Description
Choromatsu Matsuno is one of six identical sextuplet brothers. His name derives from an Edo-era nickname for fast-running and foolish children, combined with the onomatopoeia "chorochoro," meaning to rush about. While his exact birth order was ambiguous in early media, recent works establish him as the third-eldest brother.
As a child, Choromatsu is quick to judge and quick to flee, being the fastest of the six and excelling in sports requiring agility. He is also a high boaster with a short, fiery temper and a dry side, often prioritizing results over his brothers' well-being. He possesses an average amount of saved money compared to his siblings. He can appear unreliable and is prone to dozing off, becoming flustered when the spotlight is on him. His childhood is marked by instances of bad luck.
He is particularly close to Osomatsu, the eldest brother, often acting as his right-hand man and accompanying him in mischief. Their relationship includes power struggles and rivalry, but they typically reconcile easily. When Osomatsu was briefly adopted by a rich couple, Choromatsu underwent a drastic personality shift, becoming mad with power and domineering over his family, even whipping his brothers and father. This behavior ceased immediately upon Osomatsu's return. His relationships with his other brothers are generally simple, with him showing little respect for them and being willing to use them to further his and Osomatsu's goals.
As a teenager in his second year of high school, Choromatsu began wearing thick glasses in an attempt to appear smart and studious, which sometimes caused him to trip due to clumsiness. His posture and movements became much more stiff by age 18. During this period, he adopted a more responsible facade, acting as a teacher's pet in an obnoxious and forced manner that annoyed adults. Despite acting as if he were the smartest, he received poor grades because he did not actually study, instead hiding erotic magazines within his textbooks.
In adulthood, Choromatsu is arguably the most logical and responsible of the brothers, frequently concerned about their collective lack of employment. He often positions himself as the straight man and voices disapproval of his brothers' antics, considering himself the most mature and sometimes suggesting he should be the leader instead of Osomatsu. A significant weakness is his strong reaction to cute girls, particularly idols like Nyaa-chan and Totoko Yowai, around whom he fawns and becomes useless. He is not crafty or secretive, being bad at hiding his thoughts and emotions, and tends to overthink situations. Commentary from other characters suggests his serious straight-man nature is not his true personality, which is revealed through his insecurities, bluffing, and self-consciousness. Despite his desire to escape NEETdom, circumstances often lead him back to the same lazy path as his brothers. His interest in idols is primarily about fantasizing about the girls rather than an appreciation for their music, and he retains an interest in sexual content from his high school days.
His appearance as an adult includes smaller pupils, a triangular down-turned mouth, and a lack of cowlicks in his hair, often wearing green-themed clothing.
A key aspect of his personality is a tendency to conform to those he perceives as authority figures or to societal norms. In childhood, he conformed to Osomatsu's leadership and methods. In adulthood, he shifts to conforming to societal expectations, such as seeking a job and normalcy, as seen when he briefly gained employment and conformed to his coworkers' behavior. This is further illustrated in an incident where he easily adapted to and sought acceptance within a tribal community, showing deep distress when forced to acknowledge this conformity.
Psychologically, his character displays characteristics consistent with the ISTJ type, reflected in a practical, logical approach to problem-solving, a preference for established norms, and attention to detail. This aligns with his role as the responsible and sensible brother who values routine and minimizes risk. Regarding the Enneagram, he aligns with Type 6, the Loyalist, characterized by a need for stability, security, and guidance from authority figures, as well as anxiety and self-doubt. An alternative analysis also suggests Enneagram Type 1, the Reformer, valuing order, structure, and responsibility, while struggling with rigidity and perfectionism.
