Mahou Shoujo Ikusei Keikaku: ACES

A clash of magical-girl titans! Snow White, a.k.a. the Magical-Girl Hunter, is searching for her dear friend Ripple when she's summoned by one of the Three Sages, the Magical Kingdom's highest authority. The Sage asks Snow White to locate a missing magical girl-a simple enough task that ends up throwing her into the middle of a bloody war between two opposing Sage factions. Meanwhile, Princess Deluge is on the warpath, hell-bent on avenging her fallen comrades...which puts her and Snow White's allies in conflict! (Source: Yen Press)
