Ai, a name given to him by high school president Ren Ooba, is a bored Grim Reaper who plays his "Sarashi Asobi (Exposing Game)" with Ren when she only had days left to live.
Ren is not his only "plaything" though, as he also extends his powers to 'expose' the true thoughts and emotions of Ren's friends.
