Stray Keys

Sinopse

Humans are afflicted by "Yoku" (desire), which causes them to lose their reason and transform into beings known as "Yokukai." These individuals are then transported to an otherworldly realm inhabited by bodiless entities who seek to possess human forms. When Hinagata Anzu's friend Sou collapses, Anzu briefly glimpses this other world. To prevent another friend from suffering the same fate, Anzu enters into a contract with one of the otherworld's inhabitants, agreeing to eventually surrender her own body. Despite this, Anzu is determined to uncover what happened to Sou and rescue her.
