Unite Mode: Gallus × Felis

Unite Mode: Gallus × Felis (モード: ガルス × フェリス) is a Shadow Magic spell.

Description
With an open grimoire, the user assimilates Walgner and Plumede into their body through Shadow Magic. The spell enables the user to contain and control the power of two devils, dramatically increasing their own magic power up to the level of a highest-ranking devil.

During the transformation, the user is covered in clothing made of shadow. They have the feathered shoulders and wings and taloned hands of Unite Mode: Gallus and the legs and hood of Unite Mode: Felis. Covering their face is a bird-like mask with a mandible under the user's chin. Both devils' horns protrude from the user's head, and the long tail is tipped by both feathers and a fork.
