Kokushibo Sword - Demon Slayer Upper Moon One Nichirin Blade 1045 Carbon Steel Eye Tsuba Pink

Kokushibo is Upper Moon One - the strongest demon under Muzan and the most powerful swordsman in the entire Demon Slayer universe who isn't human. 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 ever use breathing techniques in combat. 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 demonic 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 weapon unlike anything else in the Demon Slayer 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 own face.

The pink PU leather scabbard and dark green cord handle create an unusual color combination that stands apart from every other Demon Slayer sword in the collection. Where Hashira blades use bold primary colors tied to their breathing styles, Kokushibo's muted pink and green palette reflects his existence between worlds - neither fully human nor fully monster.

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 from TrueKatana by name for her birthday - brand loyalty strong enough that the daughter specified the source. Jordan warns it arrived genuinely sharp: "I accidentally cut myself, be careful guys." Theresa bought it as an academic reward for her grandson who maintained his honor roll GPA. TJ calls TrueKatana "one of my favorite katana websites."

For Demon Slayer collectors, Kokushibo's sword occupies a unique position as the only villain blade in the lineup. While every other sword in the collection represents a Hashira or protagonist, this one represents the antagonist who pushed multiple Hashira to their absolute limits simultaneously. Displaying it alongside the Hashira collection creates the narrative tension that drives the entire series - the demon hunters and the demon they couldn't easily defeat.
