After voting off Mister Negative and Hector Barbossa, who would later be revealed to be innocent of being a Traitor, much less responsible for the murder of Frank Castle, the group would later encounter the mastermind of the Murder Game himself, Fiamma of the Right. Demonstrating his mighty power, he did away with Sean Grant and Edipsu, as well as the overseer of the Church, Kirei Kotomine. Showing off the power of what he called the Right Hand of the Crimson Moon, he sent everyone into a strange, parallel world that was devoid of life, except for strange creatures that proved to be quite hostile.
Those who would go into the Core would fight off a number of said hostile creatures, before encountering a cube that claimed to be the center of the world they were in. It would open itself up after presenting a few questions, but when it would do so, it would turn out that further interaction was impossible with it, though it could be observed that the cube was corrupted by some unknown force at work.
As for the Arena, those who would enter would come into contact with a young man named Touma Kamijou, who claimed that if he could find it, he could destroy the core and get everyone present out of there. However, before he could say more, he would be taken captive by a strange girl, who was dangerously in love with him, to even a murderous extent. Before long, though, the group would be able to defeat the girl and free Touma from his prison.
Meanwhile, in the Academy, the group would come into contact with an old man named Kischur Zelretch Schweinorg, who claimed to be capable of traveling through worlds freely through a power that he called the "Second Magic," though here, he was unable to travel out because he was apparently bound by something, and he was determined to find out. With the group fighting through the Academy against hostile forces, they would discover that the center of the world was the cube located in the Core, and destroying it would yield unknown results.
In the Afterlife, the man who called himself Kouma Kishima would spar with Frank and Minato, speaking of the phenomenon known as the TATARI, and how it was connected to the Murder Game, which in turn was partially sparked from the evil of the Holy Grail, the object sought after in the Holy Grail War that Illya and Rin had been preparing for for quite a while. With that, Illya resolves to find a way to destroy the Holy Grail and put an end to the Murder Game. After resting up, they would find that Kishima was suddenly gone the next day.
When they would start traveling again, Illya's body began to surge with the power of the Right Hand of the Crimson Moon, a result of Fiamma of the Right's display of power. Using it, she would send Frank Castle back to the world of the living, but shortly afterwards, her power would malfunction and send her, Robin, and Minato into a woman's dormitory in England, where Kaori Kanzaki and a number of other nuns lived.
