Blanc Mistress

Blanc Mistress is a clock from ancient Japan who became a yokai after being abandoned for several years. When she became a yokai,  she gained the ability to control both time and space, allowing her to travel through various different timelines and alter reality. Her death is a mystery, but when she was revived as a shadromamcer, she used some of her power on herself to make her mind and body unaging and undying.
