After defeating the monster and the boss, the group seeks refuge in the basement where they stumble upon Riberia's younger sister, Brandy. They learn that Hakan made a contract with the devil Mammon to gain power. Furthermore, they discover that the environment within the basement alters the body, causing even minor injuries to heal extremely slowly, leading to tension as a party member lays critically injured. This chapter also introduces more about the unique world and its probability-manipulating nature.
