It was suppose to be a normal patrol. Walking around, making sure people are safe, but of course something had to happen. Here Deku was looking at his reflection, only instead of a teenage boy, a teenage girl was reflecting back.

"It's not that bad Midoriya. It could have always been worse, at least you can still go to school." Togata, ever the optimistic, says to cheer up the greenette. "Yeah. Only I'll be the opposite gender." Deku sighs, his voice sounding higher and feminine. He and Togata were walking around until they saw a man steal a purse from a woman. They were able to catch him but before the police took him away, he sprayed some purple gas from his hands and the police released him, fearing it was poisoned.

Deku inhaled some but it wasn't poisonous at all. However, the criminal got away and they returned the purse to the woman. At least that was what Deku was told before he passed out and found himself in the nurse's room. He felt different and when he looked in a mirror he felt like fainting.

He was shorter and his hair and eyelashes were longer. He looked to find his body had a more feminine appearance. He had a more curvy figure, his hips widened and his rear was definitely more rounded, (and his little Deku was no longer present). But he was having the most difficulty with his chest. He always tried to not look at any girl's cleavage because he always blushed and made a fool out of himself. But now he had breasts that could definitely beat any of the girls in Class 1-A or any other girl in school, except Cocora who always had a gorgeous figure, (but she didn't brag or draw any attention to it).

He was so busy muttering of all the countless possibilities that could go wrong, he didn't hear the door opening, "Deku/Midoriya?" He froze. He shakily looks behind him to find Asui and Uraraka at the door, the two girls with a look of disbelief. Togata steps in to break the silence, "Hey Uraraka And Asui! What are you two doing here? You don't look hurt?" He asks them, curious as to why they are here.

Uraraka shakes her head and regains her sense of awareness, "Oh! Uh, actually, we have a similar situation." She nervously says. Asui walks behind her and grabs a person, revealing a tall handsome man around the same age as them. Togata and Deku look at the boy. He was tall, about 2 inches shorter than Togata. He had short, semi-wild, shiny, brown hair with his bangs parting to the right-side of the face. A muscular body, which is highlighted by a very familiar costume, and he had beautiful blue eyes.

A realization dawned upon Deku, "Jayori?!?" He exclaims. Togata takes a double take and looks at the hero costume the brown-haired male is wearing. "Yep. Hey Mirio, Izuku. I guess you could say it has been a crazy day hasn't it?" She says, her voice was deeper but still sounded soft.

Recovery Girl checks on both of them. After a while she tells them the results, "Well the good news is it's not permanent." Deku and Jayori sigh in relief, "But it appears to last depending on how much of the substance the user put into it, causing the effects to last on how much 'power' was put into it rather than how much someone inhaled it." She adds.

The two changed students look at each other in worry. "But it will wear off eventually?" Uraraka asks. The old lady nods, "Of course. And judging by how much you two have in your systems. I'd say you will return to your normal selves in, oh my 3 months. That man must have either been frightened or had a lot of practice." She answers.

"WHAT?!" Deku screams. He starts to shake, "How am I suppose to deal with being a girl for 3 months?! I already feel so dirty just standing here." He thinks to himself. He was brought out of his mental scolding when he felt a pair of strong hands on his shoulders. "Hey, Hey! Izuku it's going to be okay. We're pro-heroes in the making and it's going to take more than some weird, but interesting, quirk to slow us down." Deku looks to find Jayori smiling at him.

Despite having a more masculine face, she still retained that soft look that always made Deku feel calm. "I know you must feel so dirty right now, I have a little guy between my legs," this caused Deku to laugh a bit. "But my point is, we'll get through this together. I promise." Jayori finishes. "Yeah! We got you guys." Togata butts in, wrapping his arm around Jayori. "And we can help too, Ribbit." Asui adds. "And don't worry, we'll handle anything that comes at us!" Uraraka cheers.

Deku smiles and nods along with them. "Guys, I don't want to make this awkward, but I feel like my costume is suffocating me." Jayori adds, pulling at her costume's collar. "Oh right. Good thing I always bring an extra pair of clothes and underpants." Togata grabs his bag and gives Jayori his spar set of clothes, "Thank you Mirio. And I'm guessing you had these because of how you use to phase through stuff." She stops and realizes what she said.

She was about to apologize when she felt a hand on her now broader shoulder, "It's okay. And yeah I did. I still carry some around just in case." He says smiling, despite taking a shot that costed him being rendered quirkless for the time being, he still looked on the brighter side and helps in any way he can.

Jayori smiles sadly, she knew the guy didn't regret his decision because it gave Eri a chance to use her quirk for good. She walks over to a nearby bed and pulls the curtain over to have privacy. Deku smiles, but realizes that he too need a change of clothes as well. He blushes and looks over to the two females, "Uh, O-Ochako, A-Asui, I uh, need some more a-appropriate clothes too." He says, his face cherry red.

The two look at each other and back at Deku, "If you two think that now he's a girl you can dress him in whatever you want." Everyone looks over to find Jayori with a stern face. She wore a blue shirt with white sleeves that stopped at her elbows and jeans with a brown belt to keep them up. She had a large red jacket that she left unzipped. She walks over to the girls and looks at them, "We are going to shop for some clothes that will make sure everything is 'comfortable' and that's it." She says with a smile, but everyone knows that she does not want Deku to feel forced to wear girly clothes.

Uraraka and Asui agrees, but Uraraka felt scared to tick her off while Asui understood completely, (Midoriya is a gentle soul and she did not want to make him feel uncomfortable). After Recovery Girl informed the teachers, the five teens received the rest of the day off and went shopping. After buying some new clothes and receiving some new uniforms from Togata, (he asked the school, but he didn't reveal anything to other students who asked him why he had them).

Soon everyone went back to the dorms, Togata bid them goodnight and the four had to sneak their way around the others, they manage successfully. The girls said their good nights and went to their rooms. Jayori walked Deku to his room, "See you tomorrow." He told her.

Before he entered his room he felt his arm being grabbed and finds himself with a pair of lips on his. He blushes realizing that Jayori is kissing him. She pulls away and looks into his green eyes, "Sorry, I just haven't kissed you in a while. And to be honest, your lips are a little more plump. Other than that, you're still the same, Izuku." She says.

She then walks to her room. Deku enters his room and falls face first onto his bed. He hugs his pillow, although it was a little difficult considering his huge breasts now. "This is going to be some of the hardest 3 months of my life." He tells himself. Sleep soon took hold and he fell asleep.

The next day, Class 1-A was going about their normal stuff. "Hey. Where's Midoriya and Cocora?" Kirishima asks. Everyone realizes that they haven't seen nor heard from them since yesterday. Before anyone said anything, the door opens to reveal exactly who they were talking about but didn't expect a surprise.

The two walk into the class, avoiding eye contact at first. Sensing the tension, Uraraka stands up and walks over to them, "Soooooo, there was a bit of a thing that happened and now Deku is a girl and Jayori is a boy." She states. Everyone just stares at the two, "Wow. Midoriya got a nice ra-" Before Mineta could finish, Asui slaps him with her tongue.

Deku takes a deep breath, "Yeah and we will be stuck like this for three months, so it's not permanent." She says, still looking down. Mina walks up to Jayori, "Wow. You are a lot taller now Jayori, how's the view up there?" She asks. Jayori smiles, "Pretty good Mina." She humors the pink girl. Everyone then got over their shock and started asking them about their predicament.

"OI!!" Everyone look to find Bakugou stomping towards Deku. Said person started to shake nervously, "You think I'm suppose to believe this crap!" He yells. Kaminari steps in front of him, "Whoa dude! Calm Down." He tries to get Bakugou to calm down, but the explosive boy pushed him out of the way. "I bet this is some kind of prank you made up with your 'girlfriend' just to get a raise out of me! But did you have to be so extra!?" Bakugou yells and grabs Deku's chest.

"HIYAH!" Deku squeals. Everyone froze, including Bakugou. He gripped the greenette's breast harder and Deku moans. The blonde feels a hand on his shoulder and turns his head to find Jayori with her eye twitching. "Katsuki. Please release Izuku." She calmly asks him with a strained smile.

But before he could, he felt a slap on his face, "Kacchan! You Baka!" This surprised the other students, Deku just slapped Bakugou. He had a red handprint on his face and looked up at Deku. Before anything could happen, Aizawa woke up and looks at the scene before him. "Alright I don't have time for this. Everyone take your seats and I do not want anymore conflict understand." He states. The teens took their seats but when Deku went to his, out had a huge crack in it.

"Uh, Aizawa Sensei. My desk is broken." He informs him. The black-haired man sighs, "Look sit in Cocora's lap. Just don't cause another scene." This surprised Deku along with his classmates. "But Sensei! This is inappropriate behavior! As the top hero school in Japan we must set a good example!" Iida said standing up from his desk, using his hands to chop the air. "I am tired and if you want to lecture me, you might as well talk to a wall." Aizawa states with a scary face. Iida sat down and Deku walked over to Jayori.

"Um, do you mind?" He asks. He had a blush on his face. "I don't mind if you don't." She states, a blush on her face too. For the rest of the day, the two stayed close together.

They were currently in Deku's room. "Um, s-so h-how are we going to d-do this?" Deku asks. Jayori rubs her neck, "Well, I can tell you about how to deal with being a girl and you can help me with being a boy." She says. She felt a pair of arms around her now narrow waist and looks down at Deku. She tried not to pay any attention to the pair of breasts pressing against her and hugs back.

"Are you okay?" She asks. Deku nods, hiding his face in Jayori's flat yet muscular chest, "I'm fine. I just want to cuddle with you. You were right, I miss you too." He looks up and smiles at Jayori. The blue-eyed male tackles her onto the bed. Deku let out a yelp, "Sorry. I just, you are too cute for your own good." She says.

Deku laughs and combs his smaller hands into Jayori's hair. It was still soft but was shorter than what Deku was use to. Jayori refused to move but Deku didn't mind. These next few months were definitely going to be interesting.
