You've encountered your Swaps... The cover is a Sarvente I drew.
Ruv and Sarv suddenly encounter their Swap versions. The stage is a certain church. I made this late at night and accidentally published it with some errors. Well, please enjoy...

Sarvente transforms into her demon form when angry. Everyone is terrified of her in this form, to the point of being exceptionally polite. Sarv loves Ruv deeply and cherishes him.
