“Hmm, doesn’t Momo seem a bit different lately,” Deku said, watching Momo act cute and girly. It had already been several days since the talent show, and everyone could tell that something was different about her. Deku wasn’t sure, but since that day, he could have sworn that he was hearing a strange crinkling sound near both Rikka and Momo whenever they moved. It was probably just his imagination, so he decided to push that thought aside.

“I like it,” Koji said, watching Momo finally being true to herself. “She seems happy~.” Truth be told, Koji had known what happened to Momo, Mineta, and even Bakugo. His quirk allowed him to communicate with animals, allowing him to figure out what was happening since day one.

Though he decided not to tell anyone since he found himself attracted by what Rikka was doing. She had the power to turn people into there cutest forms, their best forms. Just look at Momo, and Koji already saw what she did to Bakugo and Mineta. She couldn’t help but want that for himself. Koji has never been masculine as it were. He loved animals and cute things. He liked them so much that he was often bullied for it when he was younger. After seeing how happy Momo was, he knew that this was what he wanted.

“I guess that you’re right,” Deku said to him, heading over to Illda and Uraka when lunch started.

Once he was alone, Koji looked around and saw that Rikka and Momo had already left. Using his quirk Koji was able to figure out that they went up to the roof, and Rikka was once again in her female form. Wasting no effort Koji made his way up to the roof where Momo and Rikka were having their fun.

CRINKLE! CRINKLE!

“What a good girl you are, nice and dry~,” Rikka said, finishing up checking Momo’s diaper. At first, she was worried that keeping Momo enrolled in U.A. would be too much for her new baby, but it would seem that she was wrong. Momo was an excellent big sister to her younger siblings. Her intelligence reminded the same after her change, though she did possess all the baby tendencies that she needed to become Rikka’s baby.

“Thank you, mommy~!!! Momo is doing her best, so no one finds out who Momo’s mommies are~,” Momo happily said to her mommy. Ever since her change, she felt like all the fear and self-doubt had vanished. She loved the attention she was receiving, thanks to her mommy’s help.

“Oh my, it looks like we have a guest, ”Rikka said, noticing that Koji was watching them, though she didn’t seem to be that surprised. She had researched everyone’s quirks when she came to U.A., so there was no way that she didn’t know that He knew. Out of everyone, the two students that she really needed to look out for were Koji and the invisible girl. She couldn’t be quite sure about invisible girl, but Koji was a different story. He was gentle, kind, and sweet. He was the perfect person to become one of her children. All she had to do was wait, and it would seem that the time has finally come.

“Rikka I…I have a request~,” Koji said, looking down at the ground, unable to look her in the eyes due to pure embarrassment.

“Aww, sweetie, that is no need to ask mommy for a request~,” Rikka said, making her way over to the poor boy, lifting his chin up so he could see her.

“M-mommy?” Koji asked, confused by her words. She knew why he was here, yet she didn’t try to harm him. Could he really trust her?

“That’s right sweetie~,” Rikka said, taking his hands, and guiding him over to Momo. “You came here because you want to be a cute baby princess just like Momo, don’t you~.”

“C-cute… baby… princess…” Koji mumbled what she said to him, hoping that this was real.

“That’s right~,” Rikka said, happy to see that she had her first ever volunteer.  “You’ve come here because this is what you truly want~. Just look at Momo. She’s so much happier than she was before. And you wouldn’t believe how happy Kitty and Minnie are~. Don’t you want to be happy? Don’t you want to be cute~?”

“I… I do, but…” Koji couldn’t deny that the reason he came here was to ask Rikka to transform him into a cute girl. He was willing to wear the diaper if needed, but he knew that it was impossible. He may like cute things, but he was nothing more than a hideous rock creature. There’s no way that he could be could.

“Sweetie, is there something wrong~?” Rikka asked, piecing together that Koji-chan had an inferiority complex about his appearance. “There is nothing to be ashamed about wanting to be cute.”

“C-can I really?” Koj asked her, feeling that he could put his faith in her.

“Of course you can~. Here take a look at Kitty, Minnie, and Tia,” Rikka said, showing pictures of her precious babies playing with one another. “You could be as cute, no even cuter than they are, but in order for me to help you, you need to help me~.”

“W-what do you want?” Koji asked nervously. He couldn’t believe that he was actually considering this!

“That’s good~. I like my babies to be obedient~,” Rikka said, teasing her soon-to-be baby~. “And you don’t have to worry, it’s nothing illegal~. You see, changing Momo into my obedient baby was easy, since there wasn’t much to change~. As for Kitty and Minnie, they took a bit more effort, and because of their changes, they are no longer able to attend U.A. without gathering suspicion. I just need you to convince the class that this was all your idea, and then I can transform you into your most inner cute self, the version that everything will love and pamper~. Can you do that once simple task for me~?”

“Y-yes.” Koji couldn’t believe what he was agreeing to, but this was something that he had wanted for a long time now. There was no way that he could give up on this chance.

“Good~. Now come along lunch is over, and you have an announcement to make to you dear classmates~,” Rikka said, as she and Momo led Koji down back to the classroom, while telling him what he had to say to the class.

“Um, ev-everyone, I have an announcement to make~,” Koji nervously said while being forced to the front of the class by Rikka (male form) and Momo.

The entire class stopped what they were doing and looked at Koji, who was having a hard time staying still with all these eyes on him. He never thought the day would come when he could express his true feelings to his friends. Rikka, or rather, his soon-to-be mommy, was finally going to grant his wish.

“For t-the longest time, I have had a s-secret. I have h-hidden it until now b-because I was scared, but I no l-longer wish to be scared. I want to be a woman. A-all my life I have been different for other boys m-m-my age. I know it’s because I’m a g-girl trapped in a male body. I r-recently met someone that can help me. They possess a sex change quirk, and are willing t-to help me.”

“What!?” Deku yelled, shocked by what he was hearing. How could Koji agree to something so soon? “Koji, you can’t rush into this! What did your family say about this?”

“I am not r-r-rushing into this,” Koji said back to Deku. “I have been thinking about t-this for years, and my family fully supports me~. I hope that you will support me as well~”

“Of course we will~!!!” the entire class said, gathering around Koji to comfort him as he explained that for the next few days, he would be out while undergoing the transformation and that when he or, rather, she gets back, she’ll look completely different then she does right now.

“Alright, everything is done~,” Rikka(female) said, waiting for Koji with Momo at the front gates of U.A. “The school has been informed of your absence, and now it’s time to bring you to your new home~. Follow us~”

“Y-yes,” Koji said meekly, following after them as they lead him to their hideout, where the other children and Himiko were waiting for them~.

“Mommy~!!!!” The three cute girls jumped up to their feet and ran over to Rikka and Momo the moment that they saw them enter the room.

“Mommy, bwig sis-ter, wee missed you so much~!!!” Kitty yelled, speaking for her sisters.

“And we missed you~,” Rikka and Momo said to them, giving each one of them a big hug.

“Oh my~. Is this one the newest baby~?” Himiko asked Rikka, slowly observing Koji. “They have potential~. Hello sweetie~, I’m pretty sure that you know who I am, so let’s skip introductions and start this show~..”

“W-what do I have to do~?” Koji nervously asked Himiko.

“Oh, I like this one~,” Himiko said, watching Rikka place her hand on Koji’s shoulder. “Just sit back and relax sweetie~.

“R-relax? …Huh, why do I feel lightheaded?” Koji asked, feeling strange.

CRINKLE!

“Is… is this a diaper?

“Such as smart girl~. Of course it is~” Himiko said to Koji. “Nothing but the best for our little cute stone baby princess~!”

CRINKLE!

“I’m a b-baby princess?” Koji asked, his face turning red from being called cute. “T-there’s no way t-that I’m cute~.”

“Oh, really~? Because it looks to us that you are~,” Rikka said to her, showing out a mirror to show that Koji had completely transformed without her even realizing it. While her face and body were still made out of stone she couldn’t help but feel attracted to her own beauty. There was no way that this could be real. It had to be a trick. Not to mention her… her breasts now blocked the view of her new thick poufy diaper.

“H-how?” Koji asked, unable to hold back her tears of joy. This was everything that she had ever wanted. It had to be a dream.

“Because, sweetie, this was your fate~,” Himiko said to her. “You were always supposed to be an adult baby just like your sisters, but you never realized it. Admit it already, you’re cute~.”

“I’m… I’m cute~” Koji said, unable to look away from her reflection, drawn in by her own beauty and cuteness. She was now nothing more than a cute baby girl that needed attention. This was her fate? Was this true? Did she make the right decision As she began to compliment her choices, she couldn’t help but start to feel this strange urge growing inside of her that wanted to be a baby again. Things were simpler when she was a baby. She didn’t have any responsibilities and was always pampered. She even did have to—

Hsssssssssssssssss~!!!

“Eeeppp~!!!!!” Koji screamed, falling to her knees, realizing that she was wetting herself uncontrollably!

“Aww look at the little baby~,” Himiko said, mocking her, as their newest daughter wet herself. Her reaction was so cute, but there was nothing for her to worry about this was natural for her.

“It’s alright sweetie. Your sisters were the same when they were turned~,” Rikka said to her. “Soon, you won’t be able to notice it at all~.”

I-I will?” Koji asked, tears running down her eyes.

“Of course you will. All babies are like this~,” Rikka said back to her. “And you do know that only good girls get diaper changes from their mommies~. Do you want a diaper change~?”

“Y-yes… yes m-mom…mommy~,” Koji said, unable to say no to Rikka, beginning to accept the fate that she had chosen.

“Very good~. Your mommies love that you understand when you need a change. Now let’s help you out of that soaking thing~,” Rikka said, as they changed their new baby out of her wet diaper. She was so much more obedient than the others. Now all Rikka needed to do was make a few adjustments to her baby's mind to make her the perfect pampered villain.

“There nice and clean~,” Rikka said, finishing Koji’s diaper change while editing her mind to obey her without question. She was so much easier to deal with than the other girls. Hmm, the name Koji doesn’t fit her new baby. What should she pick?

“What about Kenkou-chan?” Himiko said to Rikka, thinking of a name herself.

“Not bad, I like it~,” Rikka said, agreeing with her, while at the same time modifying Kenkou-chan’s quirk. From now on, Kenkou-chan could only control baby animals. If she tried to control adult animals then she would be forced to mess herself. As for her villain name, hmmm, what should it-

Frrrrrrrrrrrrrppppppppppppppttttttt!!!!!

“M-mommy I dorry~!!!!” Kenkou-chan screamed, tears rolling down her eyes. Before she could even realize it Kenkou-chan had messed up her freshly changed diaper. She was happy that her mommies gave her such a cute name that she wanted to have her animal friends sing them a song, but it didn’t work!

“There, there~,” Rikka said, cradling Kenkou-chan in her arms. After her change, she became quite small, so holding her was not a problem for Rikka. “You made such a hard mess now, didn’t you~. It’s alright your mommies are here to make you feel better~. Now get you changed into your pajamas, you messy little cub, and ready for bed. We have a lot of fun tomorrow~.”

-1week later-

“Hi everyone, it’s me, Koji, now Kenkou-chan~!” she said, standing in front of the class after being gone for a week to get used to her new body.

“Woah! You look amazing!!!” All the girls and several of the guys in the class yelled at the same time. None of them could have even imagined that Kogi could be transformed into such a cute girl. It was truly a miracle. And even her shy personality was gone.

“Settle down,” Aizawa said to the class, shutting everyone up. “Yes, as you all can tell, Kenkou-chan is now a girl. This is a very important time in her life. All of you shall support her and take care of her when needed. If I find that anyone tries to shun or harm her, it will be a week’s detention for the first warning. Do I make myself clear?”

“Yes Mr. Aizawa!!!” the entire class said back to him.

“Good. In addition to this, I must inform you all that another diaper villain named Messy Cub. She seems to control an array of baby animals, making it impossible for many people to attack her. She wears a baby fox fursuit, so there is no way to identify what she actually looks like, so please stay vigilant. We are doing everything in our power to make sure that these new villains are captured and brought to justice. Kenkou-chan, you may sit down now.”

“Yes Mr. Aizawa,” Kenkou-chan said, walking to her seat while everyone was unaware of her messy saggy diaper underneath her skirt. Her mommy would need to change her again~.
