The adult design of Osomatsu in this series depicts his nose as more upturned than it was in -kun, while his mouth is more long and hanging like his early design. His hair is a softer shade of black, so as to not overpower the blue lineart, and is depicted as having red-tinted highlights to set him apart from the other five.

As his image color was decided as "Red" for this series, it is often seen reflected in the outfits he wears with the exception of the formal blue suit jacket seen on some occasions. As he is envisioned as the "standard" sextuplet from which the others' designs are branched from, it is likely why he is usually seen wearing his Matsu parka as the default outfit during times when the others all have some unique types of fashion.

He tends to grin in a wide, toothy way, and in the first season can often be seen rubbing his finger beneath his nose as a general character tic.

Personality

The older Osomatsu in -san is described as a "Miraculous Idiot" in his profile, and like the rest is a virgin and NEET but one with "the mentality of an elementary school sixth-grader".

He retains some of his bull-headed ways from his youth, and still presents himself as the leader (and, subsequently, the "most responsible" of the group, much to Choromatsu's particular disagreement). However, he is now more laid-back and much more foolish than the take-charge and rough child he once was and has less motivation to get things done unless there is an instantly gratifying goal in mind. Even then, unless it's something all the sextuplets would want to work for, he'd think nothing of sabotaging a brother and humiliating them for his own amusement and gain, but can also be sabotaged by others on opposite occasions.

Though he expresses his hatred of being a sextuplet to Chibita and wishes that he was an only child, Osomatsu feels that he still has the responsibility to take care of them (which, ironically, is often the opposite of what he actually does in making things worse for them). Whether he still deserves his title as the "best fighter" is debatable, as he can be taken out quite easily by his own brothers' rage on different occasions, but he still thinks of himself as such in any case.

This adult version of Osomatsu is heavily into gambling, namely horse racing and pachinko, and will grab up his brothers' savings if he so wants so that he can pay for that habit. He is not a fan of losing, causing his addiction to sometimes escalate to more extreme measures; he has been known to destroy other people's belongings in an attempt to turn things in his favour, and even once attempted to strangle a fowl after losing a bet in a cockfight.

He has no shame or hesitation about making lewd remarks in front of his brothers and the women they may be around, usually ending in humiliation for the brother but sometimes some retaliation against him as well (as seen when Choromatsu threatens him in episode 2). His lecherous ways, at their worst, can even be to the point that he attempts to stalk Totoko and watch her changing from her bedroom window but receive punishment for such a thing.

Because his character type contrasts with the others' more exaggerated differential traits, Osomatsu's role may sometimes seem blurry and it can be wondered if he has any unique personality points. This is to the point where he's mocked for it and thought of as a bland, shitty face with nothing special in characteristics about him.

Occasionally, for as much trouble as he gives his brothers, he may be touched by an issue and show a softer, more relenting side to their situations and want to help in whatever way. But of course in other instances, he may only succeed in making more trouble.

When it comes down to situations where it seems like his status quo will be threatened by the others leaving or getting ahead, he will either show open resentment and feel abandoned if others succeed, or he'll remain supportive yet feel empty and like something isn't right with the situation. Needless to say, to his relief, these moments are as temporary as any other skit setting and he'll gladly welcome back what's fun to him.
