Rio

It took some guts not to fight back given what he went through. I don't think anyone would blame him for taking the Hajime route and becoming an icy, stern loner.

Very well written, and what I enjoy the most is that he isn't the type of main character starting an nomadic harem, I mean, whenever someone (mostly/everytime a girl) wants to join his journey, he declines. He's always going from place to place alone, and that's something you don't see in every anime. It's a change.

Rio is very well written character, and he is also pretty op.

I like him because he's so cool
