There’s a vicious struggle raging in the heart of the Orthodox Church. Athos and Adept, two ancient factions, are locked in a conflict that has lasted for thousands of years. To them, nothing is forbidden and everything is a weapon to be used in their fight for the Circuits, from faith and politics to mercenary death squads and even the feared Qwasers, powerful fanatics that take holy breast milk from their designated Marias to fuel violent miracles. Aleksandr Hel is a young Russian Athos-raised Qwaser who’s sent to Japan to eliminate a growing heretic threat. But there he meets Oribe Mafuyu and Yamanobe Tomo, two girls who know more than they should, who make Aleksandr question his reasons for fighting -- and who are soon trapped in the secret war that’s followed in his footsteps.
