Deku realized what happened

That night, All Might had called Deku to the beach. After his mother had gone to sleep, he sneaked out and went to meet his mentor, despite his illness. At least it was getting better, and now he'd finally be able to ask All Might about it.

“All… Might…” He was out of breath, both from the illness and from having run all the way to the beach.

“Are you sick or something? You shouldn't be that tired just from running here.”

“Ever since I ate that hair, I've been feeling weird- None of my clothes fit, and I've had a horrible fever. I've been in my room the whole time to make sure I didn't get anyone else sick, but I think that girl from the exam must've caught something. Is this because of One for All?”

“Any sorta sickness should've been flushed out by Recovery Girl. And I don't remember anything like that when I inherited. Wait… do you have a mirror in your room at home?”

“A mirror? Why?”

Pulling out his phone and snapping a photo, All Might turned it around to show Deku.

Staring back was a full-body picture of Deku- or what had to be Deku.

The outfit, the location, the startled pose- all the same. But Deku’s body had changed.

His face was softer, his body slimmer. His hips and chest had expanded, however- and looking closely, he could even see a bulge in his pants.

“Wha- what happened?”

“No clue. Anyway, the reason I actually called you here. Congratulations on passing.” As All Might moved to place a hand on Deku’s shoulder, he flinched away.

“D-don’t touch me,” Deku said. “The girl from the exam, in that video- I saw she looked a little sick, too. Whatever’s happening to me might've happened to them too!”

“Hm. Well, I can assure you that whatever's going on isn't a sickness- Recovery Girl would've taken care of it. It's probably some sort of reaction to One for All- although not one I've seen before.”

“Am I going to die? Against the gimmick, I couldn't handle the power-”

“You're not dying, you're just not in a complete state! Someone who grew a tail wouldn't have full control over it after just half a day.”

What about someone who grew breasts?

“The better you learn to regulate that power, the better you'll become at using only as much **** as necessary. I'll try and look into what's going on with your body on the down-low. There's still a month before school begins. Get out of the house. Get back to training.”

“If you say so.”

Uraraka was feeling weird.

Ever since the practical exam, her body had been on fire- she'd dealt with it through the written exam, and when she went to talk to Present Mic, but once she got home it was too much to bear.

What is going on with me? She wondered, grinding her hips into her mattress. And why does this feel so good?

The next day, the symptoms had stopped- but the changes certainly hadn't gone away.

Deku had woken up early to take a good look at himself in the bathroom- or herself, as it turned

[out.

It

](http://out.It) was as it had seemed at the beach- she had almost completely become a woman.

Almost, because her male genitals were still there- bigger, even. Deku didn't have a ruler, but her dick seemed to be about ten inches long, with balls to match.

That aside, she was decidedly feminine, from her face, to her B-cup breasts, to her hips, to her legs. She even felt a vagina beneath her balls.

Managing to resist the urge to start masturbating (her libido hadn't gone away, even though the other symptoms had), she got back into her room before her mother woke up.

She hadn't told her about All Might, or the hair, so she wasn't sure how she was going to explain this, but she had to try.

When Inko woke up, she knocked on Izuku’s door again. “Sweetie? Has your fever cleared up yet?”

“Yeah, mom, but… something else happened.”

“Will I get sick if I come in, or you come out?”

“I… don’t think so?”

“What happened, Izuku?”

“I- I’m not sure.”

As the door opened, Inko saw (almost) the true extent of her child’s illness.

Jumping back in shock, she reached out a hand. “I-Izuku? Is that you?”

“It’s me, mom. I don’t know what happened, but it started after the exams. The fever’s broken, so I don’t think I’m contagious anymore.”

“After the exams? Did U.A. do this to you? We-we can still-”

“No, I want to got there. I don’t think anyone did this on purpose- Maybe someone’s Quirk misfired. But U.A. probably has facilities to deal with stuff like this. But I can’t let it stop me from being a hero.”

“Oh, Izuku…” Throwing her arms around her son/daughter, she held them tight. “I’m just glad you’re feeling better. I’ll start making breakfast.”

-

“So, what do we do about your clothes?” Inko asked over breakfast. “I can call U.A. to get you a female uniform, but the rest of your wardrobe might be a problem. I mean, those pajamas barely fit you.”

“I- I can check what fits me long enough for me to go get a few new outfits,” Izuku said. “But do I really need a female uniform?”

“Well, it's your choice, of course, it's just-”

“Fair point. I'm still not sure how I want to go forward with this stuff. Like, do I have to get my gender changed? I'm not even sure if this is permanent.”

“I’m not sure, either,” Inko said. “Just- you know I love you, no matter what, right?”

“Yeah, I know.”

Izuku was still contagious, it seemed.

After they left to go get new clothes, Inko felt her own fever begin to make itself known.

Trying to ignore it, she decided to clean Izuku’s room. She hadn't been allowed in for a week- it was surely a mess.

Stepping inside, the first thing she noticed was the smell. It was as overpowering as it was curious. What is that smell?

Following the smell to where it was strongest, under Izuku’s desk, she saw the source- a small puddle of a thick, sweet-smelling substance.
