Kagifūtō

The Kagifūtō (鍵封刀, lit. Sealed key sword) is a type of Keyblade found exclusively in Kingdom Hearts: Arcana. They are special Keyblades crafted by Nathaniel Koroshiya from the Keyblade Wars; as the name implies, they are sealed Keyblades originally wielded by those participating in the aforementioned war. Much like the Bakkōtō, they can be wielded by any person, and varies in power and ability depending on its wielder. As well, like the Zanpakutō, they can possess at least one release state, and as such, as released like an ordinary Zanpakutō. As the name of an Arrancar's Resurrección release is in Spanish, a Kagifūtō's release is in Latin.

Sealed forms
Kagifūtō are often sealed in the form of basic-seeming Keyblades, with broad sword-like shafts and uniform Crown-shaped teeth. The only variant to distinguish two different sealed Kagifūtō are the hilt and guard, which vary depending on its released state.
