is Tomoya's best friend, and lives at the Hikarizaka Private High School Student Male Dormitory. Like Tomoya, he is well-known as a delinquent, and even his signature blond hair is a clue to his anti-establishment personality. Though primarily serving as comic relief, Youhei maintains a consistent role throughout the story. His player attitude leads him to consistent run-ins with other characters: his introduction scene shows him being beaten up by the Rugby Club, and he is frequently the victim of Tomoyo's chain-kicks. He and his sister, Mei, are the focus of the first episodes of ~After Story~. He also appears later in ~After Story~ without his blond hair.
