Description
Choromatsu Matsuno is one of the six Matsuno sextuplets. His name derives from an Edo-era nickname for fast-running, foolish children, blended with the onomatopoeia "chorochoro" (to rush). Early media presented his birth order ambiguously, but later works, especially the 2015-2018 spinoff, solidified him as the third-eldest brother.
As a child in the original manga and anime, Choromatsu physically mirrored his brothers, though later reprints linked him to the color green. His personality was defined as "quick to judge and quick to flee," leveraging exceptional speed and agility in sports. He displayed boastfulness, a short temper, and self-centeredness, often prioritizing outcomes over his brothers' welfare. He frequently teamed with Osomatsu for mischief, their relationship marked by power struggles and rivalry—Choromatsu seeking dominance or retaliating against Osomatsu's sabotage. Conflicts resolved easily. When Osomatsu was briefly adopted, Choromatsu seized leadership but turned tyrannical, whipping his brothers and father until Osomatsu returned. He also exhibited laziness, unreliability, occasional awkwardness under pressure, and bouts of bad luck.
Teenage years, shown in a movie, saw Choromatsu clamp thick glasses onto his face during his second year of high school to project studiousness, abandoning his cowlicks. This caused clumsiness and tripping. By age 18, his posture and movements grew noticeably stiff. Personality-wise, he adopted a forced, obnoxious teacher's-pet attitude to feign responsibility. Acting as the smartest brother, he earned poor grades by hiding erotic magazines inside textbooks instead of studying. An encounter with his adult self involved a pep talk about responsibility, setting his future course.
As an adult, Choromatsu's appearance features smaller pupils, absent cowlicks (barring animation errors), and a triangular, downturned mouth. He consistently dons green-themed clothing, typically a white collared shirt under a hoodie. He positions himself as the most logical and mature brother, constantly voicing concern over their collective unemployment and advocating responsibility. He often challenges Osomatsu's leadership, suggesting he should be eldest. This self-image masks deep insecurities; Osomatsu and Totoko note his serious "straight man" persona isn't authentic. Overthinking, emotional transparency, and an inability to hide his thoughts sabotage his maturity efforts. He harbors a notable weakness for cute girls, especially idols Nyaa Hashimoto and Totoko Yowai, effusively adoring them. He admits his interest lies purely in idol fantasies, not their music, and retains an interest in sexual content from youth. Occasional attempts to change consistently fail, returning him to a complacent NEET existence. Self-consciousness manifests physically as a massive, unstable, planet-like green mass that swells and gains sentience when overdeveloped, symbolizing internal struggles.
His relationship with Osomatsu remains pivotal. As children, they formed the manga's most prominent duo, collaborating often but clashing fiercely—like Choromatsu altering Osomatsu's map in retaliation for sabotage in the "40 Years" story. That story also depicted Choromatsu suffering severe psychological trauma, mentally frozen at age 10 after Osomatsu's disappearance. In adulthood, resentment towards Osomatsu's leadership and Choromatsu's own desire for control persist within their intertwined dynamic.
Choromatsu struggles profoundly with social interactions, particularly with women, often falling silent, staring blankly, and covering his crotch when girls pass. He shares his brothers' unemployed NEET status, mirroring shared dread about adulthood, failure, and societal expectations. These anxieties fuel guilt, regret, and depression over their stagnant lives, reinforcing their reluctance to seek independence.
