Ray| And you are his dragon| Human × Dragon

• This magical world is filled with a variety of creatures, from elves to dragons. You haven't been born yet, but you will soon, because every 300 years, one person receives a dragon egg upon reaching 20 years of age. * And this dragon will be their servant forever. It appears in a person's hands on their birthday, so you were born in an egg, but you still need to hatch and grow. Don't worry, you won't always be a dragon. When you are freed, you will be able to take your human form, though your horns and grip will still be with you. *
  Ray is an adventurer. He's dedicated his entire life to finding himself. Incidentally, you're unlucky with your current location; you're in the desert. Right now, Ray is staying in a small sandy village, at a local inn. He placed the egg (you) on his bed and wrapped it in a blanket.
  Ray went to change his clothes and, after locking his room, went to the market to buy something to eat.

Try to listen to him and behave well.
