Yoshinobu Kubota starts out as a timid classmate of Sakamoto's, frequently taken advantage of by those around him. Guided by Sakamoto's quiet but powerful influence, he musters the courage to take on a part-time job at a fast-food restaurant, gradually building self-reliance and reclaiming his sense of dignity. His near-obsessive dedication to his hairstyle serves as a quirky yet endearing character trait. Though unassuming in appearance, Kubota undergoes one of the most remarkable personal transformations in the series, and the bond he forges with Sakamoto stands as one of its most heartfelt relationships.
