Ono Tofu

Japanese name:	小乃東風
Nickname:	Doctor

Dr. Tofu is the resident chiropractor and well-liked by the residents of Nerima. He is also a martial artist, though never seen practicing, and is quite competent at tending Ranma and Akane in their various scrapes. He is also madly in love with Kasumi and becomes quite dangerous when she is around. In these instances, he becomes an incompetent fool, sometimes harming his patients. Sadly, Kasumi does not seem to understand his feelings. He always seems to know what to do — until Kasumi arrives. The anime gives him a larger role, though in both mediums, he becomes a minor character who is almost nonexistent after the first few stories. Akane was in love with him first, and he was the reason she had long hair. It seems Akane gave up on him, after her hair was cut short in a freak accident.
