Shogun

Shogun is a mysterious person that Takumi meets during a chatting session. He sends gore pictures relating to the New Generation incident to Takumi, the equation "fun^10xint^40=Ir2", and the phrase "Whose eyes are those eyes?", which Takumi often used. This event gives Takumi paranoia throughout the story, thinking that Shogun is spying on him and trying to kill him.
