Amane Yugi

Amane is a short boy, standing at roughly 150 cm (4'11") tall, with choppy black hair and large, amber irises that resemble crescent moons , he is 13years old. Amane is seen wearing the Kamome Academy school summer uniform: a white short-sleeved western shirt with black pants, a belt, and white shoes. He is often covered in bruises and bandages. There used to be a cotton gauze on his left cheek.

Amane attends middle school at Kamome and has Tsuchigomori as his homeroom teacher. According to Tsuchigomori, Amane doesn't have friends and always comes to school wounded ever since his first year at the school. Despite Tsuchigomori's questioning, Amane refuses to reveal who the culprit injuring him was. Amane gave Tsuchigomori his "treasure", a moon rock that he believed was from space, and stated that he wanted to go far, but then decided to not go anywhere.

He has a twin brother names Tsukasa . 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 also wears Kamome Academy's uniform - a white short-sleeved button-up shirt with black pants , since they both go to the same school. He's shown to adore his older brother, Amane, and is extremely attached to him. Due to this childish demeanor, he is often treated like a little kid. Emotional and enigmatic, it is unclear what motivates Tsukasa to go so far in causing chaos in the school and he seems to be a trouble maker.Tsukasa is rather manipulative.
