Sōjirō Kusaka

Sōjirō Kusaka (草冠 宗次郎, Kusaka Sōjirō?) was an old friend and rival of Tōshirō Hitsugaya when they were younger in the Soul Reaper academy in Bleach: The DiamondDust Rebellion. He is the main antagonist in the movie and a Soul Reaper which Hitsugaya encounters while searching for the thieves who stole the "King's Seal". He has the same zanpakutō, Hyōrinmaru, as Hitsugaya.
