Nephrites

Elf princess of Romka. Her parents held the Ring of Wind and created a wall of wind with it to protect the elf city. She is a shut-in who was conditioned by her brother to be fearful of the outside world. As such she is very shy and has problems interacting with others.

She finally decides to help the Ring King and breaks the petrified forms of her parents, freeing the Ring of Wind. She agrees to go with Satou to fight the Abyss and becoming his 2nd wife.

At first she is fine with just being Satou's wife no matter where in line she is to receive his love, but her feelings for him are growing stronger.

She is self-conscious of her age compared to the others because she is an elf and much longer lived.
