Rose

Shadow Joker's twin sister. Rose is a bubbly and cheerful girl, wide-eyed and optimistic. Though she is very kind and trusting, how trusting and uncaring of danger she can be makes her brother anxious. She trusts her brother, but has a far more relaxed, perhaps slightly naïve attitude towards her own safety.

Beyond her kind and seemingly gentle exterior, Rose can be incredibly intimidating when angered. Despite this, she is usually composed and level-headed—far more so than Shadow—and she loves her big brother dearly.

Rose and her twin brother, then known as Cyan, used to live in a unnamed village and she was the witch of that village. Unlike her older twin brother, Rose was born with magical powers. Rose mainly uses her powers to move and carry objects around, but also has the power of time manipulation, the ability to control time and freeze it in place.

One day, while heading out of the village, she and her twin brother met Joker, then known as Jack. After a series of events that led them to get to know each other better, they returned to the village, only for them discover it had been raided by mysterious people. When the raiders attacked Jack and Cyan, she was enraged and used up a majority of her power to attack them, which sent her into a coma.

After being freed from Professor Clover's control by Shadow and Joker's friends, Rose becomes an ally to Joker and lives with Shadow. She decides together with Shadow that they should take a trip around the world, since it was the latter's dream as a child.
