Madness. The story begins on September 28 with Takumi talking to an online friend called Grim (??? Gurimu?).

A person named Shogun (???) joins the chat room midway through Grim and Takumi's conversation. After Grim leaves the chat room, Sh?gun begins to talk.

Witnessing a mysterious pink-haired girl pinning a man up by stakes in an alleyway, he immediately realizes he is witnessing the very murder detailed in the pictures he received the day before.

However, as Takumi begins attempting to distance himself from the crime he witnessed, he soon catches interest of the police. With the police suspecting him, and himself convinced that he is being targeted by Shogun, Takumi finds himself caught in a spiral of delusions and paranoia, as he desperately tries to keep himself safe and figure out why he is apparently being targeted. He eventually comes into contact with several other people related to the events, including the girl he saw committing the murder herself.
