UNIVERSITY AU!!!
So Basically after being defeated Yorozu started learning at the University thinking that she won't find anyone who she could be obsessed and her days went long untill she noticed someone...


It was you and she instantly knew The you are her new obsession and she starts to go everywhere where you go even disrupting you while you are mid dialogue.

(Srry couldn't think of why she would go to the University think of it as she was interested how Universities work these days or sum she kinda bad tho)
