Description
Jiro Yamashita is a 30-year-old former high school science teacher who transitions into the entertainment industry as a member of the idol unit S.E.M, where he represents the science component of the group's name. Standing at 185 centimeters tall with a slender build, his appearance often belies his age and profession; he typically keeps his brown hair styled with bangs covering one eye, though he will sweep them aside for formal stage performances. Hailing from Ishikawa Prefecture and born on September 1st, his hobbies include visiting cat cafes and following horse racing, while his special skill is performing radio calisthenics.
Unlike the passionate and idealistic reasons many have for becoming an idol, Jiro's motivation is initially purely financial. He openly admits that he was drawn to the career because of the impression that idols earn substantial amounts of money, viewing it as a lucrative side job. This pragmatic, almost cynical outlook is a core part of his demeanor. He frequently refers to himself as an old man or an uncle, adopting a lax and self-deprecating attitude that masks a more complex inner world. Despite his occasional claims of only caring about wealth, he possesses a kind heart and several soft spots that he becomes noticeably bashful about when they are acknowledged by others. For instance, he has been shown secretly making time in a packed schedule to watch a young fan's baseball game, only to hide behind a newspaper when spotted.
In his role within the story, Jiro was recruited by his fellow teacher, Michio Hazama, who shared his dream of becoming an idol. Reluctant at first, Jiro agreed after he and another colleague, Rui Maita, were enticed by the potential earnings. This trio of former educators formed S.E.M, creating a dynamic where Jiro often acts as the weary, grounded counterpoint to the energetic enthusiasm of his teammates. His relationships with them are central to his character arc. He lives next door to Rui, who frequently visits his apartment, and Jiro is noted to be a good cook after living alone for a long time. Meanwhile, Michio, who is actually older than Jiro, often scolds him for his lax habits, such as using the school's science equipment to brew his coffee. Jiro's relationships extend beyond his unit as well; he has formed bonds over shared drinks with characters from other branches of the franchise, finding camaraderie as fellow adults in a young industry.
Jiro's development is a gradual process of finding self-worth and genuine passion beyond a paycheck. Initially plagued by a lack of confidence and frequent self-deprecating comments about his age and suitability for the idol lifestyle, he experiences a significant turning point. During the first 315 Production election, his modest campaign plea asking if an old man like him could even participate resonated strongly with fans, and he ultimately secured an impressive second-place finish. This external validation, combined with witnessing the hard work of those around him, slowly chips away at his cynical exterior. He begins to awaken to a sense of pride in his work and a growing enthusiasm for the idol profession itself, moving beyond his initial mercenary motivations.
Despite his self-professed lack of grace, Jiro possesses notable abilities that make him a valuable idol. He is recognized as having very strong singing skills and serves as a key vocalist for S.E.M. However, this is balanced by a distinct lack of athleticism, as he struggles with dance routines and physical exertion, requiring extra training to keep up with the physical demands of performances. His personal life is marked by a quiet solitude; his parents have both passed away, and he does not maintain close ties with his extended family, which adds a layer of poignancy to the new family he finds within his idol group.
