Power Progression

Stage / Realm / Level	Chapter	Notes
Telepathy Magic LV4	1 3	Awakened during his capture by a Dark Magic Cult; sent a distress signal over ten thousand meters to Gildarts, but initially could not stop passively hearing thoughts within roughly one hundred meters.
Meditation LV1; Crush Magic LV0	3	Learned from Gildarts; Meditation established his method of training magic power, while Crush Magic remained unmastered.
Requip Magic LV1	7	Self-taught rather than force-upgraded; could change clothes within five kilometers of his Requip doll.
Crush Magic LV1	7	Raised with Inspiration Points after a destructive riverbank test; the forced upgrade left the spell difficult to control.
Shaping Magic LV1	12	Drawing Magic was invested with 1,000 Inspiration Points, then disappeared and merged into Shaping Magic.
Space Magic LV1	14	Formed when Teleportation Magic reached completion and merged with Requip Magic; Aibo identified spatial magic as his best compatibility.
Meditation LV3	24	Force-upgraded with over 100,000 Inspiration Points; doubled its magic-capacity effect and allowed meditation to restore mental energy and mana.
Transformation Magic LV2	35	Could alter his appearance, physique, and clothing, including assuming the form of a teenager.
Space, Word, Magic Power Control, and Light Magic LV3	41	These became his principal developed combat and utility magics, alongside Telepathy LV4 and Meditation LV3.
Enchant Magic LV1	42	Obtained when an attempted forced upgrade of Dragon Slayer Magic converted into Enchant Magic and produced a dormant Dragon Seed.
Body Tempering Magic LV1	45	A self-created magic recognized by his system; increases base physical attributes, though its early use caused severe pain.
Dragon power LV1	46 74	After receiving a Dragon Seed, he gained the ability to devour light and space elements, suggesting Space Dragon Slayer Magic; progress remained slow due to the scarcity of those elements.
Meditation LV4; Body Tempering Magic LV3	60	Meditation’s autonomous activation pushed his magic capacity beyond 5,000. Aibo then prioritized body tempering to keep his physique and magic control stable.
Body Tempering Magic LV4; Word Magic LV4	78	His body approached a “perfect” state, with greatly enhanced vitality and resilience; Word Magic provided the understanding needed to refine his customized body-forging techniques.
Second Magic Source	78	Discovered an additional internal magic source, increasing his capacity for storing and growing magic power.
Space Magic LV4; Archive Magic acquired	82	Reached Space Magic LV4 through training rather than Inspiration Points, developed advanced spatial techniques, and graduated from the academy with Archive Magic access.
Information Magic LV4	84	Ancient Script Magic merged with his innate Telepathy Magic, granting high-level access to the Ancient Script’s global information network.
S-Class mage; magic power exceeding 50,000	104	Defeated the other S-Class promotion candidates simultaneously through Space, Word, Light, Telepathy, Thought Projection, and Dragon Slayer-derived abilities, becoming Fairy Tail’s youngest S-Class mage at age twelve.
Time Magic LV2; Fairy Sphere acquired	110	Obtained Fairy Sphere and used its time-space principles to rapidly advance Time Magic. He identified Space Magic LV3 and Time Magic LV3 as the minimum requirements for fully casting the super-magic.
Light Magic LV4; Light Laser Eyes	114	Developed light-speed-style flight at a sustainable speed of roughly Mach 10 and, with Information Magic, learned to adjust light’s wavelength and frequency to fire destructive beams from his eyes. His magic power surpassed 70,000.
Curse Arts LV1	146	Acquired through analysis of the demon Lullaby; the art uses emotional energy to amplify magic, though Aibo considered it better suited to his creations than to himself.
Life Magic LV1	160	Developed while examining Deliora’s demonic knowledge and Fairy Law, expanding his work on artificial life.
Form Magic LV4	164	Raised from LV2 with Inspiration Points before the confrontation with Phantom Lord; used to strengthen his physical constitution and upgrade his solar-powered artificial lifeform Phoebe.
Modified God Slayer Magic; Light God Core	174	Created a simulated core beside his Dragon Seed. Its black, multicolored light offered little additional attack power but absorbed ordinary light efficiently for energy recovery and storage.
Devil Slayer Core	174 175	Engineered a core that absorbs emotions and converts them into Curse Power. He subsequently considered converting his God Core into a Demon Seed rather than maintaining three separate cores.

Background / History

Aibo is a transmigrator whose memories of a previous twenty-year life resurfaced after the village chief who had raised him died before his eyes. Shortly afterward, a Dark Magic Cult captured and beat him; his dormant Telepathy Magic awakened in the crisis, allowing him to call Gildarts for help across a distance exceeding ten thousand meters. Gildarts annihilated the cultists and brought Aibo to Fairy Tail. 1

The new magic initially left Aibo nearly incapacitated. He could receive the thoughts of people around him without shutting the ability off, causing constant headaches and his vacant, dazed appearance. Makarov nevertheless accepted him as Fairy Tail’s newest member and had Airo apply his guild mark. 1 2

Aibo initially set five goals for his new life: earn money, become stronger, research his system-like “cheat,” have fun, and avenge the village chief by destroying the Oblique Angle Cult. The Magic Council’s destruction of several Dark Magic Cults prevented him from carrying out that revenge himself. 4 5

After adapting to the guild, he learned to read and write under Cana’s guidance, worked as a guild waiter, and rapidly accumulated a broad foundation in magic. His need for silence and concentration eventually led him to leave the dormitory and construct a home near the riverbank using Earth, Wood, and Shaping Magic. 5 12 13

Following his academy graduation, Aibo gained access to the Ancient Script’s global information network and began pursuing projects beyond individual magical research. He persuaded Fairy Tail’s chairman to support plans to develop Magnolia into a metropolis, establish businesses and industrial facilities, and improve guild members’ employment, welfare, and technological resources. 84 96

During the Beast King incident, Aibo and Lisanna were displaced to an alternate world through the Kingdom Research Institute’s Hyperdimensional Magic—Anima. After studying the foreign world’s magic and retrieving Anima’s spell model, Aibo returned to Earth-land, while providing Lisanna with tools to communicate with Mira and transmit knowledge from Edolas. 87 90

Aibo later helped investigate Duke Everlue, turning a request to destroy the book DAYBREAK into an effort to gather testimony against the duke. On Galuna Island, he took command of Lyon’s group opposing Deliora under the title “Love Emperor,” distributing communication terminals and organizing the group’s members. His subsequent study of Deliora, demons, and artificial life led to Life Magic and new Slayer-type core technologies. 131 148 160 174

During Fairy Tail’s conflict with Phantom Lord, Aibo developed the artificial lifeform Phoebe as a weapon, helped coordinate the guild’s response, and earned enough trust that members followed his directions readily after the guild war. 163 164 168

Appearance

Aibo is a light cherry-pink-haired boy with delicate features and an unusually adorable appearance. His initial short haircut and unfocused eyes made him appear harmless or absent-minded while his uncontrolled Telepathy Magic overwhelmed him. 1

• Hair: Light cherry-pink; normally short, but becomes long and tied in a high ponytail when using his older Transformation Magic form. 1 35
• Build: Initially small and physically frail for his magic reserves; Body Tempering Magic later makes him taller, sturdier, and notably more handsome. 41 60 78
• Transformed appearance: Can take the form of a handsome fourteen- to fifteen-year-old with a stronger build and a mischievous smile. 35
• Academy disguise: His Thought Projection, “Hannah Aibo,” uses softened features and a slimmer figure to pass as a girl. 65 66
• Later physique: By age fourteen, Body Tempering Magic had made him nearly as tall as Natsu and Gray, with stamina nearing 10,000 and strength around 8,000, though his youthful face still made him appear younger than them. 116

Personality

Aibo is intelligent, pragmatic, and intensely curious about magic. He treats every new spell, ordinary skill, and magical phenomenon as something to be tested, quantified, and improved. He quickly recognized that Inspiration Points arise from positive emotional feedback, but still prefers learning and training naturally when possible rather than relying entirely on forced upgrades. 3 7 8 12

He is disciplined when pursuing a goal, maintaining a demanding routine of practice, guild work, research, writing, and meditation. His long-term focus is generally strategic: he stockpiles Inspiration Points, specializes in Space Magic, develops his body to support his mana reserves, and builds systems that let him train or provide support efficiently. 14 24 60

Despite his polite and childlike outward behavior, Aibo can be calculating and mischievous. He deliberately played up his vulnerable appearance to gain Gray and Cana’s affection, privately judges others through their thoughts, and has a tendency to view relationships as something that can be cultivated. 4 35 77

Aibo is also protective of those he considers his family. He created emergency summoning cards for Cana, Levy, and Erza, left a teleportation mark on Mira, helped Leo survive despite Virgo’s objections, and chose to aid Lisanna in returning from another world. 32 80 84 87

After becoming an S-Class mage, Aibo deliberately cultivated the public image of an innocent, easily embarrassed boy around the women close to him. He uses their teasing both to maintain that persona and to generate Inspiration Points, while privately retaining full awareness of their attempts to manipulate him. 105 106

Though his moral boundaries can be flexible and he readily proposes extreme solutions to problems such as Duke Everlue’s abuses, Aibo is deeply motivated by gratitude toward Gildarts and Fairy Tail. His plans to industrialize Magnolia and improve guild benefits stem from his desire to repay the guild for taking him in. 96 128

His ruthlessness extends to coercing Ultear during an interrogation, while his treatment of Kaby Melon shows a more compassionate side: after uncovering Kaby’s true reason for commissioning the DAYBREAK job, Aibo declined to take excessive payment from him and sought evidence against Everlue. 120 131

Abilities & Skills

System and Inspiration Points

Aibo possesses a private system that records magic, mundane skills, physical attributes, and experience progress. Skills gain experience through what he considers a proper, successful use; Inspiration Points can forcibly raise skills or unlock abilities. 3 7 12

• Positive feelings—particularly excitement, joy, and affection—generate Inspiration Points. 6 7
• Forced advancement can leave a spell powerful but unstable or difficult to control. 8
• The system recognizes self-created abilities, including Body Tempering Magic. 45
• He can record non-magical disciplines such as Writing, Cooking, Drawing, and martial techniques as skills. 12 50
• Aibo can also acquire Inspiration Points through combat, including physical battles against magical beasts. 51 52
• He later exploited his innocent public persona and the attention it drew from his older sisters as a further source of Inspiration Points. 106

Telepathy and Information Magic

Aibo’s innate Telepathy Magic is his highest-level natural ability. It enables thought-based communication, thought-reading, and later, information interference. 1 3 20

• Sent a distress signal over ten thousand meters during his initial abduction. 1
• Initially received the thoughts of everyone within almost one hundred meters and could not turn the effect off. 1
• Can suppress weaker Telepathy Magic, intercept transmitted information, and insert false information into another user’s spell. 20
• Improved body control eventually allowed him to stop listening when he wished. 60
• Ancient Script Magic later merged with Telepathy Magic into Information Magic LV4. 84
• Aibo determined that the thoughts he reads are magical interpretations of electromagnetic brainwave signals. He is researching applications involving emitted electromagnetic waves and the combination of Information and Light Magic. 96
• He is attempting to develop an appraisal-style spell capable of quantifying others’ physical and magical attributes through Information Magic and the Super Ancient Grimoire’s knowledge base. 129
• He uses Information Magic in a magical “black box” that analyzes spell structures. When it could not fully interpret Lullaby’s magic, Aibo questioned the demon through telepathy. 141

Space Magic and Teleportation

Space Magic is Aibo’s most compatible magical discipline and the basis for his travel, rescue, and remote-support techniques. 14

• Teleports himself over short distances and eventually develops advanced spatial techniques and resistance to spatial fluctuations. 16 82
• Aibo’s Mark / Flying Thunder God Space-Time Flash, First Formula Seal functions as a spatial coordinate; an activated mark lets him teleport to its bearer from nearly fifty kilometers away. 18
• Can make large objects disappear and reappear through spatial manipulation, including Elfman’s house. 38
• Uses globally shared Ancient Script coordinates to teleport anywhere on the planet. 84
• Created an Instant Teleport Card for Gildarts before his dangerous mission. 80
• At Space Magic LV4, he can control the space around a battlefield, exile attacks into another dimension, and coordinate combat through instantaneous movement. 82 104
• He uses tiny spatial portals for precise utility applications as well as long-range movement. 106
• During the Everlue investigation, he cut the duke’s study out of its surroundings with spatial magic while searching for DAYBREAK. 131

Thought Projection

Aibo can create a synchronized thought-body resembling a clone without splitting his consciousness. 49

• A Thought Projection shares information with the original body rather than becoming an independent mind. 49
• By assigning attention and magic power to the projection, Aibo can dull the original body’s pain and train or research in two places at once. 49
• He sent a projection with most of his magic power to the Magic Academy as “Hannah Aibo.” 65 66
• The academy projection was restricted to Word Magic and Ice Magic to preserve his cover identity. 65
• After graduation, Aibo regularly divides research between his main body and Thought Projection, allowing simultaneous work on separate magical fields. 96
• In combat, he can use a Thought Projection as a teleporting close-range attacker while his real body remains at a favorable distance. 104

Enchant and Word Magic

Aibo’s Enchant Magic can attach properties from magic he understands to people or objects. His Word Magic expands these effects into complex magical programs. 43 44

• Applies elemental attributes such as light, zero gravity, space, and healing. 42 43
• Can turn cards into spatial storage, lock a target inside an enchanted card, or create a self-writing pen by enchanting it with his soul. 43
• Developed Word Enchantment: Fully Autonomous Body-Tempering System, a cycle that damages and heals targeted muscle tissue to train the body automatically. 44
• Enchant Magic enhances the recipient’s power rather than directly multiplying Aibo’s own strength. 43
• His experiments can be excessive; Mira was repeatedly pushed to exhaustion while he tested enchantments. 43
• At Word Magic LV4, Aibo can rapidly construct powerful word-based spells and interfere with or rewrite opposing magic. 78 104
• He inscribed runes on Ultear that heightened her sensitivity to pain during an interrogation. 120

Body Tempering and Martial Arts

Aibo developed Body Tempering Magic to solve the mismatch between his growing mana reserves and weak physique. 41 45

• Raises base physical attributes and improves magic control as his body grows stronger. 45 60
• Uses magical stimulation, sparring, combat, and recovery magic to improve stamina, energy, and physical resilience. 52 60
• Can record martial arts and weapon techniques as system skills. 50
• Fought a giant dinosaur with a spear rather than relying on magic, discovering that battle also earns Inspiration Points. 51
• At LV4, the magic affects his entire body, eliminating minor ailments and greatly improving his vitality. 78
• Continued body tempering transformed his physique to the point that, by age fourteen, his raw physical capability approached that of the guild’s older combatants. 116
• He later raised Form Magic to LV4 to further strengthen his constitution; at that point, his recorded Mind, Stamina, and Magic Power were 12,431, 10,201, and 93,624 respectively. 164

Light Magic and Light Make

Aibo uses Light Magic for construction, defense, illusion, and large-scale combat. 38 74

• Created a Light Prison whose controlled light, shadow, and color formed a one-way barrier around hostile villagers. 38
• Can change light constructs’ attributes through Word Enchantment, such as making a light staff take on metallic properties. 74
• Escaped Gray’s Ice Prison by transforming into light. 74
• Formed a giant humanoid of light over ten meters tall and defeated both Natsu and Gray in a three-way battle. 74 75
• Can fire sustained light beams while simultaneously directing a Thought Projection and other spells in combat. 104
• He is reconstructing Light Magic alongside Information Magic in hopes of overcoming its limited offensive wavelength variation and developing a Heat Ray-style spell. 96
• Upon reaching Light Magic LV4, he achieved flight at approximately Mach 10 through partial elementalization, though his physical and neural limits prevented him from safely flying much faster. 114
• He developed Light Laser Eyes by using Information Magic-assisted magic circles to alter light’s wavelength and frequency. The resulting beams can slice through a small mountain peak. 114
• He used his eye beams to disable resistance and cut through Duke Everlue’s castle during the DAYBREAK investigation. 131

Dragon Power

Aibo possesses a Dragon Seed-derived power associated with light and space, though he has not developed conventional Dragon Slayer Magic as Natsu has. 42 74

• His Dragon Seed allows him to devour light and space elements, but the scarcity of such elements has kept his Dragon power at LV1. 74
• During the S-Class promotion test, he swallowed Mistgun’s light-like Divine Punishment beam, demonstrating the practical combat value of his elemental consumption. 104

Slayer Cores and Curse Arts

Aibo later investigated Slayer-type magic as a structure built around a conceptual element, specially configured mana, and a core that stores the element and converts mana. He concluded that a physical seed is not strictly necessary if its core function can be reproduced. 174

• Modified God Slayer Magic: After two failed attempts, Aibo formed a simulated Light God Core beside his Dragon Seed. It produces multicolored black light and improves his absorption of ordinary light, chiefly benefiting energy replenishment rather than attack power. 174
• Second-Generation God Slayer Mage Modification Technology: He placed a God Core inside a Magic Crystal and implanted it into Phoebe, improving her ability to absorb sunlight. He considered the method potentially suitable for producing more God Slayer mages, but had no immediate plan to mass-produce them. 174
• Curse Arts: Analysis of Lullaby gave him a skill for using emotion-derived energy to amplify magic. He identified Emotion Power as a form of magic power produced when emotions fuse with magical particles. 146
• Devil Slayer Core: He created a core able to absorb emotions efficiently and convert them into Curse Power, recognizing Devil Slayer Magic as closely related to Modified God Slayer Magic and Curse Arts. 174
• He applied an upgraded Devil Slayer core technique to Mira, enabling her to use non-elemental Devil Slayer Magic and emotion-derived power alongside her demonic transformation. 175

Celestial Spirit and Summoning Magic

Aibo researches Celestial Spirit Magic as a framework for creating more versatile summoning techniques. 24 32

• Contracted the Canis Minor spirit, a pink puppy he can maintain as a pet with less mana than his natural recovery rate. 24
• Summons Virgo, whose Earth Magic and combat ability scale with Aibo’s available magic power. 30
• Created Summoning Cards that teleport a thought-form carrying part of his mana and abilities to a cardholder. 32
• A summoned thought-form is synchronized with Aibo and can be used for remote support; fatal damage to it does not injure his original body. 32
• Can use Celestial Spirit Requip / Star Dress to temporarily raise the level of magic associated with a spirit. 59
• Provided Leo with stellar magic power so he could remain in the human world. 80

Archive and Ancient Script Magic

After graduating from the Magic Academy, Aibo acquired Archive Magic and access to the Super Ancient Grimoire. 82

• Understands the Ancient Script as a global cloud database with access levels determined by Information Magic. 84
• Holds unusually high permissions, allowing him to access worldwide terrain, weather, disasters, and magical information. 84
• Learned that the Magic Council’s Etherion and Face weapons are operated through the Ancient Script. 84
• Keeps the true extent of his access secret from the Magic Council. 84
• Ancient Script can compress and transmit information into another person’s mind, enabling rapid magical instruction at the risk of mana drain and potential brain damage. 84
• His Level 4 authorization can influence whether Etherion is launched when a Magic Council vote requires high-level Ancient Script approval. 122

Time Magic and Fairy Sphere

Aibo researches Time Magic through the Memories of Time book and the time-space principles embodied in Fairy Tail’s super-magics. 61 64 110

• His early attempts to gain experience in Time Magic through Memories of Time proved ineffective. 64
• He later obtained Fairy Sphere, an absolute defense that freezes an area’s time and space by concealing it within a space-time rift. 110
• Aibo’s study of Fairy Sphere rapidly advanced his Time Magic to LV2, though he concluded that properly casting it requires at least Space Magic LV3 and Time Magic LV3. 110
• He theorized that Iced Shell transforms its caster completely into ice rather than necessarily killing them immediately, leaving open a difficult, time-sensitive possibility of restoration. 77

Magical Engineering and Artificial Life

Aibo applies Archive, Word, Celestial Spirit, and magic-tool knowledge to the development of magical technology and artificial life. 90 96

• He created low-consumption magic gloves, boots, a defensive belt, and a Magic Communication Terminal for Lisanna, enabling her to contact Earth-land from the alternate world when a signal is available. 90
• He is working with old Mistgun on methods to mass-produce Magic Communication Terminals as part of Fairy Tail’s industrial development. 96
• His Thought Projection conducts magical-life creation experiments, resulting in Guga, a rudimentary penguin-costumed artificial lifeform with thought but no functional combat or speech systems. 97 98
• Fairy Tail’s research department developed a prototype flying magic car equipped with Gravity and Wind Magic arrays, which Ailu is capable of driving. 130
• He made Crimson Armor for Erza from Mithril Alloy, incorporating defense, mobility, mana recovery, and an information system that filters battlefield data onto her retina. The armor compresses into a belt for transport. 141
• He developed the Seven Sins Guga, artificial beings whose abilities are drawn from powers he possesses. Their construction gave him further insight into selecting focused abilities for artificial life. 160
• He created Phoebe / Fibi Chubi, a solar-powered artificial lifeform whose Form Magic lets her absorb light and alter her mass and size. He later implanted a Light God Core-containing crystal to improve her solar-energy absorption. 164 174
• While studying demonic creation, he found that an artificial being’s abilities must be abilities its creator possesses; his comparison of Deliora’s knowledge with Fairy Law contributed to his acquisition of Life Magic. 160

Equipment / Weapons / Items

• Requip doll — Anchor for his early Requip Magic; allowed clothing changes within a five-kilometer range. 7
• Aibo’s Mark — Spatial-coordinate seal placed on allies, including Cana and Mira, for emergency teleportation. 18 84
• Summoning Cards — Cards given to Cana, Levy, and Erza that summon Aibo’s thought-form for support. 32
• Virgo’s Golden Key — Celestial Spirit key used to summon Virgo. 29 30
• Dragon Seed — Mysterious reward that enabled his ability to devour light and space elements. 45 46
• Super Ancient Grimoire — Divine artifact to which he received authorization through Archive Magic. 82
• Memories of Time — Book he studied in an attempt to advance Time Magic and understand time-travel magic. 61 64

• Magical analysis “black box” — Device that examines magical structures through Information Magic; Aibo used it to study Lullaby. 141
• Crimson Armor — Mithril Alloy armor Aibo built for Erza to improve her protection, mobility, mana recovery, and battlefield awareness; stored in a transformable belt. 141
• God Core crystal — Magic Crystal containing a simulated Light God Core, implanted into Phoebe as an enhancement. 174

Relationships

• Gildarts Clive — Savior, first magical teacher, and the Fairy Tail member who brought Aibo into the guild after rescuing him from the cultists. He taught Aibo Meditation and Crush Magic. Aibo considers his rescue an immense debt that he intends to repay through his service to Fairy Tail. 1 3 96
• Makarov Dreyar — Fairy Tail guild master and guardian figure. He welcomed Aibo into the guild, advised him on his magical development, arranged his academy enrollment, and later worked with him on Fairy Tail’s expansion and welfare plans. 2 58 64 110 |
• Cana Alberona — Closest sister-like companion. She taught him literacy, became highly protective of him, accompanied him on jobs and magical-beast hunts, and received one of his Summoning Cards. She also knows how to exploit his apparent weakness around attractive women. After moving into his home, her closeness left Aibo increasingly conscious of his attraction to her. 5 32 35 100 104 105 |
• Gray Fullbuster — Early friend and occasional instructor. Gray developed a protective, brotherly attachment to Aibo, but Aibo later surpassed him in their three-way duel and again overwhelmed him in the S-Class promotion test. 4 6 74 75 104 |
• Airo — Fairy Tail hostess who applied Aibo’s guild mark and treated him with maternal affection. 2 3 |
• Erza Scarlet — Training partner and protective older-sister figure. Aibo supports her weapon magic, created body-tempering enchantments for her, and gave her a Summoning Card. He later made her Crimson Armor to improve her chances against Jellal. 18 32 44 141 |
• Levy McGarden — Cana’s friend and one of Aibo’s closest companions. She helped him pursue further magic study and received a Summoning Card. She later became an executive within the staff group formed around Aibo’s enterprises. Her feelings for Aibo developed into romantic rivalry with Juvia, with whom she agreed to compete fairly for his affection. 8 32 128 185 |
• Mirajane Strauss — Friend and frequent test subject for Enchant Magic. Aibo later left her a spatial mark and immediately answered it when she was endangered by Elfman’s loss of control. He subsequently gave her an upgraded Devil Slayer core technique, greatly strengthening her demonic abilities. 43 84 175 |
• Lisanna Strauss — Aibo’s friend and fellow victim of Anima’s alternate-world displacement. Though they briefly clashed over her wish to remain with the alternate world’s Strauss siblings, Aibo ultimately prepared magic tools and a communication terminal for her before returning to Earth-land. 87 89 90 |
• Virgo — Contracted Zodiac Celestial Spirit and research partner. Virgo remains at Aibo’s side because of his abundant magic power and assists his Celestial Spirit studies. 30 31 |
• Ailu — A pink-and-white striped talking cat hatched from Aibo’s egg. Aibo acts as her “Boss,” teaches her to speak, and brings her on adventures. She later pilots Fairy Tail’s prototype flying magic car. 49 50 130 |
• Ultear Milkovich — Academy roommate of Aibo’s “Hannah” projection. Their conversations are unusually candid because Aibo’s Telepathy Magic exposes Ultear’s thoughts and intentions. Aibo later captured and interrogated her before proposing cooperation; after receiving Ur’s memories, Ultear chose to commit herself to him and gather intelligence on Oración Seis. 66 77 120 157 |
• Leo / Loke — Banished Celestial Spirit whom Aibo aids with stellar magic power; Leo subsequently joins Fairy Tail and becomes part of Aibo’s Celestial Spirit research. 80 |
• Juvia Lockser — An admirer who considers Aibo her prince and investigated the women around him as potential rivals. She later alternates with Levy in protecting Aibo from Cana and Mira’s teasing. Her rivalry with Levy becomes more openly romantic, though the two agree to a truce and fair competition. 76 106 185 |
• Lucy Heartfilia — Ally in the alternate world, where she identified a different Aibo Heartfilia as her younger brother and agreed to help Aibo conceal his situation. After their reconciliation, she accompanied Aibo on his investigation of Duke Everlue and accepted a magic necklace from him. Aibo continues to tease her, while Lucy considers their friendship relatively new and worries about misjudging his boundaries. 87 90 128 130 187 |
• Siegrain — Former Magic Academy classmate who became a Ten Wizard Saint and Magic Council member. Aibo views his rapid rise competitively but chooses not to interfere with his affairs. 116 |
• Kaby Melon — Client who initially asked Aibo to destroy DAYBREAK. After uncovering Kaby’s desire to avenge his father, Aibo declined excessive payment and asked him to gather other victims to testify against Duke Everlue. 131 |
• Lyon — Former leader of the group opposing Deliora. After recognizing Aibo’s strength and accepting his promise that Lyon could attack Deliora first, Lyon yielded leadership to him on Galuna Island. 148 |
• Sherry Blendy — Member of Lyon’s group whom Aibo won over through persuasion and shared opposition to Deliora. She grew attracted to him as he assumed leadership. 148 150 |
• Lullaby — Demon Aibo confined in his analysis device and questioned telepathically. It disclosed information about Tartaros, Zeref’s Bookshelf, and the purpose of Zeref’s demons. 141 |
