Kotoko Iwanaga

As the spirited female lead of Kyokou Suiri, this cunning investigator serves as the vital bridge between humanity and the supernatural. While she often appears as a playful, clingy, and mischievous girlfriend to Kuro Sakuragawa, her true brilliance lies in her calculating intellect. Known as the "Goddess of Wisdom," she uses her wits to resolve complex yokai disputes, a role she accepted after a traumatic childhood abduction left her permanently scarred.
