Nin-Nin (ニン忍): Nin-Nin is a midget ninja who is always hooded. He is Miko's loyal, yet sexually perverted, companion and sidekick. He likes to peep when Miko is bathing or masturbating and beams with joy whenever he can see her naked, or barely dressed, or in any troublesome sexual encounter with demons or other ninjas. On the other hand, he takes seriously to heart his role as Miko's protector and always try to help her out whenever she's in trouble, or at least whenever he is not busy taping her "exploits" for future reference.
