A young man apparently in his mid to late twenties, Tofu is a kindly neighbourhood chiropractor who has an unusual amount of knowledge about ancient martial arts lore and esoteric knowledge in general. He is the Tendo’s family doctor, and has apparently been serving in that capacity for quite a long time. He has, as far we are shown, had an intense crush on the Tendo’s eldest daughter Kasumi since they were both much younger, and the passing of time and Kasumi’s maturation have only intensified it. This infatuation is so intense that the mere mention of her name can cause him to lose track of his surroundings, and her actual presence throws his mind into babbling confusion, which can be very hazardous for people or objects around him.
Doctor Tofu is an accomplished martial artist. While his combat ability is not shown in the series, he is highly respected by Akane and is capable of sneaking up on even the likes of Ranma without being noticed. He has a formidible command of pressure point and chiropractic techniques, which can cause effects ranging from near-instantaneous healing of injury to delayed paralysis of limbs.
