Hell Mode, Vol. 4: The Hardcore Gamer Dominates in Another World with Garbage Balancing

Diving straight into the Rohzenheim War! Rohzenheim, nation of the elves, is under attack by the Demon Lord Army and on the verge of total annihilation. Heeding the requests of his home country and Sophialoneh—crown princess of Rohzenheim and No-life Gamer newcomer—Allen and his companions decide to join the fight and save the elves. When they land on the elven continent, however, they find the capital already fallen, the front line on the verge of crumbling, and one of the few remaining cities overflowing with wounded and refugees. To make matters worse, they learn that the enemy’s top general is a Demonic Deity who has already defeated Hero Helmios before! The Demon Lord Army is far more numerous and much more powerful than anything they’ve ever encountered before! Can the No-life Gamers truly prevail against a force of three million?!
