Ryuu ga Yonda Musume

The village was called the "Village of Sinners" and was inhabited by the remnants of the previous king who lost the power struggle in the royal palace. There is only one way to cross the steep cliff and leave the village - to be called by a dragon. Mia, a 10-year-old girl who lives quietly in a village at the bottom of a valley, is called by a dragon and, although she is afraid of the outside world, she decides to leave the village. She is carried by the dragon to the lapis lazuli-colored royal palace.

At the palace, she meets mysterious witches and a dragon knight who has a strong bond with the dragon. Mia, known as the "Child of the Valley," ends up working as a roommate for the legendary dragon knight who was cursed and disappeared. As she struggles to survive in the royal palace, she becomes embroiled in a strange fate.
