Chapter Summaries

Aibo discovered that a blonde guild member named Lufei and an adult Erza had returned from five years in the future using the magic book Memories of Time. Erza asked Aibo to decipher the book and warned him against pursuing multiple romantic relationships, though he misunderstood what she meant.

• Aibo grew suspicious of Lufei after overhearing her thoughts about young guild members, Natsu, Gray, and Erza.
• Aibo sensed two Erza marks and teleported to find adult Erza in a Catgirl outfit, struggling to read a magic book.
• Erza revealed that she and others had traveled five years into the past with Memories of Time and asked Aibo to help them return.
• Aibo took the book, felt an unusual hunger for it, and summoned Virgo to bring Erza clothes.
• Erza warned Aibo to take love seriously and never deceive anyone, while Aibo mistakenly thought she was forbidding his planned Fragrance-Stealing Plan.

Aibo deciphered the Memories of Time book and learned that it would return everyone to their original time after six hours. As Erza tried to avoid revealing more about the future, her accidental hints inspired Aibo to invent a magical telescope, which showed Natsu and Gray fighting their younger selves by the river.

• Little Erza mistook adult Erza in a Catgirl outfit for a suspicious stranger, then left to confront Mira after realizing she had wrongly blamed Natsu and Gray for her missing cake.
• Aibo deciphered Memories of Time and discovered that the book sent its opener to a remembered time and place for six hours before returning them to their original time.
• Erza worried about finding everyone before the time limit, and Aibo used spatial coordinates to locate Natsu, Gray, Lucy, and the others.
• Erza accidentally mentioned the Telescope Technique, prompting Aibo to combine light and spatial magic to create a Light Telescope Technique.
• Aibo used the telescope to spot Natsu and Gray enthusiastically fighting their younger selves while Happy watched, and Erza feared others would learn that she inspired Aibo's inventions.

Aibo watched Erza and the others return to their own time, then treated the younger Natsu after the future Natsu injured him. Left holding Memories of Time, Aibo discovered he could absorb its time-space energy and wondered how the book’s existence affected the timeline.

• Aibo practiced Light Telescope Magic and Snapshot Card Magic with Erza, recording the two Natsus and Grays fighting for her.
• Erza said goodbye to Aibo and warned him not to appear before the group again to avoid a time-space paradox.

• Aibo healed the younger Natsu’s neck wound, but a scar remained because the injury came from Dragon Slayer Magic.
• Erza and the others vanished in a flash of light, leaving Memories of Time behind for Aibo to find.
• Aibo ate some time-space energy leaking from the book, raising his Space Magic and Time Magic experience, then stopped to avoid damaging it further.

Aibo struggled to advance his Time Magic and asked Makarov about learning more time spells. Makarov suggested Ancient Grimoire and arranged for Aibo to enter the Magic Academy through a Thought Projection under a new identity.

• Aibo found that his Time Magic experience had barely increased, and he could only use Reparo to restore damaged objects.
• Makarov told Aibo that Fairy Sphere was the guild's only other magic connected to time, but it was reserved for S-Class mages.
• Makarov suggested Ancient Grimoire, a magic for storing and sharing magical knowledge, but admitted that no one in the guild knew how to teach it.
• Makarov recommended that Aibo enroll in the Magic Academy, where he could learn Ancient Grimoire.
• Aibo proposed using a Thought Projection to attend the academy and chose the name Aibo Hanna for his enrollment.

Aibo learned that a paperwork error had enrolled him at the Magic Council School as Hannah Aibo, a female student, but accepted the identity so he could study Archive Magic. As the academy term approached, he prepared a Thought Projection with restricted abilities and debated how to present himself.

• Makarov told Aibo that the academy had issued his admission notice under the name Miss Hannah Aibo and could not change it.
• Aibo agreed to attend under the mistaken female identity after learning he did not have to pretend to be a girl.
• Aibo trained for months, raising his maximum magic power above seven thousand and developing Time Magic that sent inorganic objects into the future.
• Aibo prepared a Thought Projection with most of his magic power, limited it to Word Magic and Ice Magic, and barred it from using several abilities that could expose his identity.
• Aibo decided he would embrace both sides of the identity, though he remained unsure whether to transform into Hannah Aibo.

Aibo sent his Thought Projection to the Magic Academy under the name Hannah Aibo, hoping to pass as a girl, but nobody questioned his gender. He earned an S-Class rating and was assigned Ultear Milkovich as his roommate, who still refused to believe he was a boy.

• Aibo used most of his magic power to make his Thought Projection look more feminine and left Magnolia after Makarov sent him to the Magic Academy.
• Aibo traveled to the academy near Crocus and registered as Hannah Aibo without anyone questioning his gender.
• Jellal Fernandes and Ultear Milkovich each earned S-Class aptitude ratings during the magic-power test.
• Aibo also received an S-Class rating and was placed in Class One.
• Aibo discovered that Ultear Milkovich was his roommate and told her he was a boy, but she dismissed it as a joke.

Aibo learned that he would need to rank first at the Magic Academy for three consecutive years to gain access to Ancient Script Magic, so he resolved to dominate the exams despite his classmates mistaking him for a girl. At the library, he encountered Ultear, whose interest in Time Magic and strange suspicions about him led her to invite him to talk.

• Aibo grew frustrated with the girls who admired him as a handsome girl and decided to focus on leaving the academy as soon as he learned Archive Magic.
• Aibo discovered that students needed top-ten exam results for two consecutive years to study Archive Magic, while first place for three years offered a chance to study Ancient Script Magic.
• Aibo committed to staying at the academy and ranking first for three years, then crushed his classmates in tests with near-perfect scores.
• Aibo noticed that Ultear seemed to lead Siegrain while he pursued influence in the Magic Council and she spent her time reading in the library.
• Aibo met Ultear while they reached for a book about Time Magic, and she invited him to discuss magic with her; he accepted.

At the Magic Academy café, Ultear discovered that Aibo knew about time travel and had memorized a spell model for returning to the past. She became eager to learn from him, leaving Aibo curious about her hidden ties to Grimoire Heart, Zeref, Hades, Brain, and Jellal.

• Ultear asked whether Aibo planned to join the Magic Council, and he said he only wanted to study magic.
• When Ultear asked about magic that could return to the past, Aibo said he had met someone from the future and rewound an overturned cup with Arc of Time.

• Aibo explained that he knew the complete spell model for returning to the past, though it was difficult to use.
• Ultear sat beside Aibo, linked arms with him, and declared they were destined to be best friends, dismissing his reminder that he was a man.

Ultear pressed Aibo for access to Memories of Time and a way to activate Return to the Past, but Aibo explained what the magic required and urged her to stop sacrificing herself to her regrets. After Hades confirmed the same conclusion, Ultear believed Aibo and became devoted to maintaining their friendship, leaving Siegrain surprised by her priorities.

• Ultear pleaded with Aibo to let her examine Memories of Time, while Aibo refused and challenged her to explain why she wanted to return to the past.
• Aibo told Ultear that Return to the Past required enormous magic power, the power of time and space, and an ultimate understanding of time, and he urged her to share her story instead of making demands.
• Ultear apologized to Aibo and thanked her, but Aibo retreated to his room and left her worried that their friendship had suffered.
• Ultear consulted Hades about the Return to the Past magic model and received a conclusion similar to Aibo's, after which she believed him and began following him around.
• Siegrain asked Ultear to contact Brain about living equipment for the Tower of Heaven, but Ultear told him to contact Brain himself because she did not want Hannah to misunderstand.

During his vacation, Aibo traveled across Fiore and went to investigate Juvia, a girl whose magic caused constant rain. After her emotions triggered a flood, Aibo stopped the rain with his Giant of Light transformation, leaving Juvia mesmerized.

• Juvia watched the rain stop and stared at the Giant of Light in awe.

• Juvia packed a small bundle, stored it inside her body, and traveled with Aibo through Spatial Magic to the guild.
• Aibo brought Juvia into Fairy Tail and welcomed her as the guild members greeted them.

After studying Juvia’s Water Magic, Aibo speculated that LV6 skills might belong to the gods of the past and wondered whether his system could let him reach that realm. He left himself excited about the possibility of becoming a god after saving enough Inspiration Points.

• Aibo theorized that the gods of the past had possessed LV6 skills and that dragons had once surpassed them.
• Aibo estimated that raising a skill from LV5 to LV6 would cost one hundred million Inspiration Points, which he could save in about 160 years.

Aibo planned to strengthen his magic before Natsu and Gray challenged him to a fight, believing they could finally get revenge on him. Aibo agreed to battle them both at once, and the guild gathered to watch as he prepared to begin.

• Natsu and Gray accepted the wager, and the guild cheered them on while Aibo checked his status and prepared to fight.

• Cana and Mira argued over who had taken care of Aibo and who would look after him, but Aibo reassured both sisters and stopped their quarrel.
• Cana left after apologizing, and Erza and Levy said they were concerned about her secret drinking; Aibo offered to handle the problem and invited everyone to his house.

• Juvia asked Erza whether she liked Aibo and concluded Erza was too unaware of her feelings to be a threat.

• Hannah Aibo asked Ultear what she would do if someone she liked left her, then admitted he feared losing some of the girls he cared about.
• Ultear suggested capturing and training anyone who tried to leave, and Hannah decided he would stop being passive and face the problem directly.

• Hannah explained that a mage capable of elementalizing their body as ice might theoretically restore an Iced Shell caster, but too much time could leave only a corpse.
• Ultear worried that time would defeat her efforts and wondered whether to continue the Moon Drop plan.

Aibo’s Body Tempering Magic and Word Magic reached LV4, leading him to discover a Second Magic Source that could let mages store more magic without straining their bodies.

• Virgo explained that Leo had defied the Celestial Spirit World’s laws after refusing to serve abusive owners, and that he would lose his memories when his remaining energy ran out.
