As they travel across the war-torn land, they are confronted by avatars in the service of multiple nations, and Arca - a cult made up of avatars led by a woman known as Mathias. Chitose joins Arca to further their cause of a utopia for avatars, and tries to persuade Luca to join, causing a rift between them. The conflicts between the groups is further inflamed as more people regain their memories as warriors of Sensus or Ratio, sparking old conflicts. In their adventures, the group works to end the fighting and learn about their past lives. When the full truth is revealed, they decide to fulfill Asura's wishes and unite the two worlds. This brings them into conflict with Mathias, who is revealed to be the incarnation of Asura's wrath at being betrayed, and now wishes to destroy both Devaloka and Naraka. Chitose, consumed by Sakuya's love for Asura, helps Mathias in her task. The party confront Mathias and Chitose in Devaloka's ruined capital, where the Manifest is hidden. They defeat Mathias, and Chitose kills herself in a fit of despair. Luca then proceeds to use the Manifest to merge Devaloka and Naraka, nullifying the avatars' powers and lessening the chance of future conflicts. The group then returns to their normal lives.
