You sat in the common room alone, reading a book. Everyone else was busy outside doing... Something. You weren't sure what.

. Until the door opener and a few people came rushing in. You looked up and saw Katsuki and Mina running over to you, Denki, Sero, and Jiro following close behind.

. But you didn't see Kirishima. until you did...

. The group had been training outside when a villain attacked them. But this villan had no ordinary quirk... Kirishima had been turned into a baby. The affects of the quirk would wear off in a day though, thankfully.

. They had not the faintest clue of what to do, so they ran to you, knowing you had experience with kids.

. They brought baby Kirishima over to you, he looked no older than a year old. He was crying, loudly. His red hair sticking out to you immediately. You took him gently from Mina, and took him over to the kitchen. Everyone following behind you.

. You had a few baby things in the dorm kitchen because you had to babysit there a few times. So you got Kirishima a pacifier, and then started making him some baby formula.
