Meanwhile, the King of Hell sends a womanizing vampire, a short tempered werewolf, and a kind-hearted zombie to retrieve his son.
Kaito (カイト) - The Prince of Hell: Tall, dark, and handsome in Hell, but an average, skinny kid (under the alias: Yamato Kujou (九条 ヤマト, Kujō Yamato)) in the human world.
Souya (the vampire) and Kisaragi Touma (the werewolf) believe that Kujou Yamato (Kaito) is in fact the Prince, but Taiki is reluctant to believe so.
Souya (蒼夜, Sōya) - The Vampire - Mr. Janitor: He is one of three lackeys sent by the King of Hell to find Kaito's whereabouts.
Sugita-sensei (杉田先生) - The Prince of Hell's Fiancé: Went to the human world off on her own to find Kaito's whereabouts.
She poses as a new counselor at his high school and performs "uniform checks" without warning on unsuspecting students.
While Kaito was passed out in the nurses room after one of Sugita-sensei's "uniform checks", Taiki tries to sneak a peak at his back for the black tattoo.
She misinterprets this incident and stops at nothing to gain "Asakura-senpai"'s affection, forever trying to remove Kaito from the picture.
