Slay monsters with a red-haired swordswoman! Battle and romance await.
At the foot of a massive mountain towering over a vast wasteland lies the fortified city-state of Rokka, built as if to embrace the steep, rugged cliffs. A single river flows from the mountain into the city, serving as a vital lifeline in this barren land. Outside the city walls, giant "Shell-Beasts"—monsters with massive carapaces and many legs—lurk and occasionally swarm the city in hordes. To counter this threat, humanity formed the defense organization "Aegis." Guest and Shiki are members of Aegis's 3rd Mobile Unit. They roam the Rokka Frontline, protecting the city and their comrades from the encroaching monsters. Whether you focus on slaying Shell-Beasts or living a free life within Rokka is entirely up to you.
