled it with some junk. “I guess I can give it a try.” Uncorking the crystal vial Kazuma stares into the bottle. He was a little nervous about the whole thing, but Wiz smiling beside him reassured him a little at least. “Well, this doesn’t seem like the best idea. But I’ve done worse.” Pressing the bottle to his lips Kazuma cocks his head back and chugs down the contents even the small drops. Removing his lips from the bottle then he sets the vial back down into the box and wipes his lips of anything left. “There. I drank it down. This thing work right away?”

Hand on her cheek Wiz closes her eyes for a few moments. “Hmmm…” Nodding her head slowly to herself she opens her eyes back up and happily responds. “It should work within a minute or two. The potion needs to circulate throughout the body so it knows how to level you properly and whatnot.”

With such a response Kazuma was a bit more nervous over what he just drank. Though even with those concerns his body did feel like it was suddenly becoming stronger slowly but surely. Taking out his adventurer card to just check his level it was slowly going up as well. Just for some reason, his name on the card was now erased as the levels kept increasing. “Well, it looks like I’m getting stronger at least. It seems like it’s actually working.”

Wiz nods and rests her hands back against her countertop. Kazuma and her both knew not many would shop at her store so the effort was a little pointless. “Well, Kazuma did you need help with anything else? I will have to charge you for any other item though.”

Kazuma puts his adventurer card back into his pants and rubs at the side of his neck looking over the shop. “I mean… I could like clean it for you… it’s pretty spotless.” Dragging his finger along the windowsill it did not even have any dust. “Yeah Wiz… beside the potion thing I’m pretty sure I’m good for today. Didn’t even bring money with me, so no jobs then ya know.” With a stretch of his arms, Kazuma yawns slowly, his light brown hair brushing against his shoulders. “Okay well I guess I should…” Kazuma carefully touches at his silky clean light brown hair. “I guess I should.” Gliding his hand along the hair it did not just go to his shoulders, it seemed like it went a little past his butt. “Wiz…”

A content smile on her face Wiz tilts her head looking toward Kazuma. “Yes, what is it? You seemed like you were getting ready to leave now.”

Both of Kazuma’s hands squeeze at the bundle of hair he now had, his eyes flashing a bit annoyed staring at Wiz. “What the heck is all this?!”

Hands touching gently against her own light brown hair for a moment Wiz a little worriedly now scratches at her cheek. “Well… I mean, it looks a lot like how my hair looks. It seems rather nice on you, are you trying a new hairstyle?”

The troves of hair wave at Kazuma’s side, he could barely believe it was his actual hair. Tugging on it more would not make it come off, it was not some cheap prank it seemed. Even trying to deny it, this hair was his. “I just don’t understand this… the potion changed my hair completely? Why is it so long?” Triggering a clear flag before him Kazuma is given his answer right away. His skin gets a tad colder, a bit paler as well. It made him shiver a little at first but slowly his body seemed to adjust to the temperature. Kazuma was familiar with the feeling, it was like Wiz really. She was an undead, after all, so her body was usually pretty cold not having the constant blood flow and all. Kazuma nods his head sagely to himself in that thought, the dots were pretty obvious to connect but part of him did not want to. “I mean… it can’t be that. The potion… giving powers someone else has… it wouldn’t have been banned cause of that.” Chuckling nervously under his breath Kazuma could notice Wiz was squirming in place uncomfortable. She was not sure of everything going on but Kazuma figured he should be the one reacting like that! The changes happening were obvious to him though, sadly. “Maybe the thought has crossed my mind once or twice…” A low sigh passes Kazuma’s lips. His skin was just completely different now. Smooth yet cold, his face was starting to feel a little pained in the jaw as well like it was shifting slightly. He least had dealt with worse things, but the more apparent change was things like his butt. Just patting at his backside, he could tell pretty easily that he now had a much fatter ass. Slapping at it made the thing shake. “I mean… at least I would be able to look at myself in the mirror.” Kazuma gives a glance at the reflection in the shop window and admires the shapely figure he was now sporting. He looked like some female version of himself cosplaying as some male hero. “Yeah, I mean not bad.” Nodding calmly and even more sagely, truly Kazuma had been through worse situations. “Wiz!” With a slam of his hands back on the shop counter Kazuma angrily stares Wiz dead in the eye. “Your potion is turning me into a girl! But even more than that… I’m becoming like you or something!”

The poor passive Wiz twiddles her thumbs around averting her eyes from Kazuma’s. “W-well… I suppose you are starting to look a lot like me in some regard.”

THUD

As if on cue Kazuma’s chest bursts out ripping at his white tunic. Large plump breasts thud right onto the countertop trying to burst from Kazuma’s tunic more than they already had. Kazuma half expected such a result, but it gave a perfect chance for him to wave his hand over the large melons to emphasize his words. “I think it’s pretty clear with these giant things that I’m becoming like you! You can’t deny it now Wiz!”

Very sheepishly Wiz reaches her hand out and pokes Kazuma’s left breast watching as the boy’s eyes wince in response. “W-well they do seem very real, don’t they?” Resting her hand back on her plump chest Wiz quickly glances between her breasts and the ones now coming out of Kazuma. “Well… Ah, I can surely find some sort of cure for all this! Or um, a way to reserve things… unless, um well you could just be fine with all of it too, right? You are stronger now…”

Both hands squeezing at his new breasts mindlessly Kazuma shakes his head in disagreement. “You think I want these things all the time?” Kazuma does not let go of his new breasts, just keeps fondling them more, his face blushing. “They’re neat and everything but I prefer them on the other person. Not myself. Even if this makes me as strong as you Wiz, I don’t want to just become some clone of you.”

Wiz walks around the counter and brushes some of her hair behind her ear looking over Kazuma a bit more seriously. “Well… Kazuma. Mmm, I really am sorry. I wanted to help you. But I should have looked into why the item was banned beyond the minor details… So I will do what I can to find a cure for this alright?!”

The white tunic on Kazuma was now showing a bit of his stomach from the large breasts hiking it up. Turning to face Wiz the breasts also swish, jiggle and bounce with just a twisting movement. “Ah…” Kazuma crosses his arms under the large breasts and tries to keep himself calm. Not like he was in some terrible pain. Though it did feel like his manhood had crawled back up inside him leaving him a man without a weapon. Though rather than freak out over that he keeps focused on matters at hand. “Fine. I’ll stay here I guess… just go find something to put me back to normal. Does this count as a curse or something? I don’t even know how this sort of magic or alchemy crap works.” About to speak up Wiz covers her mouth for a moment watching as Kazuma’s dark green eyes change to Wiz’s hazel brown color. Fortunate or not Kazuma could tell his body was still morphing. He seemed to be a girl fully now, he was not that stupid to not realize that. Though something in his throat was being pulled around. Just running his smooth fingers against his neck his adams apple was no longer there. A shapely body, female characteristics, the light brown long hair, the eyes, even the face shape had changed. Kazuma was just Wiz’s twin now from head to toe. The only difference was Kazuma now looked like Wiz cosplaying. “Yeah… Wiz the way you’re looking. I know. I can feel the changes. I think most of them are done now. Look, just…” Kazuma walks around Wiz and pushes her out the shop door. Wiz though was already in a daze again from hearing Kazuma’s softer voice, she had not thought to be talking to herself in such a way today that was clear. “Just go out and look for some cure thing. I’ll um, make sure no one messes with your shop alright?”

Wiz tentatively nods staring back at Kazuma with concern. “I-I… um. Kazuma. I’m just worried still. You look exactly like me now. Like you’re my twin sister. You even seemed to have become a lich as well. The potion could make you an exact copy of me… if you’re pressured in some way or attacked magically. I’m unsure of what the side effects could be.”

Kazuma rolls his eyes and swishes his hand back and forth toward Wiz’s direction to get her moving along. “Don’t worry so much over it. I’ll just hide in your shop. Look around for something, tell me whatcha find. We’ll figure this out! Now get going and help me!” Kazuma smiles and shuts the shop door watching Wiz give another final nod and hurriedly run away. “Jeez…” With an exasperated sigh, Kazuma walks behind Wiz’s counter and sinks into the chair behind. “I really look like some clone of Wiz… hah, a lot of comics and junk have the guy turn into a chick and do the usual. Though I become Wiz? I guess bodyswap stuff happens… this is a little different I guess.” The last thing Kazuma wanted to do was whine even more about his life. Even if he was a girl, he did not need to refer to himself as one! Even if he looked like Wiz he did not need to be her! He was a man, with manly desires! “Hmm…” Kazuma grabs onto both of his now softer thighs. Through his gray pants, the thighs were pleasant and soft like a new pillow you just laid your head on for the first time. “Having the thighs I’ve rested my head on… I guess I could have gotten stuck with the useless goddess’s body. Eh well, I suppose she has a nice ass at least.” Kazuma quickly stands back up and grabs at his butt again. “Though this one does feel better for sure.” Something was calling to Kazuma, like some unseen force, he had to do something else. Going into the back of the shop Kazuma wanders till he reaches Wiz’s room. Maybe it was just curiosity. He had the body for now anyway so may as well do the cliché and see what it is like to be a girl. Throwing his clothes off completely Kazuma grabs some dark purple panties from Wiz’s things and slides them up his shapely legs till they squeeze snugly against his waist. He then takes out a dark purple bra and looks at the strange device. Pressing it against his new breasts did nothing. “Surely such a relic can be used somehow…” Looking over it Kazuma discovers a clasp in the back, clipping the bra on properly now his breasts still clearly swayed but a bit more controlled. Then Kazuma opens up Wiz’s closet and sees several purple dresses all the same design, with wiz’s robed jacket also with several different copies. “Ah… she actually has the same outfit for every day huh… I always wondered how some of these people did it…” Not thinking of the strange detail longer Kazuma pulls the dress over his head first watching the long light purple dress cling a bit to the shape of his new body. He didn’t often see Wiz without the robe jacket along with the dress so it was a tad different. “I feel like I’m staring at her changing or something doing this…” Smiling softly into Wiz’s mirror Kazuma nods contently to the image before him. “Nice.” Completing the look Kazuma pulls on the robed jacket clipping the cross-batwing broach in place at the neck. Of course, he also slips on the dark purple shoes with it. Now in the mirror he really did look like Wiz’s clone, complete copy from clothing, voice, face, hair, everything. “This really is weird… girls clothing feels so different too. Why does the material feel so much better?”

DING

The bell to the show door rings, so Kazuma quickly runs back to the front desk. If Wiz had returned, he had to hear her findings right away. “Wiz are you— Whhhyy are you here?!”

Aqua flourishes her hair over her shoulder. Her face screamed annoyed, Kazuma had seen it plenty of times, of course getting that sort of reaction would probably make a few people annoyed. “Huuuh?” Her annoyed voice too, Kazuma got annoyed just hearing it. The useless goddess puts a hand on her hip and walks over letting her dumb blue skirt keep flashing too much of her thighs and butt as usual. “What did you just say?! I came here today because I thought I would grace you with my presence. I had some money saved up and was thinking of getting a special item.”

Kazuma cannot help himself. He groans and rolls his eyes crossing his arms under his chest. “Hah, like someone like you could actually afford anything here. No installment payment plans here, we don’t accept old liquor bottles either.”

Upset seemed to be the correct word to use for Aqua’s face. The useless goddess leaps right over the counter at Kazuma and grabs at the new girl’s collar as they both fall to the ground. “What the heck did you say brat?!” Aqua sits her butt right on Kazuma’s thighs her hand gripping at his collar. “You’re talking like Kazuma all a sudden?! Did he tell you to say that crap! I’m not gonna put up with it you know!”

It was then Kazuma had realized he was still wearing Wiz’s clothing. “W-wait! Wait you spoiled goddess! I am Kazuma!”

Aqua very effortlessly sits back up and pushes Kazuma so his butt was lifted in the air facing her. “I don’t wanna hear it! What sort of lame excuse do you think that is! I said I just wanted an item and you’re being a jerk!” Aqua pulls back her hand and smacks it right across Kazuma’s ass making it quiver in place. Kazuma groans against the floor, in theory, such a thing should not even bother him. He was stronger now, but it was like his body was forcing him to be bullied. “I’ll make you a pile of dust you dead dummy!” Aqua’s hand now begins to glow, her hand smacking once again across Kazuma’s ass but this time it makes him drool a little. The slap felt like it had traveled across his whole body somehow.

DING

“Kazuma?” Wiz walks back into the shop and sees no one behind the counter. “Kazuma?” Walking back behind her counter Wiz now sees Aqua still slapping Kazuma’s plump ass again and again. Kazuma’s body seeming to fade a little. “Aqua! Wait stop that!”

Aqua lifts her glowing hand back up slowly and turns her head to the real Wiz. “Huh…” Turning her head back she looks down at Kazuma. “Wiz… and… Wiz?” Looking between both Aqua slowly gets off Kazuma and looks back at both the girls again. “Two Wiz… more than one…”

The ex-male stands dusting off her backside. For some reason each time she got hit it made her feel, strange. “A-Aqua… y-you shouldn’t do…” Blinking a few times herself, Kazuma was starting to find it hard to not speak in a certain way. “Aqua, I told you, I’m Kazuma, that’s the real Wiz… s-something happened.. .a-and well. S-sorry about yelling earlier.” Kazuma wanted to rip out her hair saying the words herself. Though it was starting to feel hard to even refer to herself as a man. She wanted to call herself a girl, at least she still knew her name was Kazuma. “U-um, your turn undead thing, though please don’t… I-I really am sorry about everything. I think that was m-messing with me.” Kazuma’s head was hurting that much was for sure. Something about Aqua’s assault on her ass was making her act a lot like how Wiz usually would with Aqua.

“Pfffft” Trying to hold back a laugh tears were starting to well in Aqua’s eyes. “O-Oh. H-hahaha.” Aqua was starting to spit up, she just could not hold back, she starts laughing loudly right there between the two Wiz’s. “Bahahahahahaha! Are you some sort of idiot!” Slapping her leg Aqua wipes some tears from her eyes and grabs right at Kazuma’s breasts. “You’re really Kazuma?! Hahaha, oh wow!” Squeezing her hands tightly against Kazuma’s breasts she lets out a soft squeak trying to move back. “Hey, hey, for how you treat girls maybe you being one works fine huh? Hahaha, oh wow this is great. What me hitting you with my spell was making you act more like the real Wiz?” Aqua starts to grin and both her hands start to coat in a holy glow, her hands squeezing at Kazuma’s breasts even harder. “Come on Kazuma~ Call me your beautiful Goddess Mistress Aqua and I’ll let you go~ Forget the item, this is a wonderful present.”

Wiz slides along the floor between the two and waves both her arms at them trying to get Aqua’s attention at least. “W-wait wait, please wait Aqua! She’s, she’s like me now, even a lich, you could kill her like that, a-and her mind could become even more like mine if you keep doing that too much!”

Kazuma’s head was spinning, drool starting to run off her lips as a soft moan escapes her. Both the girls in front of her blush but Aqua still was not letting go. “M-mm…” Kazuma was unsure what to do. The last thing he wanted to do was appease the stupid goddess, but his body only wanted to do that. “I-I’m sorry… p-please Beautiful Goddess Mistress Aqua, l-let me go.”

Roll of the eyes, a snort of the nose, Aqua pushes Kazuma into Wiz and walks back around the counter. “Hah, well she did what I asked. Have fun with him Wiz. But go ahead and just keep him like that. The jerk would probably be more useful to everyone if he was more like you anyway. Or at least he’d listen to me more.” In a huff, Aqua pushes open the shop door and walks on out leaving both the Wiz’s to themselves once again.

Things were at least quiet again without the useless goddess around. Though Kazuma could tell Wiz was a bit confused with everything, and something else too. “Kazuma?” Wiz helps Kazuma get back to her feet properly instead of staying leaned against her. “Why… um, why are you in my clothes? Did, did you go in my room? Aqua didn’t dress you up like me, did she?”

Kazuma could very clearly feel her cheeks get warm, were Liches even suppose to be able to blush? “Um, well, yeah… I sorta, decided to throw my clothes off and switch into these.”

With even more concern Wiz puts a hand to her cheek and stares at Kazuma. “Um… Kazuma, maybe, um. Would you like to go to the bath with me? I have something I need to talk to you about.”

The question was odd but Kazuma had no real reason to refuse. “I mean, sure, I can go to the bathhouse. Though I didn’t bring any money with me… and well the clothes. I didn’t mean to go through your things.”

Wiz grabs at Kazuma’s wrists and pulls the girl right out of the shop, both walking together through the street. It seemed to Kazuma that Wiz did not need to prattle on further about more. The seriously concerned look in her eyes was making him worry more though. They walk and walk till getting to the bathhouse. Wiz pays for Kazuma and she takes her through the woman’s changing area. Being an odd time of day, no one was even there so it was not that awkward. The awkward part was Wiz helping Kazuma remove her clothes, both of them naked with just rolled-up towels as they walked into the bathing area. “Now let’s sit.” Wiz gets into the steamy water first sinking into it and resting her back against the edge of the steamy tub. Going with the pace Kazuma sits down right beside Wiz and sinks herself into the water. Even as a lich, the warm water felt nice against the girl's cool skin, Kazuma could only figure Wiz had nice skin most likely because of baths and probably some other care products. “Now… Kazuma…” Wiz calmly breathes out looking right at Kazuma. “I wasn’t able to find anything. In the files I found about the potion I saw no way to reserve the effects. That was the main reason it was banned. I don’t know if we can ever turn you back… you may be stuck like this… forever.”

It was hard to just go and respond to such a statement. Kazuma had no idea what to even say, her mind could process things normally, but her body was acting like Wiz more. She only had limited control over her own body now. “U-um th-that’s fine. Really.” Kazuma wanted to say it was not fine at all, he had his quick fun it was time to change back! “I’m still Kazuma, I know I’m me… so even if I have to stay like this. W-well I’m glad it was you Wiz.”

Wiz’s face starts to blush, her eyes looking over her own naked body in front of her in the water. Then Kazuma starts to do the same, a blush coats across her face. “Really Kazuma… you are a good person, even if you can be a bit silly sometimes.”

Hand on her breast Kazuma smiles at Wiz. “We’ll get through things. We’re sisters after all aren’t we? It may be hard, but I’m sure we’ll figure things out.” Kazuma bites at her lip a little but nods her head as if to confirm her own words. Her mind wanted to be more like Wiz, her body was Wiz, if she was going to be stuck like this Kazuma had to try to keep some part of the man known as Kazuma. “Just make sure Aqua doesn’t go around attacking me again… I-I don’t want to just die. I want to still be Kazuma.”

Wiz nods back and slips her fingers through Kazuma's sinking back into the water to now get her hair wet. “I don’t want to lose you either Kazuma. I’ll do what I can to make sure you stay here with me. Maybe I’ll be able to find something too. S-so you can properly change back, this was all sort of my fault anyway.” Looking into the water Wiz squeezes at Kazuma’s hand. “At the very least, I’ll try and find some ways to protect your mind. And don’t worry… you can stay with me for now. We both have the same body now anyway.” Wiz’s eyes dart back along Kazum’s body, her cheeks still kept red in blush. “Though it may take some getting use to, suddenly having a sister around. I’ll make sure you have food, and maybe I can even show you how to use some of my skills.”

Sinking into the water herself Kazuma finally squeezes back at Wiz’s hand. For all the jokes, for all the complaining and whining she could go on about. At the very least, the person she got stuck with was the only actual good person around. Things would change from now on. “I know you’ll do what you can for me, I’ll try and keep myself useful too.”
