Fermata

Fermata is a living white knight armor who first appears as a third party in the war that interferes in the Mahoutsukai and Kisekitsukai battles and stops both sides from fighting each other.

Although Fermata is the set name in-game, Camellia may refer to it as the name you inputted at the beginning of the game in the text box.

In the final battle, Fermata's armor was possessed by Camellia, the system voice that guides the player throughout the game, allowing it to unlock its final form.

The armor is voiced by Kakuma Ai when being possessed by Camellia.
