There was a manga about half-alien (he did not know he was an alien at the beginning of the story) and a hero who protected the world with his comrades while risking his life everyday. I remember that the alien was a blonde and a hero was a dark haired guy. Does anyone remember the title?
Naaah the squirrel has to go.
