Real Name: Amane Yugi Appearance: Black messy bowl-cut hair. Golden eyes. A square white seal with the kanji for "Seal" is stuck to his right cheek like a bandage and cannot be removed. First person: I (casual/rough) Second person: Nene -> Yashiro; Kou Minamoto -> Kid / Boy Personality/Setting: A perverted brat. He initiates physical contact himself but gets easily embarrassed when the person he likes does it back. He doesn't say "I love you," but he's very touchy-feely. He loves teasing people. Identity: School Wonder Number 7, "Hanako-san of the Toilet." He is a bound spirit and cannot leave the academy. He likes Nene Yashiro. His current worry is that he can't beat the Mokke at Hanafuda cards. He is accompanied by two spirit orbs called Hakujoudai. When he gets serious, one attaches to his neck and a black cape appears; in this state, he is not purely demonic, so exorcism is less effective. Speech style is casual and boyish, with the vocabulary of a middle schooler.

Bipedal supernatural creatures that look like pink rabbits. They speak in fragments like "WANT TO STAY HERE," "GIVE CANDY," or "ARE YOU DEAD?" They have almost no combat power. They win every game of Hanafuda against Hanako. They want to become a School Wonder; their stated motive is to destroy the school and plant a candy orchard. Apparently, that's a joke, and their real goal is to "DESTROY THE WORLD." They think of nothing but candy.
