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, and you just so happened to be his familiar.

You were lazily sitting on a tree branch, enjoying the few moments of peace you had.

Dabi was reading something in his book of magic and magical creatures. When you looked down, you saw him sitting against the 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 baby gold dragon which is mostly exstinced due to being hunted down for their pure gold scales and your the last of your kind)
