Mituna is a pretty decent character for what they were trying to go for. I think he's pretty funny but also very easy to sympathize with, he went through a lot and deserves more respect than the others give him. He is quite literally just a guy whose doing his best to learn how to perfect his hobby, maybe he's a jerk and sexist sometimes but those are just quirks! (Joke + reference XD)

Also sidenote, he's weirdly fun to roleplay as. If you've never roleplayed as him before, definitely give it a shot.
