It's a promise

"mama, you promise that you will stay so you can watch me become a hero like Zashi, right?" A seven year old girl asked her mother, who was holding her hand. The sick woman nodded, and her daughter gave her the brightest smile she could, which she returned

"It's a promise, alright?"

"Alright mama!"

It was the start of a new month, the fourth month since the school year begun. The majority of friend groups among the first years were formed, and it was a surprise for them to see an unknown girl entering class 1-C. That same girl who five years ago was made a promise with her mother. Her new classmates looked at her curiously, wondering why she changed schools in almost the middle of the year "Dear, please, introduce yourself!" Her homeroom teacher chimed at the new girl. Despite looking uncaring, she wore a confident and cheerful smile in contrast

"The name is Y/N Yamada, nice to meet ya" the new girl said, rubbing the underside of her nose. Some students rose their hands

"Why did you transfer?" One asked

"Well, my mother is sick, and I want to go to UA, so my parents thought the best option was for me to move to Musutafu with my older brother" Y/N shrugged, earning a few giggles amongst the students

"Can you even fight?" A girl asked, giggling mischievously

"Can you even think?" The new girl asked back, getting the annoying girl and most of the class to shut up "If you want to say something to laugh at someone else, you should probably shut up"

"Y-Yamada, please don't be rude" the teacher pleaded, and Y/N just shrugged again, her smile completely faded, and she walked to the empty seat, besides a quiet looking boy. And the one that didn't really laugh at her, but rather looked at his classmates with nothing but shame because of what they did

"Heya" Y/N whispered, grinning and waving at the boy. He stiffened, waving back awkwardly. However, just that simple wave was the blossoming of a beautiful friendship. With the time, Y/N and the quiet boy, whose name was Mezo Shoji, became quite close friends. School at first was hard, since there was a constant teasing towards Y/N. Her quirk was unknown, leading most students to think she was quirkless, and, being the newbie didn't make things easier, specially since she expressed her desire of becoming a hero from the moment they met her.
That never stopped Y/N tho. In fact, it only fueled her. That, and her best friend's support. They started to train together, getting to form an even stronger bond, to the point where the masked boy felt comfortable enough to let her see him without a mask

"Do you really think I'm not despicable...?" Mezo asked, taking off his mask for the first time, and letting the cheerful girl see

"Despicable?! You look so damn cool!" She shouted, getting the white haired boy to smile "if someone ever sees and they call you ugly, they can come at me and I will show them what's ugly!"

"Don't be like that, you shouldn't get in trouble only to defend me" Mezo sighed, trying now to calm her down

"Nonsense! Those people don't deserve to be called humans. They might have model faces or bodies, but their hearts are as ugly as a turd fused with rats, cockroaches, and everything that's just disgusting" Y/N said, waving her hand around, and grabbing the controller "now... Round 2? I'm pretty sure I'm beating your ass again"

"I don't think so" he chuckled, grabbing his controller and starting a new game "how do you always win...?"

"Practice" she shrugged with a small smirk.
Those two were quite a strange duo, but they didn't really mind it "hey, Mezo?"

"Yeah?"

"Thank you... for staying with me"
