With the daemonic incarnations running rampant and turning innocent bystanders into monsters, it's up to Allen and the No-life Gamers to take care of them and save the people from imminent doom. Beast Princess Shia and her army of beastkin soldiers agree to help, though the princess divulges her struggle to activate Beast Mode. She's not the only one getting antsy either, as Dogora also bemoans his futile efforts to use his Extra Skill. All the while, Allen and his party find a mysterious floating island where three powerful Demonic Deities--including the Great Pope and Falnemes, the Goddess of Arbitration--await him. Can Allen unravel the secrets of the mysterious island? Just what are the Demon Lord and his army planning? And will the Gamers emerge victorious from this devastating battle?
