Ryūsei is a third-year student with a distinct cross-shaped scar over his left eye. He served as the gang leader of the school's delinquents before Omi took over his position. In reality, he is a bear spirit. In the fourth volume, he graduates from high school but soon changes his name to Suisei Kumada (Kumada Suisei?) and restarts high school as a first-year student.
