Shizuka Midoh serves on the Miko Council, an organization dedicated to opposing supernatural threats. Born into immense wealth, her family's fortune shapes her lifestyle and social position. She maintains a quiet, demure presence, consciously striving to embody traditional Japanese femininity in her behavior and demeanor. Shizuka holds profound admiration for Yuzu Hieda, whom she regards as a heroic figure worthy of emulation and deep respect.

Within the Miko Council, Shizuka wields a ceremonial fan as her talisman, channeling her spiritual abilities through it during combat. This fan empowers her signature "tornado blast" attack against hostile forces. Her choice of weapon and combat style reflect her overall emphasis on grace and refinement.

Her documented background centers on school life and shrine activities, with no further personal history detailed. Shizuka's narrative role focuses on her participation in group missions, interactions with fellow council members, and her consistent portrayal as a reserved individual devoted to her shrine maiden duties. Her affluent status occasionally surfaces in overt displays, such as residing in an exceptionally large and ornate house.
