GRANBELM

Centuries ago, magic was a common force that brought prosperity until it fueled devastating wars. To restore peace, seven legendary mages sacrificed themselves to seal all magic away. Nearly a thousand years later, their seal, Magiaconatus, holds Granbelm-a monthly tournament where participants fight to claim the title of Princeps, the sole true mage. During a full moon, high schooler Mangetsu Kohinata is abruptly pulled into a dreamlike world where six mages are battling in Granbelm. Mistaken for an enemy, she's nearly killed until Shingetsu Ernesta Fukami and her Armanox, Viola Katze, save her. But when Shingetsu is attacked for shielding Mangetsu, Magiaconatus bestows upon Mangetsu her own Armanox, White Lily, which she uses to drive off the assailant. Stunned by this hidden world of magic and conflict, Mangetsu chooses to stand by Shingetsu in Granbelm, determined to help her achieve her wish.
