Teenager Erasermic Can Kick-Ass/Fluff

(This a request from my Ao3 account) 

De-aging Erasermic Au:

It was a nice day in Japan for school, it was warm and sunny with no cloud in the sky. This weather was perfect for heroic class with the still number one hero(All Might will always be number one in my heart), All Might. Do you know what this perfect weather is good for as well? Another villain attack! This was another time that the League of Villains didn't attack U.A. This time it was by a villain with a de-aging quirk, which no one knew about yet. The villain was called Teenage Dream, seems like someone was trying to take Todoroki's title of being Katy Perry, not cool man! The villain was male and they looked like the entire music video of California Gurls by Katy Perry threw upon him. He had the lavender bob style hair, the Californian tanned skin, and the outfit of California Gurls but it had little clouds on it, but instead of heels, they were thigh-high boots.  The villain looked around the same age as of most year one students. 

So, our everyone's favorite gay teacher couple with the help of Midnight went to defend everyone while the rest of the staff went to bring the class to safety. While fighting the villain, Hizashi couldn't help but sing Teenage Dream and this made Shouta want to laugh and hit him upside the head at the same time. "Can't believe someone is trying to steal Todoroki's brand!" Hizashi jokes as he dodges the villain's punches, Shouta rolled his eyes. "Focus, we don't want to get hit by his quirk. We don't know how he can use it." He told his husband as he tried to use his scarf to capture Teenage Dream. 

After the always tired teacher captured the knock off Todoroki, Hizashi goes to him and Shouta. Once he was there, the villain blew some type of glittery white powder in their faces, which made the married couple yelp in shock and tried to get it off. Then, the villain tries to escape but Midnight knocks them out with her sleeping powder quirk. Not long after the R-Rated hero captured the Teenage Dream, the English teacher, and the homeroom teacher passed out from the dust. Midnight brings them to Recovery Girl after the police showed up and took the evil-doer in custody. Something shocking happens to the married couple after being in the nurse's office for five minutes, they have been turned into teenagers! The quirk doesn't look like it won't last more than the rest of the day.

Midnight laughs at this. She can already see their students' reactions to the gay power couple as teenagers or how cute they were when they started their relationship. She had All Might get them a change of clothes from the boy's locker room in their size so they can change after waking up. They wake up after half an hour. They were confused and didn't remember anything from being adults, all they remembered was going on a date to a cat cafe and Shouta sleeping over Hizashi's that night. Nemuri had to explain to the cute, teen couple of what happened to them. That explains why they were wearing clothes that were way too big for them. The two boys look at one another and blushed as they changed in front of each other. At this age, they just started dating. 

After changing, Midnight brings the class 1-A. Hizashi and Shouta were holding each other's hand as they went to the classroom. When they got to the class, the students were shocked. They didn't expect them to be so small and awkward, well even more awkward for their English teacher because he was the most outgoing and social person they knew. Hizashi was hiding behind Shouta, being shy, and Shouta looked like he was trying to protect him from evil, it was adorable. The girls and Kirishima of the class were trying to hold back their fangirling squeals. "It's okay, Sunshine. I got you, I won't let them hurt or make fun of you." Shouta told him with a light blush on his face as he turned to his loud boyfriend, Mina almost let out a fangirling squeal. "I know, Moonbeam." Shouta's sun whispered back. The first student to crack with the squealing or what I should say squawk was Tokoyama, surprisingly. 

The students look at their class birb. "What, they are too cute!" The class emo told them with a blush on his face, his classmates smiled at him as they agree with him. "Do you think they can still fight as pros?" Jirou asked out loud, their homeroom teacher glared at her. "Of course we can fight as pros, right Zashi?" He asked his shy boyfriend if there is anything that Hizashi hates other then bugs is being underestimated. "Fuck yeah we can, we can probably can beat you all right now." Their teenage English teacher said to them with newfound confidence and a dangerous-looking grin on his face. This made the angry pomeranian growl aggressively. "Then let's fight," Katsuki said at their teachers. The couple grin, their students were going to learn that they have the best teamwork, even when they were teens.

After a few hours of getting ready and preparing for the battle against the two pros that gotten de-aged, everyone meets at one of the gyms to fight their teenage teachers. They were all in their hero costumes while their teachers only had their support weapons since their hero costumes were too big for them at the moment. The referee was Midnight and the other teachers and classes came to see who's ass were going to get kicked, they all assumed it was going to be Class 1-A except Midnight, Recovery Girl, and Nedzu because they knew them as teens due being friends/old teacher/being the school nurse at the time. Once the students and the gay power couple were ready to fight, Midnight gave them the go signal and the students started to attack their teachers. 

Shouta's and Hizashi's teamwork was flawless, they knew each other's strengths and weaknesses like the back of their hands. They were taking out the class one by one. The first four students to be out were Jirou, Koda, Sato, and Mina from being knocked out by Shouta's punches. Then, the next few students that were out were Sero, Denki, and Ojiro by Hizashi screaming in their ears and Shouta throwing them out of the ring. The next student was their son, Hitoshi, Shouta used his quirk on him before Hitoshi could use his and then Hizashi hits him in the stomach hard. Hitoshi coughs and tries to breathe but his parents showed no mercy, just like Denki, Sero, and Ojiro, he was thrown out of the ring. Tokoyama and Shoji were next, Shouta used his capture weapon on Shoji's arms and yanked him out of the ring before helping Hizashi fight the birb. Toko was knocked out by a surprise attack by his homeroom teacher. 

"Moonbeam! Watch out!" The loud blonde said to his lover as Tsu and Momo tried to attack him. Tsu managed to wrap her tongue around the dark-haired boy but he used it to swing her out of the ring and getting out of it in the process. "Thanks, Sunshine! I could always count on you!" The sleepy teacher said to his partner in crime. Hizashi takes out Momo with a hard kick to the side. Uraraka, Tenya, Yuga, and Kiri tried to get their teachers out of the arena but like the rest of their classmates, they were knocked out. Toru was kinda hard with the fact that she was only invisible and that she took off her gloves and shoes but what the students don't know was that Hizashi can feel any kind of vibration if he focuses hard through the floor because when he was younger and didn't have hearing aids, he would use the feeling of his feet for vibrations to help him control his quirk. Hizashi uses this method to track down the invisible dumb, then signs Shouta where she was coming to attack him. Shouta wrapped his capture weapon around her and made a gasping sound, she didn't know how he knew where she was since he can't see her or use his quirk on her. The Erasure hero yeets her out of the fighting area. 

The last three students were Katsuki, Shouto, and Izuku. The first one out of the three was Katsuki after Hizashi quickly takes him out with his quirk and a knock out punch in the face. Shouta had to use his quirk on Shouto before he could use his fire or ice quirk, Hizashi roundhouse kick him out of the fighting arena. The last student, Izuku trembles with fear and adrenaline. He has seen how amazing the two pros teamwork was. It was flawless and that is what scared him. The green-haired boy had to play smart instead of just rushing into action, but since he was thinking too much, he didn't see Hizashi's fist aiming at his face till it was too late.

The entire class 1-A was defeated, most of the faculty and all of the other students were in shock from the two pros that just gotten de-aged by the Teenage Dream a few hours ago could still fight as pro heroes just like that. They didn't want to be on these two pros bad side or want them to join the dark side. The knocked out and injured students were brought to Recovery Girl. The two teens went to the locker room to change into a sweat-free school uniform.  On the way to the locker room, they couldn't keep their hands or lips to themselves. They just won against 20 superpowered teenagers with just wearing their support items and the school's gym uniform. 

"You did so well, Precious~," Shouta tells him, making the blonde hero blush. "You did too, Kitten." He said to him, making the tired teen blush this time before giving him kisses. The two giggle like a couple of schoolgirls as they entered the locker room to shower and changed. They went to the teachers' dorm and went to their shared room to sleep, they were exhausted. They just went to bed in their boxers and cuddled up before falling into a deep sleep. The next morning, they were back to normal and they were still tangled up in each others' arms, happily, where the two men belonged.
