A guy think he knows who he likes, but it's complicated. Both have a similar "realistic" feel to them. Very little, if any, filler. Both very engrossing.

Sakigake!! Cromartie Koukou
|
...then you might like
Angel Densetsu
|
Both are really great comedies involving delinquents. Densetsu derives a lot of humor from misunderstandings, while Cromartie gets it from visual silliness and weird trains of thought.

Goblin Slayer
|
Both MCs are out for vengeance. Goblin Slayer is far more sexual, and the vengeance is actually enacted, so the reader does get catharsis. Fire Punch is more about the pure hatred and willpower of the MC.
