Ran Midō serves as a shrine maiden alongside her elder sister Sumire, jointly enforcing moral codes through supernatural methods. The siblings identify and punish perceived indecency by summoning a massive ritual-born octopus, as seen when they targeted a woman in revealing attire comforting a lost child—an act they condemned as improper. Their abrupt, narratively disconnected enforcement lacks explained motivations, personal backgrounds, or organizational context beyond this incident. Existing sources do not expand upon their origins, development, or roles in other narratives.
