Y/N is seen in her Kampfer form, getting ready to go to Sakura's place.

Y/N: Well, this definitely a first for me.

Tiger: my my, your all dressed up, going on a date?

Y/N: No, I'm going to Sakura's to hangout and maybe sleep over.

Tiger: If so, why did you choose to be a girl?

Y/N: Well, I figured if I'm participating in a girls only fight, I should get more used to this body.

Tiger: (smirk) Or maybe you just love your female self and wanted to stay like that forever, right?

Y/N: (-_-) Hahahah, very funny.

Tiger: Oh don't be like that. You did lost female virginity to Sakura and Shizuku after all.

Y/N: (blush) Yeah, but since that did happen, I wonder when I'll lose my male v-card.

Tiger: Just keep being patient and I'm sure it'll happen. But since you're a girl now, any new elements?

Y/N: Well, I seem to have Fire, Water, Earth, Wind, Lightning, Ice, Metal, Light, and Darkness.

Tiger: All elements? That's rare.

Y/N: Yeah, I know, it could go either way because of it. (She started getting her shoes on but felt something on her arm and saw Tiger on it) What are you doing?

Tiger: Take me with you.

Y/N: What? Why?

Tiger: Please, you could be gone all night and I'll be to bored, please?

Y/N: (sigh) Alright fine, you can come.

Tiger: Yay!

They were about to leave but they heard Night whimpering behind them.

Y/N: Night? You want to come too?

Night: (barks happily)

Y/N: (giggles) Okay, you can come too, but you better be on your best behavior, okay?

Night barks happily in understanding and all three leave his apartment and exit out of his apartment building but then see three familiar figures near the entrance with their messagers.

Y/N: What are you three doing here?

Rabbit: Hello.

Cat: Ho ho ho! We've come to tag along as well.

Y/N: What? Tag along?

Shizuku: I heard about the invitation from Kaede, then I passed it on to Mishima and Seno. Was that bad of me?

Y/N: Uh, I'm not sure, but why do you three want to come?

Nat: Well since we're in the harem with you, we thought we could come as well.

Akane: Why didn't you tell me Y/N?

Y/N: Well, I guess it slipped my mind and-wait a minute, you all were there when Sakura asked me to spend the night at her place, remember?

The three took pause and remembered that they were there when she asked him to spend the night with her, making Akane and Nat sweatdrop in realization.

Nat: (sweatdrop) Uh, heh heh, oops.

Akane: (sweatdrop) Uh, I guess I we were there and it kinda slipped our minds.

Y/N walked up to them while chuckling and patted their heads.

Y/N: (smile) Honestly, you two are sometimes too cute for your own good.

(Timeskip)

The four are then seen in front of Sakura's apartment building, making Y/N go wide eyed at the sight.

Y/N: What am I looking at?

Nat: This is where Sakura's apartment is?

Shizuku: Indeed, this is where she lives. Her parents are diplomats overseas, so she's taken care of.

Night barks happily, making Shizuku, Nat, and Akane freeze and look at the source, which took them by surprise.

Akane: Night?

Nat: (smile) Wow, what an adorable puppy!

Shizuku: (surprised) When did it get here?

Y/N: I brought him with us. He's been staying with me since I saved him from a group of punks who were harassing him.

Nat: How horrible, but he's so cute, can I pet him, please?

Y/N: Sure, and no need to ask, he's super friendly.

Night walks to Nat's feet and lets her pet him, which made them both happy.

Nat: Wow, what a cute pup, and he seems smart.

As everyone got inside and token the elevator, Y/N rang the door bell. Sakura then opened the door and saw Y/N.

Sakura: Y/N! glad you could make it. (sees Akane, Nat, and Shizuku) Shizuku, you and the others are here too?

Nat: Yup.

Akane: Hi there.

Sakura: Well then, more the merrier. (Sees Night by Akane's leg and smiles) Night, you're here too?

Night barks happily and jumps into her arms, licking her cheek.

Sakura: (giggles) There, there, boy. Still as cute as ever.

Y/N and the others got their drinks.

Sakura: Well then, bottoms up you guys.

Everyone: Cheers!

They clink their glasses together and drink, even the messengers were in on it.

Rabbit: This is gonna go right through me.

Y/N: Cause it is, dummy, it's leaking right out of you guys.

Messagers: Huh?

The liquid was pouring out of the stuffed animals as if they were literally taking a leak. 

Sakura: Well, if you're all interested, how about some games to pass the time?

Y/N: Sure.

Akane: Okay.

Nat: I'm down.

Shizuku: Of course and I know just the game.

Y/N: What is it?

Shizuku: (smirk) Strip Poker.

The four blush at that and have trouble processing it.

Y/N: (blush) Seriously, what's wrong with you, I don't think some of them are ready for that.

Shizuku: (smirk) Why not~? It could be fun~.

Y/N: Either way, not happening until we get farther in this harem relationship. (Suddenly gets an idea) Oh, I got one.

Akane: You do?

Y/N: Yep, and it's good, a normal card game with some prizes for one winner, if I win, you girls sleep over at my place, but if one of you four win, you get a date with me.

With that, Sakura, Nat, Akane and Shizuku had gained some determination after hearing what the prize was if one of them won. Y/N saw the four staring at each other with determined looks and he could've swore he saw fires in their eyes.

Akane, Nat, Sakura, Shizuku: I won't lose!

Y/N: (thoughts) Maybe I shouldn't have said the date part.

With that, they played their game with a prize on the line for one of them and even though a few got close, Shizuku ultimately won.

Shizuku: (smile) Looks like I get to take Y/N on a date.

Sakura, Nat, Akane: Aw, but I wanted that date.

Y/N: Don't worry girls, I'll make it up to you in the future.

Sakura: (hopeful look) You promise?

Y/N: (smirk) I swear on my feminine head, I will honor that promise, and if I don't, I shall go bald. (She said sarcastically and jokingly)

Nat: (depend) Really Y/N?

Y/N: What? It's a joke, they like it. (Sakura, Akane, and Shizuku are giggling)

Sakura: Come to think of it, there's something that I would really like to share with Y/N.

Y/N: Really, what?

Sakura: Yes, it's in my room.

Sakura went to go get it while everyone else was still in the main room.

Nat: Wonder what she wants to give you?

Y/N: No idea, but aside from that, Nat, Shizuku, how do you like Night?

Shizuku: He is quite the puppy.

Nat: And very fun to have around.

Night barks happily and jumps into Shizuku's arms licking her face.

Shizuku: (laughs) Easy, there boy, no need to go over board. (Pets him affectionately)

Sakura: Oh Y/N.

Y/N: Sakura, what—

She was cut off as she saw Sakura holding what appears to be a dildo.

Sakura: (smiles) What do you think?

Y/N: (blush) Um... Sakura? What is that?

Sakura: Well, it's a dildo.

Y/N: (blush) Okay, but why do you have it and want share it with me?

Sakura: (smiles) Because I want see what it feels like when I use it on you for when we our next season together, silly.

Y/N: (blush) Oh, I see. (thoughts) I know being a girl took some getting used to but this is a whole new level, but she does seem happy to try it out and it couldn't hurt to give it a try myself, besides, I can't say no to her and break her heart. (speaking) Thanks Sakura, can't wait to try it out.

Shizuku: (smirk) Oh, you're interested in toys for sexual stuff Y/N?

Y/N: (blush) No, but given my circumstances as a Kampfer and the fact that I have a harem, it couldn't hurt to try a few things and I don't want to make her sad. (-_-) Besides, like your one to talk, miss, strip naked and make me feel good Student body president.

Shizuku: (smirk) But you did it anyway.

Nat: (blush) Sakura, where did you even get that?

Sakura: (smiles) That's a secret.

Then there was a knock on the door, which left the five of them confused.

Y/N: Sakura, we're expecting someone else?

Sakura: No. it's supposed to be us right now.

Then they heard a voice behind it, one that Y/N knew all too well.

???: Y/N!

In that moment, Y/N knew exactly who it was and froze in shock.

Y/N: No. way.

The door somehow opened and the person came in and revealed herself.

Mikoto: Heya, Y/N!

Y/N: Mikoto?! Why are you here?! How did you even know where I was?!

Mikoto: (smiles) Well, I dropped by your house looking for you but you weren't there, so I tracked you down by finding your phone.

Y/N: The fact that you said that with a smile has me worried! And did you hack my phone?!

Mikoto: No, I simply put a find my phone app on it when you weren't looking and I used mine to sync it to yours so I can find you anywhere.

Y/N: I see...

Nat: Okay, I'm starting to have the same concerns here just from that sentence.

Akane: Me too.

Mikoto: Hey, are you hungry? I made some curry.

Y/N: What is it with you and curry?

Mikoto set a huge pot of curry on the table.

Akane: (confused) How did that even fit in her bag without spilling?

Nat: I have no idea.

Afterwards, it was now nightfall as they were all eating the curry Mikoto brought.

Tiger: Which would you prefer to eat, entrail curry or curry flavored entrails?

Dog: Hmm... I think I'd prefer, you know, plain flavored entrails.

Sakura: Hey Y/N, you're sleeping over tonight, aren't you?

Y/N: Yeah, I promised you I would.

Nat and Akane: Huh?!

Y/N: What's with you two? You were there when she asked.

Nat: Yeah, but why do you get to sleep over in her place?!

Akane: She's right! Who knows what kind of vile stuff Sakura would do to you the second I'm gone! (bends her opens with her hand)

Y/N: Calm down, girls! Remember, I love you all equally. And Akane, you know she's not like that.

Mikoto: I have plenty of more curry to go around.

Shizuku stood up from the couch as she had a scoop of curry before she walks behind Y/N and pours it onto her, causing her to scream.

Shizuku: It must've just slipped.

Y/N: (mad) Hey, what are you doing?!

Mikoto: (grabs Y/N by the shirt) What the hell?! You're not supposed to wear curry! How dare you waste it! (starts spinning her around)

Akane: M-Mikoto, calm down, it's not her fault.

Shizuku: Kaede, do you think you can lend Y/N your shower please?

Sakura: Uh, yeah, sure.

Shizuku: Also, do you have more of your toys in your room?

Sakura: Yeah, feel free to look if you want.

Shizuku: (smirk) Thank you.

(short timeskip)

Y/N and Sakura are seen in her bathroom as Y/N takes off her clothes.

Y/N: Seriously, I don't know what goes on in that head of hers.

Sakura: Same here, I thought I knew everything about her, but to find out these secrets.

Y/N: (smiles assuredly) Don't worry, I'm sure she's still the same person you remember.

Sakura: (smiles) Me too.

Y/N: By the way, why are you here with me?

Sakura: Well, I wanted to run down everything so that you don't switch something up and (blush) to uh, maybe ask you...

Y/N: (-_-) You want to join me in the shower?

Sakura: (blush) Yes.

Y/N shakes her head in disbelief and amusement.

Y/N: Alright, you can join me, besides I may need your help to clean my hair properly since it's so long.

Sakura: (smiles) Of course.

Sakura takes off her clothes as Y/N finishes stripping and they both take a shower together while she helps clean Y/N's long hair from the curry.

Sakura: Your hair is long and beautiful. Although, I couldn't help but notice your body's been developing as a girl.

Y/N: Huh, what do you mean?

Sakura: You mean you didn't notice? I mean, you're getting bigger in... (blush) Well...

Y/N: (smiles assuredly) You can tell me, I maybe a guy but I'm a girl right now and we are together.

Sakura: (blush) Your body... Your body has grown a bit. Look at you.

Y/N looks at her body and saw that Sakura was right, her female body has grown a bit, especially a few of her assets.

Y/N: (blush) Huh, guess you're right.

Sakura: Is this a Kampfer thing for you?

Y/N: Not that I know of.

Sakura: Maybe we should ask Shizuku once we're done.

Y/N: Good idea.

Once they were done in the shower, they went to Shizuku and asked her about Y/N's sudden changed. They found her exiting Sakura's room.

Shizuku: Y/N's female body is different? 

Sakura: Yeah, we've noticed that it's grown a little, especially in certain parts and areas.

Y/N: Has it happened before?

Shizuku: Not that I could think of. This must be new. I want to try something.

Y/N: Go ahead, I guess.

Shizuku then did a sudden grop on one of Y/N's breasts.

Y/N: (blush) W-what are you doing?

Just then, Y/N's began to glow. But instead of blue, it was glowing pink.

Sakura: Y/N, you're bracelet!

Y/N: What the...?!

Then Y/N was glowing pink as her body began changing.

Sakura: What's happening to you?

Shizuku: Interesting.

Y/N: (blush) I-I don't know... But I feel hot...

Then Nat, Akane, and Mikoto appeared from the corner.

Nat: What's going here? (Sees Y/N) W-what's happening to her?

Akane: (worried) Y/N?

Suddenly, Y/N's hair was now growing and getting longer and longer to the point it was almost completely touching the floor. Then her height started to increase although it was faster and was showing to be a lot more taller than the rest of the girls now being 6'2 instead of her normal height her clothing was completely almost gone because of the height. 

Y/N then felt her chest be in pain in which it then it started to grow a lot more to the point they were now bigger than her normal breasts size by one inch no in fact by one millimeter and the top barely holding on with a nipples revealing because of it although it was fully hard. Then her thighs were getting thicker and somehow even smoother than any girl so far and finally her butt started to grow more and showed how big and plump it was as her pants can barely be kept together and were already to be teared apart anytime.

The girls were shocked but Shizuku had a smirk in her face, like she was intrigued by what was happening.

Mikoto: Holy...! She's huge!

Sakura: (Shocked) Shizuku, what happened to her?

Nat: I'd like an explanation too!

Shizuku: It appears her bracelet is capable of changing her appearance.

Akane: We know that, it's the same with every Kampfer, but what's with this?!

Shizuku: It's a strange one. I have no idea what it is, but I believe it was caused by the wearer's thoughts.

Nat: Thoughts?

Shizuku: Indeed, it might be a one time thing, but it can't hurt find out. What's going on in your head Y/N?

Y/N looks at her body which was bigger and muscular with large breasts and a big butt.

Y/N: I don't know. I feel stronger, but I hope it is a one time thing, I could never show my face at school with my Kampfer form like this.

Akane: (blush) You're so big and buff...

Y/N: Shizuku, any idea how long this'll last and how I can quickly go back to my normal Kampfer form?

Shizuku: Not long. I'd say roughly two minutes or three.

Y/N: Good, then this won't happen again, right?

Shizuku: Not unless you wanted to.

Y/N: I never want to, ever.

Akane: Good, cause I honestly can't get close to you with your muscles so big, it's a little intimidating.

Nat: No kidding.

Sakura couldn't help but stare at Y/N's muscular female body with a blush on her face.

Y/N noticed her looking at her temporary massive muscle body.

Y/N: Sakura, why are you looking at me like that?

Sakura: Your body... You're very hot with that.

Sakura towards Y/N as she place her hand on her thic and muscular thigh.

Y/N: (blush) W-what?

Sakura: So thicc and muscular... It's turning on me. I couldn't help it.

Y/N: (blush) Huh?

But then her bracelet started glowing pink again before her body started glowing the same color and she reverts to her normal Kampfer form.

Y/N: (sighs in relief) Oh, thank god, the three minutes are up and I'm back to normal. Well, normal Kampfer anyway.

Sakura: (blush) I-I'm sorry for that. I didn't know what I was thinking.

Y/N: It's ok, it wasn't your fault. But this stay between the six of us and we never speak of it or mention it to anyone, that clear?

Girls: Got it!

Shizuku: But you must be wary, Y/N. If there's a chance, your body might change again into the same thing or something different.

Y/N: (nods) Got it, but hopefully it doesn't happen again. Now, with that, I'm tired and ready to hit the sheets. Anyone else?

Girls: Yeah.

Mikoto: Uh, actually before we do, I want to get something through.

Y/N: What is it?

Mikoto: (blush) Well, since you have a harem going on and I was wondering if you would, maybe...?

Y/N was confused by what she was saying but it immediately clicked in her head.

Y/N: (surprised) You have feelings for me too?

Mikoto: (blush) Yes.

Y/N: So you want to join my harem?

Mikoto: Can I?

Y/N was thinking it over for a moment and looked at the others who gave nodding smiles of approval and so, she looked at Mikoto with a smile.

Y/N: (smiles affectionately) I'd loved to be with you Mikoto.

Mikoto: (smiles) Thank you Y/N! (kisses her on the lips)

Y/N kisses back for a few seconds before breaking off from it.

Y/N: Welcome to my harem, hope you'll get used it and get along with Shizuku and Sakura and whoever joins in the future.

Mikoto: (smiles) I'm sure I will.

Y/N: Great to hear, now, time for bed. Now, a question from me and I'm pretty sure I already know the answer: Do you five want to sleep in the same bed with me?

Girls: Yes!

Y/N: Okay, then let's go. I'm ready to sleep like a log.

They all went to Sakura's room and got ready for bed as they all get comfy on the bed with Y/N in the middle.

Y/N: Night girls, sweet dreams.

Girls: Night Y/N.
