Hajime Nojima is a first-year Mechanical Engineering student at Izu University and a classmate of Iori Kitahara. Tall and self-proclaimed handsome, he sports long black hair with two distinct bangs framing his face, black eyes, and consistently wears black glasses. Nojima cultivates a self-styled playboy persona, attempting to project charisma, though his efforts often register as unconvincing or lame, resulting in minimal romantic success. He operates within the university's social circle connected to the main characters. The character appears across the franchise's manga, anime series, live-action film, and the upcoming 10th-anniversary stage play, where Arihiro Matsunaga portrays him.
