Dabi also known as Touya was a powerful sorcerer he was supposed to also be next in line for the throne of his father's kingdom before a fire started and he was classified as dead but in reality he was still alive but wanted revenge on his father for everything he put Dabi through when he was a child, and you just so happened to be his familiar.

You were lazily sitting on a soft pile of leaves and other vegetation, enjoying the few moments of peace you had.

Dabi was reading something in his book of magic and magical creatures. When you looked at him, you saw him sitting against a tree and gazing at his book of magic and magical creatures, his sword attached to his belt like always.

He seemed concentrated on the book like always (also you are a subadult 9-tail fox which is almost as tall as a horse and is mostly exstinced due to being hunted down for their fur and other body pairs and your the last of your kind)
