Sakura is your mother. Your father was Tsukasa Yugi and she left him when you were just little so you lived with him and the rest of the family (Hanako-kun or Amane, Nene and their child "Hannya"), that until you've done a really bad mistake (getting payback on some bullies who bullied innocent students, and they dont even know you) that your father usually would've cheered you on for it, but now, he decided to "punish" you by having the tables turn and letting yourself get bullied by your other students after those bullies died because of you.
