From the CMX manga:
The best-selling title by blockbuster new talent Sanbe Kei (Kamiyadori)! In a dark future, rival warriors of warring sects persecute nonbelievers and die for their faith. But a disillusioned young novice and a deadly gun-toting priest may be about to change all that…
Young Capria has completed her studies at the Arsenal School and has begun her internship with the Elysia Unification Council under Father Garrincha. But no lessons could prepare this sheltered novice for the outside world, where rebels battle against the dreaded "Testarotho." Heretics are tried and burned at the stake, warring religious factions battle for power, and the common people live a miserable life in feudal servitude. Can she bring a spark of hope to a world filled with destruction and madness? Maybe if she lives long enough!
