Suseri Shimazu  

, 島津 須世璃

The girl in question is a relative of Sakuyas and possesses the same abilities as her. However, unlike Sakuya who is self-centered and impulsive, this girl is composed, thoughtful, and refined. Although she could have been Asanos fiancee, which would have guaranteed her position as head of the Shimazu Household of spirit mediums, she chose to relinquish that role to Sakuya despite their animosity. Despite everything, she still harbors feelings for him. In combat, she harnesses her powers through her familiars known as Kamai Tachi.
