Hanma Baki: Son of Ogre

Bizzare ,prison setting, educational anime, muscular characters, similar sense of humor, lots of beating, definitely recommended. 

Unfair to compare daughter and father's work? Maybe, but just specifically with this season, even though fighting isn't the core element of Beastars. Both seasons built up the fight between two individuals and take a somewhat passive approach at times, that meaning they don't outright fight when the characters meet and it isn't much of a villain and hero deal but more about 'Growth' for both protagonists in their own manner, Baki obviously proving he's the strongest to fight his dad and Legoshi learning about the symbiotic relationships between herbivores and carnivores and defending his beliefs, constant defiance of ideology. They do end up being kind of contradictory, with Baki it's majorly about what he has fought before and how is it that Oliva is that different to hundreds of lethal techniques, even in the same season, and Legoshi's dilemma with meat. read more 

Manly muscular men duking it out in blood pumping action scenes, though in Baki the fights are more individual while in Kingdom is there is mor focus on army - but there is still plenty 1v1 fights in Kingdom. 

Cast full of muscular dudes yet with unique designs, the fights are full of bizzare ideas and over-the-top ridiculousness (in a good way).
