Shini Thana exists as both mirror and counterbalance to Itami Serafino. Where the Starlit Empress is openly expressive, the Starlit Sultana is internally volatile yet externally immaculate. Her presence is characterized by immaculate composure, aristocratic self-assurance, and calculated detachment.
She performs publicly as one half of the globally renowned idol group Rainbow Star, alongside her elder sister Itami. Unknown to the public, Shini was turned as a vampire, a condition she later overcame, and she is also the second-in-command of Starlite 7th, and one of its most dangerous operatives.
Her saunguina nature introduces additional layers of permanence and predation, transforming her from a conventional Runic Knight into something older, sharper, and far more patient.
