Yukihime, an ice-wielding demon employed by the underworld, tracks fugitive demons under the guise of a detective agency operative. Her powers manifest as razor-edged ice blades, immobilizing frost, and shimmering defensive shields. Professionally detached, she masks simmering tension with her partner Enma, whose opposing elemental affinity fuels a concealed romantic pull. This vulnerability is weaponized when a manipulative demon possesses her, triggering collateral fatalities among comrades and innocents.

The core manga highlights her tactical ingenuity in combat: forging ice armaments to pierce fire-immune foes, cauterizing injuries through cryogenic healing, and reconstructing battle-damaged attire from glacial vapor. A sequel introduces betrayal by Kapaeru, a once-trusted ally, though her retaliatory measures remain ambiguous.

Existing records omit her origins or rank within the underworld, centering instead on her alliance with Enma, the psychological toll of their charged dynamic, and mission-driven collaborations. Spin-offs position her within ensemble operations against paranormal crises, prioritizing collective action over personal arcs.
