Description
Choromatsu Matsuno is the third-born of the Matsuno sextuplets. His name derives from an Edo-era term for foolish, fast-running children and the onomatopoeia "chorochoro" (to rush), reflecting his inherent agility. As a child, he appeared physically identical to his brothers but later became linked to the color green. He demonstrated quick-witted yet impulsive tendencies, often summarized as "quick to judge and quick to flee." While excelling in agility-based sports, he prioritized results over his brothers' safety and displayed a short temper. He frequently partnered with Osomatsu, though their dynamic featured power struggles and rivalries—particularly when Osomatsu sabotaged others or Choromatsu pursued dominance. He showed unreliability in instances like dozing during tasks and encountered misfortunes such as being urinated on by an elephant during an African safari.
In high school, he adopted thick glasses to appear studious but maintained poor grades by concealing erotic magazines inside textbooks. His posture grew rigid, and he avoided cowlicks in his hair. This persona included forced obsequiousness toward authority figures. A pivotal pep talk from his adult self during this time influenced his later trajectory toward perceived responsibility.
As an adult, he positions himself as the most logical brother and primary "straight man" in comedic exchanges. He voices concerns over the brothers' unemployment and advocates to replace Osomatsu as leader. However, his self-proclaimed maturity clashes with obsessive fixations on cute girls like Totoko Yowai and idol Nyaa-chan—admitting his interest stems from fantasy rather than music. He fails to mask emotions, overthinks situations, and bluffs frequently, which others interpret as insecurity. Despite sporadic reform attempts, he consistently lapses into NEET habits. His adolescent interest in erotic material endures, manifesting in actions like peeking under dolls' skirts.
His relationship with Osomatsu evolved from childhood alliances and competitions, including an episode where Choromatsu temporarily seized household control during Osomatsu's absence, only to collapse upon his return. Over 30 manga chapters chronicled their dynamic, spanning collaborative mischief to hostility—such as Choromatsu tampering with Osomatsu’s map during a life-threatening crisis. In a dystopian future arc, Choromatsu regressed to a childlike state after suffering psychological damage from Osomatsu’s disappearance.
