Miho Sato

Toshiya's younger sister. Miho was taken with their parents when they abandoned him. Despite her parents disliking her mentioning Toshiya, Miho watched her brother. She appears in the fifth season, meeting Shimizu at the airport. Miho offers to allow Shimizu to stay at her hotel learning of her money problems. She later reveals to Toshiya that she is his sister; the trauma leads to him passing out. Miho almost returns to Japan, thinking that it was all her fault, but Toshiya does not blame her and asks her to come to the games (via telephone) saying that if he knows his sister is cheering him on, he can do better than ever.
