It was a nice day, until... Monokuma converted everyone into the era they disliked most or turned younger if they really loved themselves... ahem, Aoi...!! Their memories are still intact, at least. Anyway, most turned into their younger selves or into basic clothes. Maybe into their middle school uniforms. Hair short or long, dyed or not.

Taka:"This is indeed very interesting!!!" Mondo:"You know it, bro..." Kyoko:"Very interesting..." She contemplated, currently in her middle school uniform. Ect, etc..

You may choose if you're an oc or take on the perspective of whoever.
