The Ichinose broke away from the Hiiragi family's Order of the Imperial Demons five centuries ago, and the price set then is still being collected: every Ichinose heir spends his school years inside a Hiiragi institution being ground down. Guren Ichinose is sixteen when his turn comes at First Shibuya High, where a sorcerer of his rank has to take beatings from classmates without answering. Mahiru Hiiragi, who will inherit the Order and who knew him as a child, notices him anyway. This manga adapts Takaya Kagami's prequel light novels.
