In the port town of Liber, the "drug" incident occurs. After successfully executing the culprit, Manon Liber, Menou faces the onslaught of the Four Great Human Disasters, known as ≪Pandemonium≫, which once nearly brought about the world's destruction. Surrounded by monsters that are infinitely spawned from her own body, a physical form that dies and revives repeatedly, and a malevolence that treats life and death as mere entertainment, Menou finds herself cornered. Just as she braces for death against the overwhelming assault of the master of Pandemonium, that princess knight appears――. This is the fifth volume of the highly popular series that won the GA Bunko Grand Prize, featuring a tumultuous and thrilling comic adaptation.
