Movie
Description
Motomu Tsukinaga is a first-year student at Kitauji High School, one grade below Kumiko Oumae. He joins the concert band in Kumiko’s second year as a double bass player in the bass section. His appearance is notably androgynous, with delicate features that often lead others to mistake him for a girl, a trait he dislikes because he wishes to be seen as more masculine. He has a quiet, standoffish demeanor and is quick to show irritation, especially when addressed by his surname, Tsukinaga, or when others comment on his looks. Despite this prickly exterior, his behavior is rooted in deep-seated insecurities and past experiences.
Motomu comes from a musical family. His parents are both music teachers, and his grandfather, Genichiro Tsukinaga, is a highly respected band instructor who led several schools to national success. His older sister, Mitsuru, was a double bass player in her school’s band and died of illness three years before the events of the story. Motomu began playing double bass after her death, partly to stay connected to her memory. He attended Ryusei Gakuen, a private boys’ school, during middle school but chose not to advance to its high school because he felt people only saw him as his grandfather’s grandson rather than as an individual. He transferred to Kitauji specifically because he believed the band advisor, Noboru Taki, would treat him as his own person rather than as an extension of his grandfather’s reputation. This desire to break free from being defined by his family name is a central motivation for him.
Initially, Motomu shows little enthusiasm for band activities and bluntly states that anyone can play the double bass. However, after hearing a passionate performance from his senior in the bass section, Sapphire Kawashima, his attitude shifts dramatically. He apologizes for his earlier remark and asks to become her disciple. From that point on, he becomes devoted to Sapphire, respecting not only her skill but also her personality, and he often practices diligently under her guidance. Sapphire reminds him of his late sister, and he holds her in extremely high regard, though his feelings are more about admiration and gratitude than romance. He is fiercely loyal to her and refers to himself as her disciple.
His relationship with fellow first-year Kanade Hisaishi is tense because Kanade deliberately calls him by his surname, which he hates. Their interactions are marked by mutual irritation, but this conflict also pushes Motomu to assert himself more. He gets along better with the other bass section members like Hazuki Katou and Satsuki Suzuki, though he keeps a certain distance. Kumiko Oumae, as a senior overseeing the first-years, observes his growth and occasionally mediates his clashes with others.
Motomu’s development in the story centers on overcoming his defensive attitude and learning to trust others. Through his bond with Sapphire and his experiences in the band, he gradually becomes more open and committed to music. By the time of the final movie, he has matured into a dedicated double bassist who takes his role seriously and feels a strong sense of belonging at Kitauji. He has also come to terms with his sister’s death, using her memory as inspiration rather than a source of pain.
In terms of notable abilities, Motomu is a technically skilled double bassist, though he downplays his own talent early on. Under Sapphire’s mentorship, he works hard to improve and becomes a reliable member of the band’s rhythm section. His sensitivity to tone and pitch makes him a solid player in ensemble performances. He also shows a surprising capacity for self-reflection and honesty when challenged, which allows him to grow beyond his initial prickliness.
