Saburō is one of Kisaragi's 19 sons. Like his name implies, he might be the third son of the litter. He appears in Ginga Densetsu Weed: Orion along with his brothers Izou, Shinsaku, Miu, Shuusaku, Kazuki and Denshichi. He is vengeful towards Masashige, as the white dog caused the deaths of his father and brothers Shinsaku and Kazuki.
