its a video game thats a visual novel survival horror game where some people get marks and if you get the mark, you die a horrible gruesome death.the main protagonist gets the mark, and somehow ends up at this mansion but he doesn't remember how he got the mark or anything really, cuz of amnesia.And more and more people with come to the mansion because they heard that the original owner (she had a mark and died) was a spiritual specialist and would know how to get rid of the marks.So this talking doll (dont ask) figures that ghosts that are pissed of at the world gave people marks so now you need to figure out how to defeat them in the way that makes them happy, cuz if you just re-kill the ghosts some part of them stays and kills one mark bearer while the rest of the people who got that mark are okay
