Toma pursues Hyoka but encounters Sherry instead and is forced to fight her. He learns Sherry once had a friend named Ellis who was an Esper who was involved in an experiment between Necessarius and Academy City to create the first Esper/Magician Hybrid but suffered from the experiment and was killed by Knights as the experiment was a violations of the truce between science and magic; to prevent this tragedy from occurring again, Sherry intends to divide both sides forever through conflict. Outraged that Sherry does not believe that people who are different like Index and Hyoka could be friends, Toma successfully defeats Sherry. However, doing so results in Golem Ellis above ground losing control, and Index is cornered until Hyoka suddenly appears and destroys the Golem each time it reforms. After Toma arrives to deliver the finishing blow, Index and Hyoka reconcile just as Hyoka fades away to the Imaginary Number Sector. Meanwhile, Tsuchimikado confronts Aleister upon realizing the later was behind the whole incident all this time to test the Imaginary Numbers Sector and warns him that Toma will be his enemy if he keeps using him. As each of the characters settle back into their daily lives, Stiyl meets with the Archbishop of Necessarius, Laura Stuart, who decides that Necessarius will need Index and Toma's help for an upcoming problem as Kaori is missing in Japan after the events of the Angel Fall.
