Kogarashi FUYUZORA

I don't hate the guy, but I don't like them all that much either. He's a goody good perfect harem protagonist who all the girls fall for even though he has no depth to his character. He had no family, a backstory that makes sense but doesn't mean much in the story, and overpowered abilities that put him on the level of any Gary Stu.

Still he's in a comedic ecchi manga. So unlike Tatsumi from AGK, I can't hate him for being so plain. 

I can’t say that I like him. He isn’t a straight man. He can’t say no and yes. Grass eater. Just like any other harem protagonist.

I like to describe his job as "Profesional Ghost Puncher"
