the nurses that he and Honoka (the clone) have begun to develop a mutual affection. Numbers characters "Numbers" are clones created by H Ring Man and are so-called because of numbers tattooed behind their right shoulders. In an effort to distinguish themselves they created names for themselves. The H Ring Man is the head of the organization which created Ray and the "Numbers" children. He was responsible for the loss of Ray's eyes as well as the parasite which infected Red Ribbon. His real name is , and along with Ray's mother Dr. Kasugano and Dr. Sawa, he established the hospital where Ray and the others now work over 20 years later.
