I am tired of only Ichimatsu being seen\portrayed as yandere. Don't get me wrong, sicko psycho Ichimatsu that goes nuts and starts a bloodshed is very dear to me. But the point is, that all of those entitled, selfish, shitty incels could be yanderes!!! And we need to recognize that!!!
Osomatsu? Classic, as soon as his significant other (who is, let's be honest 90% of the time would be his brothers) start to drift slightly away, changing the picture around him, changing anything he is used to, he will do anything to keep it from happening. Doesn't even have to be a romantic thing, he is so aro, he would go yandere on anyone he is even platonically attached to. Season four is full of cowards, if Chibita tried to get away from, like, Season one Osomatsu, he would get his knees broken. "Don't leave me" type of Yandere.
With Karamatsu it's not that much of a stretch to say that the guy that is always three seconds and two social blunders away from getting on his knees and starting to beg to be loved would go over the board once he gets his affections. You give him a nail he'll bite off the whole arm. And, obviously, when he gets love for himself or one of his personas, he will overplay this image to squeeze out every last second of love his significant other can give. "Love Only Me" type of Yandere.
Choromatsu seems docile, I know. But we also all know that he can get tangled up in his emotions and delusions. Do i even have to explain it? He presumably bought and buried a sex doll to play out his own yandere fantasy with a friend he never had. "I made up our bond and you have to commit" type of yandere. Bonus points, because with his constant need to be "proper" he will also gaslight the hell of his significant other.
I am skipping Ichimatsu, because, yeah, he would kill his significant other\for his significant other\ himself, he is the canon most yandere yandere we stan. But still typing him as a yandere would be "I love you and i show it with violence" type of yandere.
Jyushimatsu has his sweetness to him, however, he is known for getting overly excited and reactive. To the point, where it overtakes his gentler side as we saw with Eitarou, for example, when he yeeted him. He wouldn't react violently towards his significant other, but he would very easy fall into a try-hard category, hanging around, biding to every need and using all of his energy to worm himself into every last part of his significant other life, including, but not limited to violence against outsiders. "I will work hard to make you love me" type yandere
And Todomatsu, the Dry Monster. Honestly, he could be anything. I can see him separating his significant other from other people, stalking them, lying and coying his way into their heart, deluding them into the feeling that he fits them more than anyone else. He is guns ablazing, all in, firing on all cylinders, when it comes to getting something he wants. And once the significant other that will take care of him and pamper him and adore him appears, he will do everything to keep them as close as possible. "I need you with me, so you are staying with me" type yandere
