Devil Union

Devil Union is a special transformation available to devil hosts who have undergone the Devil-Binding Ritual.

The host draws on the full power of their devil and assimilates the devil into their body, enabling them to contain and control the power of the devil and dramatically increasing their own magic power and capabilities. The host takes on physical traits of their devil, such as horns, a tail, and slit pupils, as well as being garbed in their devil's power.
