"Medic-! Doc!" Corporal Ikoma, an Assault Armor pilot, was a medic. By the mid-21st century, demons had suddenly invaded Earth from another world, using humanoid mechanical weapons. In response, humanity developed their own humanoid armored weapons-Assault Armors-and successfully pushed the invaders back through the Gate to their own world. Ikoma, who had lost his hometown and family, volunteered for the military but was assigned the position that didn't carry a gun: a medic. Piloting the medic-type Assault Armor, he specialized in emergency repairs through part replacements, allowing his allies to return to battle. His comrades called him "Doc," and he remained dedicated to support. Yet, he had a personal vendetta against the enemy ace, the "Red Devil." As a medic, he couldn't fight directly. So what method of revenge did he choose...? Humanoid armored weapons race across the battlefields of another world. The war between Earth's forces and the otherworldly army-what fate awaits these soldiers? RELEASE: 2024 (ONESHOT)
