Shigure

Shigure is an ordinary katana fitted with a blue handle and a blue, four-petaled guard, both rendered green in the anime. The blade itself is unremarkable, but the scabbard stands out: its upper section carries a bumpy green texture while the lower half runs white and smooth, with circular motifs embedded across the whole length. Following the timeskip the petal shapes on the guard took on a rounder look.

Little of the sword's potential has been demonstrated, yet what has appeared speaks to genuine quality. It endured clashes with Zoro's Wado Ichimonji, a notable feat given that Wado sits two grades above it, and it withstood the impact of a cannonball, deflecting the shot through Tashigi's handling. The blade also traded blows with Monet's wing blades, weapons that had previously matched Zoro's Sandai Kitetsu and Shusui.

Tashigi's signature move with it is Kiri Shigure, a quick-draw strike in which she sweeps past a foe and cuts in a single motion, ending with both hands raising the blade overhead parallel to her back. She first used the named version against Monet, though an identical unnamed cut had felled Koze and Packy back in Loguetown. Various games add further techniques such as Kamaitachi, Ranga Cho, the Usugasumi mist series, and Ki Hayate.

Shigure belongs to Tashigi of the Marines. The blade's name carries poetic weight: while it literally reads as timely rain, Japanese verse treats it as a marker of late-autumn showers, and it can stand as a metaphor for weeping, perhaps echoing Tashigi's belief that Famous Blades cry in unworthy hands. English releases have rendered the name several ways, including Autumn Rain, Showers, and Retrieval, while Funimation kept it untranslated.
