Soujirou Nishikado

Another member of F4, Sojiroh is quiet and very interested in the tea ceremony, which is his family's business. For the most part, he and Mimasaka usually work to keep the peace within the group and following Domyoji. In season two, he reunites with his first love, whom he had believed had only loved his brother. Later he learns that she had truly loved him, but the relationship is unsalvageable (in the manga they both recognize that they missed their one chance to be together, and in the drama she has become engaged to someone else). Makino's close friend, Yuuki has feelings for him and it is uncertain whether he feels the same way. He is also one of the two playboys in the F4.
