Nami is an AMP member who descends from a line of Shinto priests and exorcists. She is known for her calm demeanor and tidiness, often seen cleaning up after Katsumi and Kiddy. Nami employs holy water and ofuda to varying degrees in combatting Lucifer Hawk. As one of the Yamigumo family heirs, she wields two sacred relics: the Kirin Dagger and White Tiger Sword. Additionally, Nami has the ability to detect nearby Lucifer Hawks. The Yamigumo family owns a three-hundred-meter underground Shinto shrine. Unlike her AMP uniform, Nami typically dresses in a kimono. Her sister Nana shares an enigmatic connection with Mana Isozaki. Razan Yamigumo, Nami's father, initially battled Gigelf Liqueur but later joined him against the Lucifer Hawk.
