Fifty thousand soldiers of the god of darkness Vector, or Gabriel Miller, against a five-thousand-strong army of defenders under the command of the integrity knight Bercouli. Fanazio and the other integrity knights fight valiantly to overcome their outnumbered enemy, but the mountain goblins sneak behind the front lines and head to the rear. Young cadets Ronye and Chise, caring for the comatose Kirito, are in mortal danger. However, the most insidious strategist in the army of darkness is the head of the guild of black magicians Di I El, who hopes to destroy the entire army of defenders with one terrible spell... And where will Asuna, who has just entered the Underworld, go?!
