In a war against demons for the fate of the world, even three chances at life may not suffice. Such is the fate of Lady Sacred Beryl, a divine maiden tasked with rooting out demonic corruption, only to be murdered and travel back in time -- twice. Upon her third attempt, Beryl realizes the truth: Her only hope to purify the realm is to face the fearsome House Vine, a lair of demons in mortal guise. Can Beryl survive in the domain of Duke Beleth von Vine, or will she find nothing but death and damnation once more?
