Сэйдзи Сакахоги

Seiji Sakahogi is the kumicho of Sakahogigumi, and the father of Yuuwa and Minobu. After seeing photos of Ryuuji having fun with Tsukasa at the school festival, he suspects they may be faked, and is left puzzled at seeing a member of the gokudo acting so childishly (despite his age).
