Chapter Summaries

Aibo learned from Lullaby that Zeref created the Demons of Tartaros, who used negative emotions as energy, and considered how their power might help his Gugas.

After an embarrassing incident left Aibo and Erza avoiding each other, Erza questioned whether her feelings for him were only those of an older sister. Aibo returned to guild life and research, while Laxus came back with the Thunder God Tribe.

Aibo learned more about Lyon and Gray’s history, then prepared to pit Lyon’s group against Natsu and Gray on Galuna Island. Natsu’s team found Deliora and discovered Lyon was using the purple moonlight to undo Gray’s master Ur’s seal, setting up a fight between the former disciples.

• Lucy reported the group’s discoveries on Galuna Island, while Aibo reflected on Lyon, Gray, Ultear, and Ur’s past.

• Aibo remotely controlled the Gugas and watched Natsu’s one-sided beating from the sky.

• Natsu, Lucy, Happy, and Gray were captured after the Seven Sin Apostles defeated them, and Lucy recognized Aibo when he appeared disguised as the Love Emperor.
• Aibo led the group to Deliora’s seal, where Gray tried to persuade Lyon to abandon his plan to kill the demon.
• Aibo revealed that Deliora was already dead, drew black and white information from its body and Ur’s ice, and watched the demon crumble to ash.
• Aibo discovered that the white information contained Ur’s memories of loving Ultear and passed those memories to her.
• Ultear ran away in tears, while Aibo asked the captive Natsu and Gray how he should deal with them.

Aibo explained how to destroy the Purple Moon and revealed that the islanders were a distinct magical race whose memories had been altered by it. After restoring the moonlight and helping the villagers recover their memories, he left the rest of the request to Natsu and the others and headed off to check on Ultear.

• Natsu and Gray suspected Lucy had known Aibo's identity, but she changed the subject by reminding them that the Purple Moon still needed to be destroyed.
• Aibo explained that a crystalline membrane of evil energy turned the moonlight purple, then asked Lyon and his group about their plans after Deliora's death and offered them work producing Moon Drops for Fairy Tail.
• Aibo took Natsu's group to Demon Village, gathered the villagers' blood for examination, and pierced the membrane above the island, restoring the moon's normal light.
• When the villagers remained in demon form, Aibo explained that they had always been a magical race and that the Purple Moon had confused their memories; the chief and villagers then remembered who they were.
• Aibo told Natsu and the others to handle the rest of the request and left to check on Ultear, ignoring their attempt to discuss the photos.

Ultear broke down after learning the truth about her mother, and Aibo stayed with her as she grieved. He suggested that his future self might have traveled back in time and saved Ur, leaving Ultear hopeful and promising to trust him.

After learning the scale of Phantom Lord’s forces, Aibo persuaded Fairy Tail not to rush into a full attack and decided to retaliate against the guild’s provocation. He teleported the iron pillars Iron Dragon had used to attack Fairy Tail high above Phantom Lord’s headquarters and watched them fall.

• Fairy Tail’s members complained about Makarov’s refusal to strike back, while Aibo, Erza, and Mira each suggested killing Phantom Lord in increasingly extreme ways.
• Aibo used the Ancient Grimoire to reveal Phantom Lord’s four elemental S-Class wizards, Iron Dragon Gajeel, Guild Master Jose Porla, and their massive membership and magical fortress.
• The guild members agreed that Phantom Lord was too powerful to attack recklessly and discussed calling Laxus or Gildarts back.
• Aibo teleported the iron pillars from Fairy Tail’s entrance to a point ten thousand meters above Phantom Lord’s guild and used Light Telescope to livestream their fall.

Aibo hosted a party where the girls discovered the Seven Sins Guga and confronted him over their names, prompting him to flee and focus on studying Deliora’s Demons knowledge. His research connected the knowledge to Fairy Law and led him to unlock Life Magic, which he began investigating.

• Erza resumed speaking comfortably with Aibo, then reprimanded Lucy and the others for accepting an unauthorized commission to Galuna Island.
• Lucy revealed Aibo’s seven new Gugas, and the girls demanded that he beautify the ugly penguin-like creations.
• The seven people whose names matched the Gugas’ sin codenames confronted Aibo, so he left the Cake Tower and teleported away.
• Aibo studied Deliora’s Demons knowledge and discovered that a creation could only possess abilities its creator had.
• Aibo recognized that Deliora’s knowledge resembled Fairy Law and gained Life Magic, then decided to test the new magic through his own research.
