Shūhei's zanpakutō is Kazeshini (風死?, literally "Death Wind"). When released with the command "reap" (刈れ, kare?), it takes the form of a kusarigama-like weapon, with two blades curving both directions, connected by a long chain. Although he dislikes the shape of his weapon because it is "shaped like something meant to reap life itself," he is extremely proficient at wielding it, capable of using the blades as both hand-to-hand weapons and projectiles, using the chain to make the weapons' paths unpredictable.
