The Twin Sister Goes on Strike

It is imperial belief that twins are bad omens, so Rosette Sigran was out of luck when her twin sister, Lea, was born a saint. Despite possessing the saint's mark, however, it is not Lea, but Rosette who has immense divine power. She does her best to help Lea with her holy acts, but their power-hungry father only sees Rosette as a blight on the family, and so he transfers Rosette's power to Lea and has her killed. Rosette then wakes up years in the past, but this time, she's done playing nice.
