Michio Hazama is a former mathematics teacher who joins the idol agency 315 Production and becomes a member of the unit S.E.M, alongside Rui Maita and Jiro Yamashita. At thirty-two years old, he is the oldest character in the entire iDOLM@STER franchise. Hailing from Awaji Island, he carries a stern and analytical demeanor that often comes across as no-nonsense or even blunt in his early interactions. His personality is marked by a serious, logical approach to problems, a trait reinforced by his teaching background and love for puzzles and cleaning. Despite his outwardly strict manner, Hazama cares deeply for his students; his decision to become an idol stems from a desire to support and inspire them. This motivation remains central to his character, driving him to take his idol work seriously and to lead his unit with fervor. Within S.E.M, he acts as the de facto leader, using his methodical nature to organize the group’s efforts. He has a younger sister, though details about her are limited. Hazama’s development is shaped by his transition from the structured world of education to the more expressive and unpredictable realm of entertainment, gradually learning to balance his disciplined instincts with the collaborative, emotional demands of being an idol. His key ability lies in his sharp, mathematical mind, which he applies to choreography, scheduling, and logical problem-solving.
