Casebook of Kurumi Tokisaki, Magic Detective

Kurumi Tokisaki, a college student with a dark past, works as a detective specializing in crimes involving magical artifacts. A magic bullet fired from an impossible angle, a living doll mixed up in a series of comas, an absurdly expensive meal said to restore one's youth, and a doppelgänger spotted at an all-girls school after an attempted suicide. Magical artifacts make the impossible possible, but Kurumi won't let that stop her from solving the case! (Source: Yen Press)
