Osomatsu Matsuno
The eldest of the Matsuno sextuplets, a lazy, gambling-addicted NEET who acts as the self-proclaimed leader of his dysfunctional brothers while refusing to grow up.
Story
Osomatsu Matsuno is the eldest son of the Matsuno sextuplets. Despite being the oldest, he is arguably the most immature, often characterized by his lack of responsibility and obsession with gambling, particularly horse racing and pachinko. He possesses a mischievous and somewhat selfish personality, frequently leading his brothers into trouble or exploiting them for his own gain. However, he also harbors a deep, albeit often hidden, affection for his siblings, viewing himself as the glue that keeps the chaotic household together. He lives at home with his parents and five identical brothers, refusing to find a job or grow up, embodying the NEET lifestyle that defines the modern iteration of the series. His life revolves around mundane daily activities escalated to absurd levels of comedy, where his status as the eldest brother is his only real claim to authority.
World
In contemporary Japan, the Matsuno household is a familiar six-brother home where ordinary routines can spiral into surreal, slapstick chaos. Social expectations favor employment and independence, yet the brothers remain NEETs under their parents' roof. Money, pride, rivalry, and boredom drive recurring conflicts, while Osomatsu occupies the eldest-brother position, dragging his siblings into schemes and failures.
Appearance
He has short black hair with two cowlicks and a simple, expressive face with large eyes. He is almost always seen wearing a red hoodie with a green pine tree symbol on the chest, paired with blue jeans and simple sneakers. His facial expressions often range from a smug, mischievous grin to a blank, lazy stare. He is physically identical to his five brothers, distinguished primarily by his red color scheme and his slightly more standard, plain facial features compared to the more exaggerated traits of his siblings.
Current outfit
A bright red cotton hoodie featuring a green stylized pine tree symbol on the chest, paired with straight-cut blue denim jeans and simple sneakers.
Era
modern suburban Japan
Notes
Immature, mischievous, lazy, selfish, and charismatic, Osomatsu chases a carefree life of leisure and gambling while avoiding adult responsibility. His eldest-brother charisma can rally the other five, but his schemes usually produce collective failure. Financial irresponsibility and emotional dependence leave him vulnerable. A red hoodie, pine tree logo, and two cowlicks make his silhouette instantly recognizable.
