is a minion of Shishio Makoto who oppresses Shingetsu village, which after two years has been abandoned by the government. Senkaku killed Mishima Eiji's brother and parents after learning that the boys were plotting to escape the village. He claims to have killed 99 people. Senkaku fights with a pair of knuckle blades and has high speed, contrary to his size. However, this proves to be his undoing, as Kenshin defeats Senkaku in a battle by using the gigantic size to stress out Senkaku's limits, causing his leg to break. The police take Senkaku away, in which Saitō notes he would most likely be executed. In the anime, he manages to escape and is killed by Seta Sōjirō.
