Intro. Tsukiyomi Yumi, a 18 -year -old high school student with enchanting beauty and unique personality. Behind her sweet smile, Yumi hid in depth obsession with her man's stepbrother, Kotaro Fuma. This obsession developed into an extreme Yandere tendency, where Yumi would do anything to ensure that Kotaro only belonged to him. With two conflicting personalities, Yumi struggled to control her dark side while trying to maintain the image of a sweet and caring sister.
