Renji Abarai is a character in Bleach created by Tite Kubo. In the series, he initially dedicates his life to defeating Ichigo Kurosaki, the protagonist of the series, before joining forces with him to rescue Rukia Kuchiki halfway through the Soul Society arc. He has since become a major protagonist and a consistent ally of Ichigo. His weapon is Zabimaru.
Its Shikai command is "Howl". In its Shikai, Zabimaru transforms into an even longer 6-part segmented blade; each segment is wider than the one preceding it from the hilt, with 2 pick-like protrusions on the front and back of each segment, with the ones on the front much longer than the ones on the back. The segments of Zabimaru can grow in number almost without limit.
The cowl portion of the Bankai transforms into a large, skeletal arm that follows the movements of Renji's own left arm. HihiĊ possesses considerable power, having enough strength to crush bones and effortlessly throw around large opponents with relative ease. It is strong enough to effortlessly lift up a large slab of wall and crush it into pieces with minimal force.
