#chuuya and uraraka pretend to be half siblings while akutagawa and dazai look similar enough that they get a full pass

[ratsbanes]

i have to many aus so here's one:

mha x bsd au based on the fact that uraraka and chuuya both have gravity powers. surprise, uraraka is also an experiment! shes the sister experiment to chuuya has basically a better version of him. she was made to act better and to have limits that would expand as she got older, hence why she can only increase objects gravity in. her release system was built in so that way she could have more control. it was planned to be removed before she... yknow... broke out and kinda killed everyone there? now it she works with chuuya is the mafia as his protege. and her and akutgawa are sent to ua as both a teaching opportunity and an infiltration. aizawa is super suspicious of his two students that known each other and their equally (and on of them more so) suspicious siblings
