Failure Frame: I Became the Strongest and Annihilated Everything With Low-Level Spells (Manga) Vol. 12

ALL OUT WAR The Demon King’s army has finally arrived, clashing with the Sacred Alliance, a group of several armies that have bound together in a desperate attempt to push the demonic forces back. Zweigseed—a powerful general fighting for the Demon King—revealed a device that will call monsters from miles around. With the Northern Army already in tatters, they could not afford to fight on any more fronts. Fortunately, Touka and his Lord of the Flies Brigade arrived in time to turn the tide of battle. Now, Touka seeks to aid the Princess of Neah, the former master of his dear friend Seras. Meanwhile, his reunion with the other Heroes from Another World looms. Can Touka save everyone, or will those he cares for fall under the demonic onslaught?
