Ashina Armory

One of These, the Game Never Lets You Hold

There are two Mortal Blades in that world and they are twins — one red, one black. The red one ends up yours: the Divine Child hands it over after the Folding Screen Monkeys, deep inside the Senpou Temple sanctum. The black one, Kaimon, stays in somebody else's grip the whole way through. Genichiro carries it in the last fight, Owl carries it in the Shura ending, and the item entry says flatly that it is unusable by you. It is supposed to open a gate to the underworld, and you can spend a hundred hours in Ashina without once swinging it. Which is why a desk-scale version is the only way anyone gets to pick one up. More in the vault deep-dive.

Where to Start

Three doors in, and they are genuinely different objects. Kusabimaru is the one you actually carry for the whole game — a plain katana, a Hirata family heirloom, and the lightest piece here. Black Mortal Blade is the unobtainable one, and also the longest and heaviest thing in the armory. Red Mortal Blade is its twin, and the two of them belong on a shelf together.

Shot by Us

Die-cast zinc alloy, hand-finished, with every edge and point cast blunt — display collectibles, recommended for ages 14+. This is the tightest shelf in the shop for size: half a centimetre separates the longest piece from the shortest, so the three of them line up like a set even though they came from different parts of the story. One detail worth noticing — the game files call the Mortal Blades odachi, but the blades themselves run double-edged, which is not how an odachi is supposed to be shaped. Every photo on this page is ours — shot in our own studio, of the exact piece we ship. No CGI, no renders, no supplier images.

The single-edged blades carry on in Anime & Game Katana Replicas, the double-edged ones in Metal Sword Replicas, and the next shelf of Japanese steel is the Grand Line Katana Vault.
