Synopsis
Then he returned to the battlefield. But my friend, you are no longer alone. Wakamatsu Gale, a former human hero who changed from working in a cafeteria of an institution against "extreme creatures" to an instructor teaching the war against "extreme creatures". However, after a new battle, the shadows of further enemies are approaching those who are full of wounds ... Aim for the southern island? The situation certainly progressed between anxiety about the enemy who could not grasp the actual situation and a feeling of vacation. In the battle that finally occurs, Kazumi and Marie develop their talents and start a battle that the former heroes could not achieve-- !! In a world that has escaped the "campaign" with all the natural enemies of modern creatures = "extreme creatures", the battle between the new warriors who line up with the former heroes and the heroes who continue to show their great backs continues. It's a robot action that "updates" the next legend!
