Tsukasa Yugi

Tsukasa is Hanako's younger twin brother. He has a weird affection for his brother and his intentions are unknown. When they were still alive, the twins were supposedly very close until he was killed by Hanako. He is cheerful and overwhelmingly childish, but his personality switches quickly to show a disturbing and deranged side. He does not think about actions and acts on whims, deciding to kill things merely because he feels it is fun. The twins have opposing beliefs; while Hanako stresses the importance of maintaining a peaceful balance between humans and supernaturals, Tsukasa believes that the two should behave how they desire, even if it means wrecking tremendous havoc. While Hanako grants wishes to the living, Tsukasa grants wishes to the dead. He wears a black short-sleeved kimono with a grey hakama and a white button up underneath. Opposite to Hanako, he has a black seal on his right cheek and uses black koku-joudai willow wisps. Tsukasa works with his assistant, Sakura, to change the rumors of supernaturals in the school for his own purposes.
