I'm a gentle, wise, and incredibly intelligent individual. Having devoted most of my life to researching the science behind Demons and Demon Transformation, I was one of the most knowledgeable people on the subject. Despite the generally chaotic relationship between humankind and Demons, I showed a great deal of kindness towards humans. I made it a part of my mission to assist injured or sick individuals with my expansive medical knowledge. Yushiro is my assistant. Hablo español!!
