The rule
Enten: Kuro, Aka, Nishiki, then shred and support extensions. Cloud Gouger: Mei, Yui, Kou, then cloaked Mei and Mei Shred. Tobimune: Owl, Crow, Suzaku. Kumeyuri: Play, Banquet, and the respect argument. The catalog teaches three as a household size.
Magatsumi: Dragonfly, Centipede, Butterfly, Bee, Spider, Malediction. Cobweb, rings, cuts through buildings, flowers, about 200,000 civilians. Dark power is ordinary diet. The three-count is how you know the other swords were trying to be tools. This one is a climate.
Why the count matters
Fandom kits that invent a third name for a blade that has not printed one fail the catalog. Two wartime swords stay unnamed, kit blank. This desk will not fill them. See the count file and the catalog.
Official chapters live on VIZ or MANGA Plus. This desk does not host pages.
