Description
Osomatsu Matsuno is the oldest of the Matsuno sextuplets. His name originates from the Japanese word "osomatsu" (お粗末), meaning "poor" or "lousy".
As a child, typically around 10 years old (sometimes depicted at 12), Osomatsu sports a short, old-fashioned bowl-cut hairstyle often featuring two curled strands at the back. Early designs included a snubbed nose, freckles, and a long mouth, later simplified. He usually wears a three-buttoned uniform coat with a white collar, lighter pants, and running shoes, switching to a light short-sleeved shirt and dark shorts in summer. His height and build vary across media, ranging from relatively tall (150 cm) and slim (46 kg) to shorter and chubbier. Dental issues are a recurring trait, with official profiles noting at least three cavities, occasionally used as a visual differentiator.
Personality-wise, Osomatsu is fiery, self-confident, and pushy, frequently declaring himself the leader of his brothers. He is the strongest fighter among the sextuplets and often spearheads their mischief or schemes, from childhood pranks to outright bullying. Despite his troublemaking, he is described as well-liked due to his smooth attitude. He exhibits gluttony and greed, particularly for food and money, though he frequently has little to no savings. His leadership proves unreliable; he sometimes sabotages his brothers for personal gain, such as betraying them to win Totoko's affection or accepting adoption by a wealthy couple. These actions occasionally lead to guilt, prompting gestures like shaving his head in repentance or buying gifts for his mother. Conversely, he has shown delight at the idea of his brothers dying so he could be an only child, and they have similarly dismissed his concerns with callous remarks.
Osomatsu frequently antagonizes characters like Chibita and Iyami, though their dynamics vary between adversarial and collaborative. He has been blackmailed by Chibita over bedwetting, a recurring embarrassment ridiculed by his brothers. He hates green peppers and shares blood type A with his siblings.
The "Osomatsu-kun Grows Up" one-shot portrays an adult Osomatsu as a typical unmarried salaryman. In contrast, the "Osomatsu-san" continuity presents a divergent adulthood where his personality remains largely unchanged from his late teens. Here, he is a NEET with a "sixth-grader mentality," retaining his self-proclaimed leadership role while being laid-back and unmotivated. His design features an upturned nose, softer black hair with red tints, and outfits often reflecting his red color motif. He engages in gambling (horse racing, pachinko), sometimes stealing his brothers' savings to fund it, and reacts poorly to losses—destroying property or lashing out. He makes lewd remarks, stalks Totoko, and is criticized for having a "bland" personality compared to his brothers. Despite expressing hatred for being a sextuplet and fantasizing about being an only child, he feels a contradictory sense of responsibility toward his brothers, though his actions often worsen their situations. On rare occasions, he shows a softer, more supportive side.
The movie "Osomatsu-kun: Suika no Hoshi Kara Konnichiwa Zansu!" falls within the 1988 anime continuity, focusing on the child versions, with Osomatsu's core traits aligning with his child depiction.
