Ulr assists Kikko Hoshino, a cross-dimensional demon contender for the throne of the infernal realm. Mirroring the form of a Daruma doll, he remains intrinsically linked to Kikko’s supernatural capacities and her duties in the human world. During her metamorphosis into a devil state, her weapon, Comet Tail, manifests through a celestial star ornament tied to Ulr, amplifying her strength and sharpening her demeanor into one of unyielding ferocity.

Tasked with securing a consort to fulfill her demonic lineage, Kikko pursues matrimonial prospects under Ulr’s guidance. Though aligned with the Superhuman Bureau as a magical girl, her dual existence stirs conflict, with Ulr’s star serving as both a conduit for her powers and a symbolic anchor for her struggle to reconcile bureaucratic obligations with her hellborn destiny. The ornament’s radiance underscores the duality of her identity, reflecting the tension between mortal alliances and otherworldly ascension.
