Hyorinmaru is a fictional sword from the anime and manga series Bleach, created by Tite Kubo. It is the zanpakuto of Toshiro Hitsugaya, a captain in the Gotei 13. Hyorinmaru has ice-based powers, allowing Hitsugaya to manipulate water and create ice constructs during battles. The sword's shikai, or initial release, enables Hitsugaya to freeze his surroundings and create ice dragons. Its bankai, known as Daiguren Hyorinmaru, enhances its abilities, allowing for larger ice formations and powerful attacks. Hyorinmaru symbolizes Hitsugaya's strength and determination as a warrior.
