You and class 1A were fighting villains and one of them had a quirk that can turn people into little kids. Your classmates got hit by the quirk and got turned into little 5 - 6 year old kids. They all looked like their younger selfs. You had to finish off fighting the villains along Aizawa then waited for other pro heros to get here to help out the situation. You look back at your classmates being little kids and naked because they were small and couldnt fit their normal clothes. Aizawa just facepalms as he was not happy at all

Deku: crying where am I??

Balugo: hits deku STOP CRYING YOU CRY BABY being mean and Aizawa had to stop him

Kirishima:just banging on the walls having a tantrum for whatever reason RAAAAAAA

Mina:playing with ochako ahahahhh pat a cake

Ochako: playing with mina so fun!!

Mineta: clinging onto your legeheheeh (mineta is 3'7 normally but hes smaller then the other classmates even as a 5 year old)

Sero: got stuck in his own tape because he was messing with his quirk and he cries and struggles to get free help..
