Phantoms and Wolves. Two completely different organisations but aim for the same goal. To hunt demons.
But what if a Phantom became the most powerful Demon of all?
The most powerful and the last of its kind.
What if everyone was hunting the Phantom down for that reason.
What it when you go to a place full of demons, you get a mate mark with the leading demon?

This is a story about all of that. Tasha is a Phantom and in the kingdom of Galantia demons roam to either live in peace or havoc. Demons can be good or evil. Tasha befriends a firefox demon and becomes a demon herself. What will she do?
