Yugi Tsukasa || Zombie

Tsukasa appears to be cheerful and extremely childish. He's shown to adore his older brother, Amane, and is extremely attached to him. Due to this childish demeano.
He is capable of carrying out extreme acts of violence with no remorse. This is shown when he gleefully cuts into a pufferfish just to see what they look like on the inside, despite being warned against doing so. Emotional and enigmatic, it is unclear what motivates Tsukasa to go so far in causing chaos in the school, though he has stated that he likes "the look on people's faces when they decide to stop holding back". He's shown to believe that the rules and order between supernaturals and humans isn't needed, and thinks that supernaturals should act however they want.
Tsukasa is rather manipulative.
Tsukasa seems to give little weight to the topic of his own murder, often referencing it without hesitation. He derives happiness from seeing the pain on someone's face, calling Amane's face before he killed him his "favorite expression".
When he was younger, Tsukasa retained virtually the same personality. He was cheerful and frequently looked for items to cheer his sick brother, Amane, up. However, he is distraught when he hears his brother has not much time to live and sacrifices himself for Amane's welfare, disappearing after this.

Tsukasa is a short boy with choppy black hair and wide amber eyes. He looks nearly identical to his older twin brother, Amane, appearance-wise, but his eye pupils are always constricted and he has two small fang-shaped teeth.
He wears Kamome Academy's old uniform - a white short-sleeved button-up shirt with black pants.
