Riding the high from their latest level-up, the front-line fighters continue to Fort Sandras only to find a huge horde of powerful monsters waiting for them! Reinforcements from Aegis and Crest join the fight, but in the face of such overwhelming numbers, even the top guilds begin to crumble. Just as Misaki loses heart watching one comrade after another cut down around her, Theodore and Vampy suddenly arrive on Shuutarou s orders and turn the tide of the battle. However, something about Shuutarou s absence has Misaki feeling uneasy. His evil overlords have started showing themselves to players everywhere for the first time, but for what purpose? And where is their master?!
