Amane had no friends, he regularly skipped classes and his grades left much to be desired, despite the fact that he apparently had extensive knowledge of the natural sciences, in particular astronomy. In addition, Amane came to school every day with bruises and abrasions all over his body, and according to his teacher Tsuchigomori, this was a common occurrence from the very beginning of his schooling. Yugi was regularly abused, but despite the pain he suffered, Amane never admitted who he was.
