黒羽 紗雪

fortissimo//Akkord:nächsten Phase Description

Reiji's younger adopted sister, who comes off as a kuudere. She likes cats, and usually plays with them on her free time. She is very athletic as she is good at every sport in school. Supposingly, she is the same age as Reiji. She doesn’t talk much; but when she does, her messages are direct and to the point.
She has a very large rivalry against Momiji, as the two of them never agree with each other. But when they do, it comes off as a one time situation. The two of them constantly get into fights or arguments the moment they meet each other eye to eye.

After having awakened as a mahoutsukai, Sayuki uses her powers to help various people living in the island in the shadows. She is known as the "Guardian Goddess of Tsukiyomi-jima Island". By helping a lot of people, she has kept them away from troubles involving supernatural powers. Sayuki takes pride in her battle experience when dealing with magic or other mahoutsukais. She is considered a combat expert with her abilities. Using her abilities wisely, Sayuki is able to implement magic into her own body and use it to increase her speed at a godlike level. As long as the target is a living object, a monochrome devil's bullet shot by Sayuki's weapon is said to be unavoidable by any other skill.

Kadenz fermata//Akkord:fortissimo Description

Reiji's younger non-blood-related sister, who was reunited with him after four years. Sayuki tends to dote on her older brother to the point were she may have crossed the line as a younger sister. She leads a cat-and-dog life with Momiji, who goes after Reiji at every chance she gets. Although Sayuki does not talk much, her words are usually direct and to the point.

In the past, she used her magic powers to solve and deal with crimes in the shadows in order to protect Tsukiyomi-jima Island, allowing her to gain some battle experience. Sayuki's ability allows her to warp between space and time and move in it. She is able to move at the speed of light skillfully in combat. Because she awoke as a "Mahoutsukai" from an unusual circumstance, her magic weapon that should have been one weapon, split into two identical weapons.
