Kishirika Kishirisu, a member of the Immortal Demon Clan and former empress of the Demon Continent, appears as a pale-skinned child with voluminous violet hair and goat-like horns. Her heterochromatic eyes spin and shift color, housing multiple Demon Eyes. Her personality blends haughtiness and ambition with simplicity, gullibility, and carefreeness. She uses the noble pronoun "warawa," holds fierce grudges, and exhibits deep loyalty to her fiancé Badigadi, though their relationship remains platonic due to her child-like form. She readily rewards helpers, especially with food during starvation. Daughter of the First Demon God Kirisis Calisis, Kishirika was rescued as an infant from the collapsing Demon World by Necross Lacross and Laplace. Raised in the Human World, she later commanded demon forces in the Human-Demon Great Wars. Defeated 6000-7000 years ago, she endured three centuries of imprisonment. Post-reincarnation, her imperial claims were dismissed, forcing her into beggary amid perpetual hunger. Her interactions involve granting Demon Eyes for aid: she gave Rudeus Greyrat the Foresight Eye for food in Wind Port and the Clairvoyant Eye for a donut. She revealed Rudeus' family location and Zenith's imprisonment to Roxy Migurdia for covering a drinking debt, and provided Cliff an Identification Eye for food. Imprisoned by Atoferatofe Rybak, she disclosed Geese's whereabouts to Rudeus, exposed her and Badigadi's past as Hitogami's apostles, explained the Fighting God armor, and mentioned Badigadi's lingering debt to Hitogami. She pledged future assistance to Rudeus, excluding matters involving the despised Hitogami. Kishirika wields twelve Demon Eyes—Foresight, Clairvoyant, Identification, Magic Power, X-ray, Absorption, All-Seeing, Absolute Void, and Affection among them—requiring precise mana control. Despite her status, she panics under threat and lacks combat prowess. Her immortality stems from cyclical reincarnation upon death, resetting her age to explain her child-like form. Badigadi attributes her frequent deaths to thoughtlessness. Conventional magic circles cannot summon her due to immense mana capacity, and she cannot leave the Demon Continent. Physiologically, her metabolism is extremely low: fourteen skewers sustain her for a year. She perceives vast mana reserves as "disgusting," once mistaking Rudeus for someone fused with a stillborn twin. Her appearances involve unexpected entrances, becoming a running gag where Rudeus imagines scenarios like her being born as his child or summoned magically.
