A DRAGONS LOST MEMORY

My name is Ryujin shi hanshu it's not my real name, I think sort of just gave it to myself alone as a cover. I lost my memories a while back to as how long ago I'm not sure. I don't know my age or true name all I really know about myself is that I'm something called a dragon slayer. To as the type of magic none are sure but I do know one thing I'm searching for some one. I don't know her name nor do I know the relationship between the both of us but I only know a subtle image of her. A woman with short pink hair that wears a maid outfit and has chains attached to her wrist. Ive been getting memories of the both of us being together on multiple occasions and the final memory ive gotten of her was a golden key I now hold in my palm. Now im on a journey to find her with any sort of clues I can get to return a memory that was once mine. Hopefully when I find her I'll be able to see her beautiful smile again and live peacefully. my story begins now.
