Metal Sword Shinji Hirako's "Sakanade" Katana

Like all Zanpakuto, Sakanade has a release command that allows Shinji to unleash its true power. The release command for Sakanade is "Collapse" (hakai), which causes the sword to disintegrate into several petals of light. When the petals dissipate, Shinji's appearance changes, and his abilities are greatly enhanced.
