Product Details
Kokushibo is Upper Moon One - the strongest demon under Muzan and the most powerful swordsman in the Kimetsu No Yaiba universe. He was born Tsugikuni Michikatsu, twin brother of Yoriichi, the creator of Sun Breathing. Where Yoriichi mastered the breath of the sun, Michikatsu chose immortality and became the first demon to use breathing techniques in his art. His Moon Breathing created crescent blade attacks that multiplied with each swing. After centuries as a demon, his Nichirin blade grew eyes - a physical manifestation of his transformation fused into the steel itself.
The 1045 carbon steel blade recreates that signature design: a red base with yellow eyes running along the steel, capturing the unsettling organic quality that makes Kokushibo's sword unlike anything else in the series. This is not a clean, elegant Hashira blade. This is a sword that looks alive. Full-tang construction at 40.5 inches and 3.2 lbs. The alloy tsuba features a circular shape with four indentations, three eyes at the center surrounded by black veins and a golden border - mirroring the demonic eyes that cover Kokushibo's face.
The pink PU leather scabbard and dark green cord handle create an unusual color combination that stands apart from every other Kimetsu No Yaiba sword. Where Hashira blades use bold primary colors tied to their breathing styles, Kokushibo's muted pink and green palette reflects his existence between worlds.
Marco calls it "perfect and very well balanced." Abigail plans to come back for more "just based on how beautiful these katanas are." Shana's daughter specifically requested this sword by name for her birthday. Theresa bought it as an academic reward for her grandson who maintained his honor roll GPA.
For Kimetsu No Yaiba collectors, this occupies a unique position as the only villain blade in the lineup. Displaying it alongside the Hashira collection creates the narrative tension the series is built on. Browse the full Nichirin sword collection for all available builds.
