Norio Koga

The other missing passenger from the plane flight, as well as Takeo's roommate and friend. Norio has long hair, earrings, large eyes, and other feminine features so many characters throughout the series mistake him for a woman. He possesses a high-level shadow dragon that often follows Takeo, and crafts new shadow dragons as a sort of hobby. Norio is very aloof and rude around other people, and it is touched on a few times that he is angry at the human race. But he actually has fierce loyalty for Takeo, and his deepest, darkest wish is to have a child.
