Hiyama, Takao

火山高夫

Takao Hiyama is a teacher at Yuki's school and the serial killer reported in the area. Little is known about Takao's character, as he only has four lines of dialogue in the series, all concerning the discovery of and surprise at Yukiteru. He is the owner of the Third diary. His "Killer" diary records the location of his next intended victim. It is a useful diary if one knows the true identities of the other diary holders and wishes to take the offensive in the game, but it does little in any other regard.
Takao wears a heavy trench coat, complete with a hat and mask that hide his identity when stalking prey, and carries a large machete as his weapon of choice.
He is named after Vulcan, the Roman god of blacksmithing.
