Move Feather

Synthesis > Move Feather

The molted feathers of a black bird that soars among powerful monsters.

Description
Muvs are black birds known to migrate in flocks among other powerful monsters and demons. Seen as scavengers that bring bad omens, their feathers are detested and have little value among common people who do not even consider it as a useful material. However, when used in a concoction only known to the Demon Slayers, it is said to be able to refine highly powerful magical catalysts.
