Chapter Summaries

After capturing Ultear, Aibo questioned her about Grimoire Heart’s plans and learned that Jellal intended to use Etherion to activate the R-System at the Tower of Heaven. Ultear also revealed that Grimoire Heart’s leader, Hades, was Fairy Tail’s former master Precht, and Aibo ended the interrogation to consider the revelations.

• Ultear told Aibo that she and Jellal had infiltrated the Magic Council to provoke it into firing Etherion.
• Aibo realized the Tower of Heaven was meant to absorb Etherion’s magic and complete the R-System, which Ultear said was Jellal’s plan to resurrect Zeref.
• Ultear explained that the R-System could not resurrect Zeref because he had never died, and said Hades had learned from him centuries earlier.
• Ultear revealed that Hades’s original name was Precht and that he had once been the second guild master of Fairy Tail.

After discovering how deeply Fairy Tail was connected to both legal and dark organizations, Aibo learned from Ultear that Jellal planned to use Erza as a sacrifice to activate the R-System. Aibo told Erza what he knew and began preparing to use the nearly completed Tower of Heaven to reveal Jellal’s intentions while avoiding harm to the hostages.

• Aibo sent Ultear back, then learned that Precht, the leader of Grimoire Heart, was Fairy Tail’s Second Guild Master and that the guild had powerful connections across Ishgar.
