Shiin

"Hey, have you heard about that cursed mark?"

Kazuo Yashiki is a man who has lost his memory and has nothing to tell him why, save for a strange brand on his wrist that represents impending death. His intuition leads him to Kujou Mansion, home of a mysterious talking doll named Mary. Mary explains that the mark represents a spirit's curse. If he and others bearing the mark wish to survive, they must cleanse each spirit's grudge.

But why are these marks appearing now? Who is Yashiki really? And will everybody survive?

Shiin is an adaptation of the 2017 video game of the same title.
