Sōjirō Kusaka

Character outline
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 is 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.

Zanpakutō
Hyōrinmaru (Ice Ring): When sealed, Hyōrinmaru looks almost exactly like a normal zanpakutō with the exception of the guard, which is in the shape of a four-pointed star. The hilt and the sheath are also light-blue, which matches Hyōrinmaru's abilities.


 * Shikai: Its release command is "Sit Upon the Frosted Heavens". Hyōrinmaru is the strongest of all water-ice element zanpakutō in Soul Society. In its shikai, Hyōrinmaru itself remains the same, but gains a crescent-shaped blade attached to the hilt by a chain.


 * Shikai Special Ability: Hyōrinmaru allows Kusaka to control water and ice. His slashes create an immense amount of spirit power which overflows from the tip of the blade, creating a flow of ice shaped like a Chinese dragon. The dragon flies at opponents and instantly freezes anything it touches. The chain-blade also freezes anything Kusaka traps with it. The power it expels is so overwhelming that in Soul Society, its mere release actually effects the weather within the immediate vicinity.
