What Greville told him was a reality more horrifying than anything he could have imagined. The identity of the new threat to this world - "Necrostar". A fragment of a cosmic monster, the "Necrostar" destroyed the common sense of magic and brought the dead back to life one after another, regardless of whether they were demons or humans. Matthias is told that even the strongest group of ancient serial and indiscriminate killers, the "Masters of the Art of War," have been resurrected, and he immediately sets out to destroy them...?
