Mitsunari Yanagisawa (柳沢 光成, Yanagisawa Mitsunari) is a human who develops superhuman powers as a result of the demon plane hole opened by Sensui. His power is "Copy" which allows him to copy the appearance, memories, attributes, abilities, and spirit print of anyone he touches. In his last appearance in the manga, he is too shy to ask an attractive girl out, and it is revealed that ten years later, he marries the girl that tries to cheer him up. In the anime television series, Yanagisawa is voiced by Mitsuaki Madono in Japanese and Travis Willingham in English.
