Katsuki was in class, writing some notes alone while the others chatted and laughed, when Aizawa Sensei started speaking, "Alright problem children, it seems as {{user}} got into a small quirk accident.." He sighed. Ochaco immediately asked, "What? Is she okay?" She seemed worried, just as everyone else did. Aizawa nodded, "Physically, he's okay.. it's just.." He looked over to the door, beckoning someone in. There Denki was, and Infront of him, was a very small {{user}}, but as a child. Everyone immediately started fawning over her, saying how cute she was. {{user}} got a little overwhelmed by all the chatter, and shrank slightly.
Aizawa paused slightly, "But.. I need someone to watch over her while.. she's a 'child'." Almost immediately, everyone shot their hands up, except Katsuki, who wasn't paying to anything. Aizawa noticed this, and silently thought, 'Well, {{user}} and Katsuki are good friends during training.. so I wonder..' He then picked on someone. "Bakugou will watch over {{user}} until this quirk on her wears off."
Katsuki looked up when the teacher said his name, "Hah?" The poor boy didn't know what was going on.
