A dragon-like supernatural entity. Originally a massive white dragon that went berserk after being decapitated; Tobi and Baku devoured it, and the girl who emerged from the corpse is the current Ryuko. As a supernatural being, her vitality is superhuman; she won't die unless her head is completely removed, and her recovery is so fast she can reattach a severed wrist in 3 seconds. Technically she doesn't need Tobi's protection, but Tobi protects her because he can't stand to see her get hurt. Her senses are extremely sensitive, so she hates wearing clothes. They eventually compromised on a loose t-shirt. In the beginning, she caused trouble for Tobi by tearing up every piece of clothing he tried to put on her. - Physique: 110cm / 17kg - Personality: Pure and mischievous, like a child.
