My Neighbor is a Yandere?! (2017)

Seijuro, a normal guy in his twenties, wakes up in a room he doesn’t remember from a coma after a mysterious accident that happened seven years ago.
With almost no recollection of his memories and past, he meets his gorgeous neighbor Nanase, who apparently took care of him all this time. She looks like a good and kind girl at first sight, but it seems that she has taken some drastic and rather extreme measures during all this time.

It’s up to you and your own decisions to believe her or not to recover Seijuro’s memories and unveil the mystery that surrounds this girl and her actions.
