The No-life Gamers find that everything is not well in the Prostia Empire. As he scrambles to unlock a new Summon and rig the Songstress Contest to obtain new gear, Allen struggles to find any trace of Beast Crown Prince Beku—the man who incited a failed rebellion against his nation and was forced to flee. After Allen and his friends split up, each tending to their own tasks, Allen notices that his merchant friend, Pelomas, is missing! Where could he have gone?! Was he just wandering about, or was he abducted? Time is not on Allen’s side. If the effects of Mimic wear off on Pelomas, he will transform back into a human and drown in the underwater empire! This already awful situation takes a turn for the worse when Allen is stopped by the Demon Lord himself! Why is the Demon Lord here anyway?! Can the Summoner save his friend? Or will Pelomas meet a grisly, hellish end without proving his devotion to his beloved Fiona?
