Doors Of Chaos GN Vol 01 (Of 3) (MR)

Only the twins Clalisa (open) and Mizeria (close) control the Four Doors that protect the world from descending into chaos. When Rihitel, their guardian, kidnaps Clalisa, he weakens the Door of Chaos as demons begin to pour through and threaten to destroy the entire kingdom. Will Mizeria find her sister in time to restore order to the world?
