Koran Enno serves as the spirited younger sister of Kocho Enoki within Heian University’s covert supernatural defense efforts. Operating under Professor Kamo’s astrology club, she joins her sister and Kosaku Urano—a human decoy tasked with attracting spirits—in conducting exorcisms.

Her bold, flirtatious personality starkly opposes Kocho’s timid restraint. Koran openly showers Kosaku with unabashed affection, disregarding her sister’s visible jealousy and amplifying comedic friction during missions. These antics often clash with Kocho’s disciplined demeanor, injecting unpredictability into their supernatural confrontations.

Though integral to the team’s exorcism operations, Koran’s methods lean toward playful provocation over strategic cohesion. Her relentless teasing of Kosaku sometimes derails mission focus, yet she persists as a steadfast combatant against paranormal threats. By channeling her assertiveness and magnetic presence, she bolsters the group’s dynamic, balancing chaos with unyielding resolve in their shared supernatural battles.
