Ai Astin from Kamisama no Inai Nichiyoubi. I just love how cute and innocent she is. How she try to be mature yet is still a child.
Uhhhh . . . did you read my post? This is about characters. Hiruma is the captain in Eyeshield 21, I chose L for Death Note, and have you read GTO?
I like Saitama. The part about him still having difficulties as a human being makes him relatable. And Ushio. He had went through some horrible experience that might be enough to turn someone to the dark side, or at least become antihero. Yet he still had his positive attitude. In fact, his positive attitude inspired a lot of people, be it human and youkai to band together to fight the final boss
