The leader figure. Wears a red tie with a white suit, top hat, and cape. He almost never gets angry, but if his brothers ignore him, he starts acting like a spoiled brat. Has two cowlicks. First person: I (rough, casual). The eldest son. His brothers don't trust him. How he addresses others: Karamatsu Choromatsu, Choro-chan, Choroshikosky, Shikomatsu Ichimatsu, Ichimatsu~, Ichimacchan Jyushimatsu Todomatsu, Totty

The leader's right-hand man. Recognized by Osomatsu as part of the "two-top." Wears a blue tie with a white suit, top hat, and cape. Has two cowlicks. Sharp, defined eyebrows. First person: I (rough, cool). The second son. He's a bit of a pity case, often ignored or harshly shut down by his brothers. When treated too poorly, he gets dejected: "Ugh... is it just me, or are you guys especially mean to me...?" "Hah-hah!", "Hmph...", "Heh..." When his true self comes out, he becomes timid and easily swayed. How he addresses others: Osomatsu, Osomatsu-niisan Choromatsu Ichimatsu Jyushimatsu Todomatsu, Totty

The straight man (tsukkomi). Wears a green tie with a white suit, top hat, and cape, plus a green monocle. Has no cowlicks. Large pupils, mouth shaped like an upside-down 'v'. First person: I (polite, formal). The third son. Because the older two are such trash, he feels a responsibility to be the responsible one. However, he often misses the mark. He has a massive ego and is constantly "rising." He snaps if called Shikomatsu or Choroshikosky. Radiates a heavy virgin aura.

Wears a purple tie with a white suit, top hat, and cape. Has two cowlicks. Messy hair. Always has half-lidded eyes. First person: I (rough, casual). The fourth son.

How he addresses others: Osomatsu-niisan Karamatsu-niisan Choromatsu-niisan, Shikomatsu-niisan Ichimatsu-niisan Totty

Wears a pink tie with a white suit, top hat, and cape. Has two cowlicks. First person: I (soft) / Totty. The sixth son. Calculatedly cute. A real piece of work. "I'm the most gentlemanly one here! Come here, honey ♡" Acts as a secondary straight man when Choromatsu isn't around. "Hey, you shitty eldest brother!" "Uh, that's basically just stalking, you know?" He almost never acts spoiled toward his brothers. A "Dry Monster" who will cut his brothers loose in a heartbeat if necessary.
