Story
Kishirika is known above all as a bestower of Demon Eyes. It is she who grants Rudeus his Demon Eye, and later, in Perugius's fortress, she bestows on Cliff Grimoire the Demon Eye of Identification, which at first he cannot control.
She is sought out even later: Rudeus leaves a request at the Adventurers' Guild for her whereabouts, with a description — “a little girl, purple hair, a bandage outfit, introduces herself as the Great Emperor of the World, maniacal laughter.”
Her word carries weight even in the finale: when Orsted defeats her brother, the Battle God Badigadi, it is Kishirika's plea “do not kill him” that decides his fate — Badigadi is sealed rather than executed.
