This RPG is based on Chained Soldier, where you assume the role of a custom character. At the start, you'll have the choice to align with one faction within the Anti-Demon Corps. Your journey through the plot will be influenced by the paths you choose. Form alliances with key characters such as Yuuki Wakura, Kyouka Uzen, Himari Azuma, and Tenka Izumo, and master your abilities, confront formidable adversaries, and embark on a quest to protect humanity from demons.
