Chwange Me Chapter 1: Boom Boom (Patreon)

“Everyone sit down,” Aizawa-sensei said walking into the classroom. A few seconds later a girl with blue hair as long as Deku’s and a happy expression walked into the room.

“Let me introduce you all to Rikka Sakurai. He will be joining us starting today~, “Aizawa said plainly to them, causing everyone to look down and see that “he,” was wearing a skirt!

“Haaaaaahhhhhhh!?” The entire class exclaimed all at once not believing him. How could such a cute and happy-looking girl be a guy!?”

“What the fuck is this shit!” Bakugo yelled, but his sudden outburst didn’t give him the attention that he usually got.

“Are you really a boy?” “Are you sure that you’re not a girl that identifies as a man?” If you’re a guy, then Minetta is the most popular guy in school!”

All of the students in Class 1-A were in an uproar by this. There was just no way that he could be a guy!

“Shut up and listen or you’re all expelled!” Aizawa yelled at everyone to shut up and sit down. “Let Mr. Sakurai give his introductions and then ask him questions since the first period is a free study,” he said rolling up into his sleeping bag.

“Hi, I’m Rika Sakurai, I am 15 years old and yes, I am biologically a male, but I sexually identify as a woman. My mother has a quirk called: Soul Resonance. It’s a simple quick that allows one to see another person’s soul. She saw that when I was born I had the body of a boy with the soul of a girl, so she named me Rikka after my grandmother.”

“When she first told me about this when I got old enough couldn’t believe her, though as time went on I began to accept myself for who I really am. I like cute things and wearing girl clothes, but I don’t have the desire to change the body I have lived with my entire life. In my opinion, having one extra appendage or not should not determine our gender. You can refer to me as he/him or she/her, I will not be offended by either.”

“As for my quirk, that’s where things get a bit complicated ~. My quirk allows me to make others sick. It’s nothing permanent or harmful, but it is quite useful. For example, if professor Aizawa attacked me I could give him pink eye, making his power worthless.”

“Interesting~,” Deka said, jotting Rikka’s quirk down in his notebook.

“Alright everyone, now you can ask your questions, but try to be quiet about it. I’m going to sleep,” Aizawa said before passing out.

“OMG~! You’re so cute~!” Uraraka said back to him, getting up from her desk. “Is your uniform custom-made?”

“It is,” Rikka said back to her, its custom made, by my mother~.”

“Wow~! That’s amazing~!” Uraraka said back to him. That must explain the larger skirt than was provided by the school.

“So since you’re a guy that dresses like a girl and identifies as a girl, does that mean that you are allowed in the girl's locker room?” Mineta asked him, thinking up yet another perverted scheme.

"No, I will not," Rikka said to his disappointment. U.A. had already seen to it that people similar to me have their own changing room.”

“Well, it’s not like it’s totally out of the picture Mina said, trying to be as friendly as she always was.

“No, it’s alright~,” Rikka said back to her. “I don’t plan to cause anyone any problems,” I’m just glad that you’re more accepting of this than my last school. No one accepted me and I was bullied a lot. It’s nice to see that you’re more accepting than most people.”

“You don’t need to worry about that here,” Momo said to Rikka. “No one will ever judge you for who you are. U.A. is accepting of all kinds of people. I mean look we have Mineta,”

Upon hearing that comment everyone in the class including Mineta laughed. He knew what kind of guy he was and wasn’t ashamed of it.

“Who the fuck cares what you call yourself!” Bakugō yelled out angry that everyone was swarming the new kid like he was some sort of celebrity. “Don’t you dipshits remember that we’re here to become heroes not to talk about our gender identity!”

Bakugō might be an attention seeing jerk, but he was right. There was no use in making a big deal about this. Rikka just wanted to let everyone know about it, not make a deal about it. He really was a big sweety-pie deep down inside.

“Yes, I do believe that Bakugo-kun is right~,” Rikka said back to them. “Um before we continue this conversation could someone walk me to the gender-fluid bathroom?”

“I shall do it my lady~,” Aoyama said, trying to act like a dashing prince as he always did.

“Non, no, no,” I’ll take him,” Uraraka said to everyone. “You boys need to learn to properly behave before you’re allowed to be left alone with him. There is no telling what’s going on in your heads right now. Come Rikka, this way,” Uraraka said, grabbing his hand before leading him out of the room.

“I’m sorry about that, but the guys in our class don’t have a good track record with not being creepy,” Uraraka said, thinking of Mineta, Aoyama, Bakugo, and the rest. It was best that Rikka who identified him or rather herself as a girl to stay closer to the girls for the time being.

“Thank you for worrying,” Rikka said back to her, but as I have said before, your kindness is more than enough to make me happy to be a member of your class.”

“I just wish that Bakugo was a bit nicer to you,” Uraraka said to him. “He’s not a bad guy, but unfortunately his personality isn’t the best.”

“It’s fine, I could tell that he cared about me to a certain extent when he yelled out before,” Rikka said. “He’s just a tad bit misunderstood~.”

“Wow, first day here and you already have Bakugo down to a peg,” Uraraka said complementing him. “…Oh here we are,” Uraraka said to Rikka as they reached the gender-fluid bathroom which was a tad bit further out compared to the other bathrooms. “I’ll leave you to do your business and I’ll see you back in class~!” Uraraka said, skipping away.

“I’ll see you in a bit~!” Rikka yelled out before entering the bathroom.

“Sigh, I’m glad that they didn’t notice Rikka said pulling up his skirt to reveal a diaper. It was still dry and safety concealed, but he was worried that they might find out that he had to wear diapers as a side effect of his actual quirk.

BUZZ! BUZZ! BUZZ!

Rikka's phone started to ring, and Rikka picked up seconds later.

“So how’s it going~,” the girl on the other end of the phone asked.

“Himiko it’s still the first period,” Rikka said revealing that he was in contact with Himiko Toga of The League of Villains. “You could have waited until lunch at least to contact me.”

“Ugh, I can’t listen to you with that voice,” Himiko said back to him. “Change back to my bestie before you continue~.”

“But Himiko-”

“Lalalala~! Not listening~!” Himiko said, refusing to talk to Rikka in his current state.

“Ugh, fine,” Rikka said, giving in to his bestie’s demand. Within a matter of seconds, Rikka began to shrink down, his hair became longer, and his body became more feminine. As a pair of breasts form on his chest his manhood was taken away turning her into a complete female.

“Is this better~?” Rikka asked her bestie.

“OMG! Yes, it is~!” Himiko happily said over the phone. Finally, after a full two months without contact, she was able to talk to her bestie again.

For those that are confused, the answers to all of these questions are quite simple. Her name was Rikka Sakurai, a member of The League of Villains. And her true quirk was to make anyone she touches into a diaper-dependent person just like her. And as an added bonus to her quirk, she was as to say able to make certain alterations to her victim's minds and bodies~. The only downside of her quirk was that she was fully diaper-dependent as well.

The sob story that she told her classmates was true besides her quirk, but what she didn’t reveal to them was that her father killed her mother for giving birth to as he called her, “a freak,”. This was when she was five years old and her quirk activated, allowing her to transform into her true self for the first time.

Those pathetic heroes were worthless. They couldn’t save her father and none of them helped her as her family forced her out on the streets when she was ten. She spent 5 years doing what she had to in order to survive, but of course, in their eyes, she was in the wrong! The world of heroes was filled with nothing but giant babies playing dress-up and she was going to reveal that to the world.

Well, that was her plan until Himiko found her. Himiko helped Rikka out when she was at her lowest point. She protected and love Rikka when no one else would. And when Himiko joined The League of Villains there was nothing stopping her from joining them as well. In fact, she was welcomed with open arms by All For One and he had big plans for her. He even gave her the Villain alias Chwange Me.

The first task that she was given was a simple one. Infiltrate U.A. and use her powers to transform the students in U.A. into Villains. While they would be afflicted by her quirk diaper effect, it was still more than enough to cripple the future heroes of the world.

“So, have you decided on who will be the first victim~?” Himiko eagerly asked. She loved Rikka’s quirk and couldn’t wait to see it in action again~.

“Bakugō Katsuki,” Rikka said back to her. “That little angry baby escaped us before so it’s only fitting that he becomes ours this time~. I do hope you’re ready because I’m going to deliver that baby to you real soon~.”

“I can’t wait~!” Himiko said. “Soon they will have a new baby daughter to raise. It was going to be great~!

After that Rikka ended her call with Toga and transformed back into her male form before adding back to class. There he continued to answer their questions and partake in classes with them. In order to make sure that no one would find out about his true quirk he made it so that he would be the only one diapered and the other person be afflicted by the “sickness” this was something that took him years to master and one false move could cost him.

Over the next several days Rikka continued his daily routine, but he soon noticed that he was being watched by none other than Bakugō himself. It was as if that big baby was asking to be turned~!

At the end of the day on Friday, Rikka walked out to a secluded part of the woods near the school with Bakugō following after him. When Rikka finally made it to a clearing, Bakugo finally showed himself.

"Stop right there!" He yelled jumping out of the bushes, trying to catch Rikka red-handed only to discover a girl wearing a giant soaked diaper!

“Eeeeeekkk~!!! What are you doing here!?” Rikka yelled, using this perfect opportunity that Bakugō gave her. The moment that she entered the forest she became a girl, and since her back was turned to him, there was no way for Bakugō to notice.

“…Who… who the hell are you!” Bakugō asked, slowly walking over to the girl. “Where’s Rikka did he do this to you? I knew that guy was up to something, but to think that he was doing this sort of thing to girls that’s… huh, you kind of look familiar, what’s your name?” he asked getting close enough for her to grab him.

“Can’t you tell?” Rikka asked the foolish boy, grabbing Bakugo’s leg, and activating her quirk. “It’s me Rikka, but I guess that I dumb little baby like yourself wouldn’t be able to understand that, now would they? I guess that you can just call me mommy~!”

“Huh what the fuck are you-”

CRINKLE!

“What the fuck!?” Bakugō yelled out, seeing a giant diaper-shaped bugle from his pants!

“It’s alright little baby~,” Rikka said sweetly to him. “Mommy is just going to put you down for a little nap~. Sleep tight~,” she said as Bakugō felt a wave of sleep wash off him.

“N-no… I… I won’t give… in…” Bakugō tried fighting the pressure of sleep but was helpless against it. There was nothing he could do as he fell right into Rikka’s open arms.

“… Himiko, package secured~,” Rikka said on her end of the phone. “We’re going to need a pickup~.

Rikka had accomplished taking in her first victim, but this was only the start of the fun~!

CRINKLE!

“Huh? Where am I?” Bakugō asked himself, before seeing that he, or rather she was tied to a chair!

CRINKLE!

“What the hell!? Why the fuck am I a girl!? And what’s with these breasts!?”

CRINKLE!

“Where the fuck is that noise coming from!”

“Tsk, tsk, what a naughty baby we have here~,” Rikka said, walking out of the shadows with Toga by her side.

“I think she’s adorable~!” Himiko said, happy to see that their first baby was so cute~.

“So, what do you think we should call her?” Rikka asked Himiko, not paying attention to the struggling Bakugō.”

“Well her name was Bakugō Katsuki, so how about Kitty~!?” Himiko asked her bestie, looking at the grumpy baby.

“OMG~! That’s perfect~!” Rikka said back to Himiko.

“What the fuck are you two fucking bimbos’ talking about!?” Bakugō, soon to be Kitty, yelled at them! Get me the fuck out of here! I already told you losers that I would never be a villain!”

“Hmm, is that so~? Then how about we fix that because as your mommies we can’t let you go down the wrong path no can we~?” Himiko asked, eager to see Rikka work her magic~.

“Mom? What the fuck are you-”

“Good babies listen to their mommies don’t they~?” Rikka said, activating her quirk. It was time to make several alterations.

“Mommi- no! You bitches aren’t my mommies! …Wait what the fuck! Why am I saying, mommies!? What the fuck are you doing to me!?”

“Good babies don’t use bad words~. Good babies accept the names given to them by their mommies~. Good babies obey their mommies and take down those foolish heroes~,” Rikka said, slowly changing Kitty’s mind.

“G-good… baby… hero… hero bad… no… no this isn’t right!” Kit-Bakugō said to her-himself. “You… you can’t mess with my… mind, you meanies~!”

“Good, good, it’s working~,” Rikka said. Kitty was a hard one to break, but what was about to happen would easily break her~.

“Good girls are always happy when their mommies are happy and mad when their mommies are mad. Good girls don’t need the potty as the potty is always with them. Diapers are good and potty is bad~. Good girls should get rid of all their big kid thoughts and live as our precious diapered baby forever~. Go on show your mommies that you are a good girl~.

“Ngggghhhh~! N-no! Kitty no want… Kitty fight!” Kitty tried to fight the urge to use her diapie and get rid of her big girl thoughts, but her mommy’s spell was too strong. She wanted to be a good girl and be pampered by her mommies.

Her mommies only wanted what was best for her. They wanted to love and take care of her. Ugh! There was this weird pressure that was preventing her from doing so. She needed to get rid of it and then her mommies would praise her. Come on just one more push~!

Frrrrrrrrrrpppppppppppp!!!!!

Kitty messed her diaper, getting rid of all of her big kid thoughts as well as memories of ever being Bakugō Katsuki.

“That’s a good girl~,” Himiko said to their new daughter.

“Now all that is left is to slightly modify her quirks and show her to the world~!” Rikka happily said as Himiko started to prepare Kitty’s new adorable villain uniform made for her by her uncle Twice~.

-1 Day Later-

“This just in, a new female Villain is out wreaking havoc. She goes by the name Boom Boom, and it is perceived to be highly dangerous! Her quirk seems to allow her to make tiny explosions inside of her…her… her diaper and this results in it becoming more powerful in terms of attack and defense as well. Several heroes have already felled to her already. If there is anyone out there with information about her whereabouts please let us know,” the news reporter said standing in front of the area Kitty made her supervillain debut yesterday.

“I think that I knew where she is,” Rikka said to Himiko, who was sitting next to her on the couch.

“I do believe that I know as well~,” Himiko said back to her.

“Mommy Himiko, Kitty made boom boom again~,” Kitty meekly said, slowly getting out of her crib wearing her favorite pink tutu and shirt. Her diaper was completely full and now she needed a diaper change. What a truly good baby she was to ask for a diapie change, and to even remember that it was Himiko’s turn, she was such a good girl~.

Now all that was left on Rikka’s mind was who to choose next. There were so many students to choose from. So, which one was she going to have fun with next~?
