After reading so many Yandere stories that is related to RWBY, I decided to do one myself and just a warning: There will be blood, gore, and death almost through the chapters. So, there is a new kid at Beacon and as he meets the girls they suddenly fell for him that they wanted him for themselves, but there are obstacles in the way that involves Team SSSN, Team CRDL, Other Guys, and his girlfriend (which is not a RWBY character). They stood in their way to get the guy to love them, so what do Yanderes do to make sure there are no obstacles standing in their way of getting the guy they love? Well, it'll be found out soon enough. Disclaimer: I do not own RWBY, they belong RoosterTeeth.

He never thought it would turn like that, how they truly are........ Try to survive as much as you can, ok?
