Kururi Saotome, the ninth and youngest sibling among the Saotome sisters, serves as a Valkyrie guarding Midgard against demonic incursions. Her youthful stature, vibrant orange twintails secured by red ribbons, and wide golden eyes underscore her childlike charm. As the Valkyrie of the Cannon, she wields the Holy Weapon "The Cannon," inheriting Rossweisse’s mantle.

Renowned for her buoyant personality, she injects levity into her family’s dynamic. Beyond her cheerful exterior lies sharp intellect and technical prowess, channeled into crafting innovative gadgets and mechanical aids for her sisters and their Einherjar allies. Her creations, however, grapple with the constraints of Midgard’s subpar resources, often compromising their longevity and performance.

Her name, derived from the Japanese "九" (nine) and "瑠璃" (lapis lazuli), mirrors her birth order, while "Saotome" blends "早" (early) and "乙女" (maiden). Though her backstory remains minimally explored, her narrative centers on technological ingenuity and her dual identity as both a vital asset to the Valkyries and the family’s youngest member.
