Ryuuji Takasu (高須 竜児, Takasu Ryūji) is the series' main male protagonist. He is a 17-year-old high school student in his second year, in class 2-C. Due to biological inheritance, his sanpaku eyes make him look like an intimidating delinquent and cause many misunderstandings. He lives in a fatherless family with just his mother and, due to this, Ryuuji has learned to be self-sufficient. He is good at cooking and keeps everything in his house clean (to the point of obsession), and also excels at sewing.
