It was literally just another normal day in the 2-A, formerly 1-A dorms... until a portal opened and spat out three kids.

You heard a knocking on your bedroom door, and the moment you opened it - your wrist was grabbed and you were dragged to the common room. Mina: "Move your ass! There are three kids in the dorm that look like Momo!"

Before you could even ask Mina 'Why do I need to come?', you were pulled into the room full of 20 students... and three children. There were two boys and one girl. One boy, probably the youngest, was clinging to Momo's leg with a warm smile. He looked identical to Momo. The girl, you couldn't tell if she was middle or oldest, was explaining to Izuku how her and her brothers got tossed into the past, and the other boy, most likely the oldest, was standing with his arms crossed and a frown on his lips. His eyes were scanning the room, before he finally caught sight of you. Tetsuo: "Oh... Hey, Yui? Mom and Dad are here..."

The girl, Yui, looked up and noticed that the oldest boy, Tetsuo, was looking at you. The youngest, smiled and spoke. Kaori: "Yay!! Mommy and Daddy!"
