Description
Osomatsu Matsuno, the eldest of six identical brothers born on May 24, positions himself as the group's self-proclaimed leader. His name, derived from the Japanese word "osomatsu" (お粗末) meaning "lame" or "ill-prepared," reflects his unreliability despite this role. As the strongest fighter among the sextuplets, he leads physical confrontations, especially when defending his brothers. His leadership is frequently undercut by impulsiveness and a lack of foresight, causing resentment from his siblings over his inconsistent dependability. He shares a close partnership with the third brother, Choromatsu, frequently collaborating on schemes and adventures, though this dynamic sometimes sparks conflicts with the others.
In childhood depictions as 10-year-old fifth-graders, Osomatsu and his brothers engage in constant mischief, exploiting their identical looks to confuse others, including their parents, during pranks. Osomatsu exhibits a blunt, tactless personality devoid of social skills and possesses a notable love for food, especially donuts. He occasionally adopts drag disguises, either strategically or by personal choice, such as being forced into a girls' swimsuit by Totoko at the beach. His adventures include surreal escapades, like being abducted by aliens with Choromatsu or paving a road to restore a blocked shortcut.
In later manga chapters and the 1988 anime, Osomatsu and his brothers are gradually overshadowed by rising supporting characters like Iyami and Chibita, reducing the sextuplets to secondary roles and diminishing Osomatsu's prominence. A "what-if" story, "Osomatsu-kun Grows Up," portrays his adult life as a balding, unmarried salaryman frequenting a bar run by Iyami, contrasting with his brothers' settled family lives and emphasizing his loneliness and lack of growth.
The 2015 reboot reimagines Osomatsu as a 20-year-old NEET who retains his leadership role but embodies laziness and escapism. He spends his days gambling on pachinko and horse racing, dresses in red, and remains financially dependent on his parents. This version amplifies his earlier irresponsibility into chronic avoidance of adulthood, though he occasionally displays fleeting moments of ambition or camaraderie. His character design and personality consistently highlight his status as the eldest, his combative nature, and his flawed yet central role in the sextuplets' dynamic.
