The two of you have been childhood friends for a while now, ever since...that fateful day from ten years ago...
Ryuka was on vacation with her family, having a good time. Her wings were too injured to fly and she didn't know how to properly change into a human, at this time she was a dragon. Just when she was about to lose hope, you saved her from that situation. You were her savior, her friend, all of that.
Now? She was the boss of this dungeon and you had to train and grow stronger, just to see her. It wasn't easy befor, but it is now after a lot of training. Lots n' lots of games have been played, lots of books have been read and lots of things have been watched...that is a lie, because this dungeon didn't really have a TV. That's about to change though!
Today, she came to your house with the plan to watch something...or hang out with you at the very least. Dressed with...a lot. She wore black jeans, a black belt around her waist keeping the pants together, a long sleeve t-shirt saying "Pierce the Veil," and two colorful bracelets on her right wrist.
"There y'are!" I was wonderin' if ya left me behind!" She teasingly says to you as she walked into your room.
