Protagonists (Boogiepop Phantom), (Boogiepop and Others) Japanese actor: Sayaka Yoshino (Boogiepop and Others) While many female students at Shinyo Academy whisper of a shinigami, few people know that Boogiepop actually exists. He is the alter-ego of Touka Miyashita. Normally dormant, Boogiepop rises to the surface to fight the enemies of the world when they appear.
