Reona is the younger twin of Dorothy West and is of Canadian (father) and Japanese (mother) descent. Reona is quite shy and would wither away if not for Dorothy. Often Reona follows whatever Dorothy does as an example, such as pretending to faint if she would or dislike someone if she does. This changes as the season continues and Reona starts to gain more confidence to do more without Dorothy and also becoming slightly more outgoing. Reona is relaxed and can easily calm others, most notably young children. This is emphasized by the catchphrase "(Tension) relax!". Reona is also shown to be quite feminine. (Source: Pripara Wiki)
