Chapter Summaries

Aibo discovered that his weak physique was limiting the growth of his magic power, so he sought a way to strengthen his body without relying on inefficient workouts. He asked Natsu to teach him Dragon Slayer Magic, and Natsu agreed despite warning that he could not teach it himself.

• Aibo noticed that his magic power was growing more slowly and learned from the guild master that his physique was too weak to contain more.
• Aibo rejected waiting for his body to mature and began looking for magic that could improve his physical strength.
• Aibo remembered that Dragon Slayer Magic could strengthen the body and decided to ask Natsu to teach him.
• Aibo offered Natsu multicolored flames, which Natsu eagerly ate, while Natsu and Gray resumed their usual quarrel.
• Aibo asked Natsu to teach him Dragon Slayer Magic, and Natsu agreed while warning that he might not be able to learn it.

Aibo discovered that Dragon Slayer Magic required a Dragon Seed and shifted his attention to experimenting with Enchant Magic. He used Mira to test its effects, leaving her eager to follow his orders despite the painful results.

• Aibo spent 1,000 Inspiration Points to raise Dragon Slayer Magic, which vanished and became Enchant Magic, Heteromorphic Magic experience, and an unexplained Dragon Seed count of zero.
• Mirajane rushed to Aibo’s house in tears after Elfman and Lisanna surprised her by secretly learning Take Over Magic for her.
• Aibo marked Mirajane’s guild mark with his Flying Thunder God mark and asked her to help him study magic.

• Mirajane fired a light-powered punch at a distant rock, then moved at high speed and shattered it before hurting her fist.
• Aibo excitedly proposed more experiments, and Mirajane agreed to obey his orders.

Aibo tested the many uses of LV1 Enchant Magic on Mira and objects, discovering that it could amplify abilities, imbue weapons, and enhance Word Magic. He forced Mira through exhausting experiments, then used telepathy to make her promise to help again while he finished developing new magic.

• Aibo enchanted Mira with elemental properties and found that the strength of each enchantment depended largely on her magical power and physical limits.
• Aibo enchanted swords, cards, a pen, and himself, using magic to create powerful weapons, spatial storage, automatic writing, flight, and meditation training.

• Aibo took Mira into the forest, injured her during experiments, and healed her with stored life force before sending her away exhausted.
• Mira tried to escape future testing, but Aibo used telepathy to tell her she could not leave until his new magic was complete.

Aibo developed an automated Word Enchantment system that tempered Erza’s body through alternating injury and healing, with Mira joining the experiments after competing with Erza. Three months later, Erza’s system worked, and Aibo began having his own physical data tested as Mira brought lunch and reported that Natsu had found a large egg.

• Mira returned to find Aibo conducting a body-tempering experiment on Erza and, after seeing Erza volunteer, agreed to undergo the painful trials too.
• Aibo teleported Mira and Erza to a forest laboratory, where the two argued over who was Aibo’s closest big sister before agreeing to compete in enduring the experiments.

• Erza tested the completed system and confirmed it worked, while Aibo asked her to begin testing his physical data for a system suited to his weaker body.
• Mira arrived with lunch using a one-way teleport card and told Aibo and Erza that Natsu had found a huge egg he believed was a dragon egg.

Aibo endured the painful effects of his new body-tempering magic and discovered that it was recognized as a new magic skill. After finding a mysterious egg and opening the box left beside it, he received a Dragon Seed and the first level of Dragon Power.

• Aibo cast his body-tempering magic on himself, suffered intense pain, and saw his maximum stamina increase.
• Mira teased and squeezed Aibo while Erza tried to intervene, and Aibo fled to his room without his shirt.
• Aibo recovered and discovered that [Body Tempering LV1] had changed into [Body Tempering Magic LV1: 96.7%].
• Aibo found an egg, a box, and a letter from a mysterious person who asked him to care for the child temporarily.
• Aibo opened the box, and its light merged into his chest, prompting his system to display [Dragon Seed: 1] and [Dragon Power LV0: 1/1000].

Aibo discovered that the Dragon Seed let him devour spatial energy and speculated that it came from a Time-Space Dragon, though he planned to call his power Light Dragon Slayer Magic. After Erza apologized for damaging his clothes, Aibo shared lunch with her and Mira and told them about the mysterious pink egg, which they took to the guild to compare with Natsu’s egg.

• Aibo tested his new Dragon Slayer Magic and found he could devour spatial energy released by teleporting, as well as a small amount of light.
• Aibo guessed the Dragon Seed came from a Time-Space Dragon and decided to call his magic Light Dragon Slayer Magic in public, then learned he could not devour his own magic power.
• Aibo examined the mysterious pink egg and resolved to raise whatever hatched from it.
• Erza arrived to apologize for hurting Aibo and ruining his clothes, while Virgo and Mira brought him lunch.
• Aibo told Erza and Mira about the egg, and they returned to the guild together to compare it with the egg Natsu had found.

Natsu brought a patterned egg to the guild, where Aibo helped him build a nest with magic to keep it warm and humid. Lisanna offered to help hatch it, while Aibo kept his own egg separate and out of Natsu’s reach.

• Mira, Erza, and the others examined Natsu’s egg, and Natsu decided it was a dragon egg because of its shell pattern.
• Makarov warned Natsu not to use violent magic to hatch the egg, and Lisanna suggested keeping it warm.
• Natsu breathed fire on the egg, but Aibo explained the need for controlled warmth, humidity, and occasional turning.
• Aibo built a nest and magical temperature and humidity controls near his home, and Natsu placed his egg there for the group to help hatch.
• Lisanna revealed her Animal Soul Takeover and agreed to help care for Natsu’s egg, while Aibo said he would keep his own egg at home.
• Elfman watched Lisanna and Aibo receive admiration, then clenched his fist and made a decision.

Aibo helped Elfman understand that his limited Take Over was tied to his lack of confidence, then agreed to train him toward becoming the guild’s strongest. Cana and Levy also cornered Aibo into making plans with them, leaving him committed to a magical-beast trip and a cosplay contest next month.

• Elfman asked Aibo for help with his inability to perform a full-body Take Over, and Aibo identified his lack of confidence as the obstacle.

• Aibo used a Thought Projection to ease the pain of his body-tempering training while his original body worked at the guild.

• A blue winged cat emerged from Natsu’s egg, and Natsu named him Happy.
• Aibo hurried home and helped his struggling pink egg hatch, revealing a cat who called him “Mommy.”
• Aibo taught the kitten to call him “Boss,” named her Ailu, and asked Virgo to buy milk and a magic refrigerator.
• Aibo told Ailu to learn cooking, housework, and trapping so she could take care of him and hunt magical beasts with him.

Aibo trained with Erza and discovered that his ability could record martial techniques, then chose the spear because his skill with it improved fastest. He prepared to hunt magical beasts with Cana and Ailu, leaving Cana to wonder whether she was merely tagging along on Aibo and Ailu’s adventure.

• Erza sparred with Aibo, whose spear technique improved quickly and made him eager to explore martial skills.
• Erza offered to have a magical spear forged for Aibo and invited him to train in Knight Magic, while Cana insisted that he belonged to her and Levy’s Book-Loving Squad.
• Ailu brought Aibo a towel, and he praised the young cat’s intelligence and innate Wing Magic.
• Cana worried about bringing newborn Ailu on a magical beast hunt, but Aibo reassured her that his teleportation magic would let them escape and return to Magnolia at night.
• Cana agreed to leave the next day, and Aibo and Ailu excitedly declared themselves Monster Hunter partners, making Cana suspect she was the extra member.

Aibo, Cana, and Ailu set out from Fairy Tail to hunt magical beasts, and Aibo tested his strength against a Mountain-Splitting Beast. After defeating it with his enhanced spear, Aibo discovered that fighting increased his inspiration.

• Aibo said goodbye to Erza, Cana, Levy, Mira, and the others before teleporting with Cana and Ailu to a village near a snowy mountain.

• Aibo checked his depleted stats and gained 666 inspiration, realizing that fighting could help him gain experience.

Cana completed a five-star Mist Deer card and refined her sacrifice-based summoning system with Aibo’s guidance. As the siblings hunted deeper into the forest, Aibo sensed a powerful entity at an unfamiliar wizard guild settlement that had invited him inside.

• Aibo revealed that he had learned Light Dragon Slayer Magic from Natsu and asked Wendy to teach him Sky Magic.

After Wendy joined Fairy Tail, Aibo became her guardian and began learning Sky Magic from her. Discovering that her healing magic used a restorative form of positive energy, he gained Sky Magic and wondered whether the church’s lost healing arts and the disappearance of the gods were connected.

• Rob made Aibo Wendy’s nominal guardian and paid him with a book on soul magic, which rapidly increased Aibo’s Soul Magic experience.

• Aibo used Inspiration to gain Sky Magic LV1 and speculated that the church had once mastered this healing energy before the gods vanished.

Aibo reflected on his slow progress with Sky Magic and Meditation before preparing for a date with Levy at the amusement park. When Levy’s romantic praise earned Aibo a surge of Inspiration Points, he began to suspect he had misunderstood how to use his system.

• Aibo found that others could not learn Sky Magic and considered spending Inspiration Points to improve it, though he was saving them to level up Meditation.
• Aibo agreed to attend an amusement park competition with Levy but secretly arranged for Lisanna to bring the others along.
• Levy arrived expecting a date with Aibo, only to find Natsu, Cana, Erza, Mira, Lisanna, and Wendy joining them.
• The group entered the amusement park, and Levy tried to treat the outing as a group trip instead of a date.
• Levy praised Aibo and teased him when he blushed, earning him 6,666 Inspiration Points and prompting him to question how he had been using the system.

Cana struggled with jealousy at the thought of Aibo growing up and starting a family of his own, while Aibo tested whether affectionate attention could earn inspiration points. His experiment with Virgo earned enough points to upgrade Meditation, but the upgrade immediately made him faint.

• After the shuriken contest, Cana wondered whether she could accept Aibo finding a lover and feared losing her closeness with him.
• Aibo blamed his system for rewarding romantic inspiration and decided to test its method with an older woman.
• Aibo asked Virgo for a hug, then learned that her serious personality was a service-oriented adjustment rather than her true self.
• Virgo returned with her genuine masochistic preferences and asked Aibo to whip her, earning him inspiration points as he complied.
• Aibo used the points to raise Meditation from level three to level four, then fainted.

Aibo woke after three days unconscious from Meditation autonomously absorbing magic power and raising his maximum reserves, and Porlyusica and Makarov advised him on managing the dangerous growth. Porlyusica revealed that Grandeeney had left a message for Wendy, while Aibo worried that the girls had learned about his private encounter with Virgo.

• Cana told Aibo that he had collapsed and that Virgo had carried him back to the guild.
• Porlyusica explained that Aibo's uncontrolled Meditation had caused severe magic power saturation, so Aibo created a giant iron construct to expend some of his magic.
• Aibo discovered that Meditation had raised his maximum magic power above 5,000 while he had been unconscious for three days.
• Makarov urged Aibo to control Meditation, strengthen his body, and study Form Magic to handle his growing magic power.
• Porlyusica asked Wendy to stay and told her that Grandeeney had entrusted her with something for a Sky Dragon Slayer.
• Aibo worried that the gathered girls might discover his encounter with Virgo and resolved not to lend Virgo to anyone again.

After Aibo learned Virgo could sense his mature soul and discovered more about Celestial Spirits, he decided to keep her summoned by his side. The chapter ended with Aibo ordering a magic experiment on Virgo, who eagerly agreed.
