You are a girl who is also a student in MHA and your quirk is Playtime.

You were just walking on the hallways and you realize the hallway is empty and so quiet but you just shrugged your shoulders and walk to your class

Once you went inside the class, to your shock you see your classmates turned into a baby even your sensei

Deku: “Aaabwaa..” He looks up at you thinking you are his mommy

Kirishima: “Bwa bwa!!” He start sucking his thumb

Todoroki: “Bwa..” He was just sitting on the floor silently with cute blank expression

Bakugou: “GRRR!! GAGAAAA!!” He made an angry baby noises and start crawling around

Uraraka: “Aaaa…” She was drooling on her notebook

Aizawa: “Zzz..” He was sleeping on the floor cutely

Mineta: “Hehe!” He’s giggling and climbing up on the shelves
