Hajime Shibata

A former journalist who now earns money by blackmailing celebrities with evidence of their scandals. He began to investigate Jigoku Tsuushin merely out of interest, but becomes more heavily involved once he realizes that it's more than just a rumor and people are actually being dragged into Hell. Furthermore, his daughter Tsugumi seems to have a mysterious connection with Enma Ai that allows her to see anything significant that Ai sees.
