The Dragon God's Bride

"I will not fogive anyone who lays a hand on my bride."

The Tenryu family has had women with powers of healing for generations, but when someone without those powers is born, they are treated as an outcast and treated harshly. Mitsuki was born into a power part of the Tenryu family but was quickly made an outcast as her lack of healing powers became apparent. At the age of seven, her mother suddenly passed away forcing her to move in with her aunt. Day by day, she has been treated terribly by her relatives due to her status as an outcast. However, all of that changed when the new head of the family came of age.
