Ryo is unsure of what he really wants, but seems to care a lot about his partner nonetheless. He is uncomfortable with being constantly called by his Japanese name since this implies a certain degree of intimacy, and he is a very private man. However as Dee imposes this name upon him others begin to adopt it, and gradually he is forced to be more open. Highly suggestible, Ryo ponders frequently over the advice given to him by others and at times he questions his own view of himself, which tends to make him depressed.
Ryo loves children and tries to surround himself with warmth and affection. He is very compassionate, cares little for money but saves conscientiously and likes flowers. He has a strong idea of how he wants things to be, but Dee tends to spoil these plans, with his casual attitude to tidiness and his confusing behaviour. Whilst Ryo comes across to those who don't know him as friendly and shy, at times the control he has over his actions is broken by Bikky or Dee, exposing a more violent side. This appears to upset him on occasion, and may be part of the reason that Dee makes him uneasy.
