Background

Ais is the daughter of Albert the Hero, the last hero, and Aria the Great Fairy. After appearing in the modern era as a seven-year-old girl, she was taken in by the Loki Familia. How she survived for a thousand years and arrived in the present remains unknown. Her origins are known within the Familia only to Loki, Finn, Riveria, and Gareth. 715 754

Her overriding purpose is revenge: against the One-Eyed Black Dragon that took her parents and against monsters as a whole. This hatred drives her relentless pursuit of strength and later manifests as her dangerous Vengeful Princess Skill. 715 792

Ais became a First Class Adventurer at exceptional speed, reaching Lv.2 within one year and setting the world's fastest known level-up record at the time. By Lv.5, however, her growth had slowed enough to leave her anxious and dissatisfied despite her outstanding Ability Values. 31 754

Appearance

Ais is a golden-haired, golden-eyed female swordsman whose waist-length hair and cool bearing give her an almost fairy-like presence. Her beauty is widely remarked upon in Orario, even when she returns from the Dungeon covered in dirt and blood. 31 637

• Long, smooth golden hair.
• Golden eyes.
• Usually carries a silver Sabre.
• Maintains an expressionless, doll-like demeanor in public. 15 31 637

Personality

Ais is quiet, direct, and emotionally restrained, often communicating in only a few words. Beneath that detached exterior, she is naturally naive, sensitive, and more emotionally fragile than most people realize. 668 715

Her desire for strength can make her reckless. She repeatedly enters dangerous Dungeon areas alone, trains until exhausted, and pursues fights that could earn her the achievements needed to advance. 31 75 77

Despite her fixation on revenge, Ais is deeply attached to her companions. She worries over Lefiya, Tiona, and Tione, trusts Riezel in battle, and ultimately accepts that her past does not make her separate from the Loki Familia. 31 717 737 754

Abilities & Skills

Swordsmanship

Ais is regarded as Orario's strongest female swordsman. Her swordsmanship is the defining basis of her combat ability, allowing her to overwhelm opponents through rapid, precise barrages of slashes. 15 727 728

• Possesses the Swordsman Development Ability, which improves her Ability Values while wielding a sword. 31 36
• Was capable of defeating Frini Jamiller at Lv.5 and held a decisive advantage after reaching Lv.6. 728
• Regularly spars with Riezel to refine her control, techniques, and adaptation to increased strength. 20 638 681

Wind Spirit Sprint

Wind Spirit Sprint is Ais's unique wind enchantment magic. It surrounds her with abnormal wind and dramatically raises her combat power beyond her base level. 20 34

• Allows her Lv.5 strength to contend with high-ranking Lv.6 adventurers and surpass ordinary Lv.6 opponents. 34 53
• Can be activated through the chant, “Tempest.” 77
• Holds exceptional personal importance to Ais; seeing Riezel reproduce the magic made her feel sadness rather than pride. 20
• Combines especially dangerously with Vengeful Princess. 792

Vengeful Princess

Vengeful Princess is a monster-slaying Skill born from Ais's hatred and desire for revenge. It greatly amplifies her attacks against monsters, with stronger hatred producing stronger effects. 792

• Its enhancement becomes extreme against Dragon-type monsters, particularly those related to the One-Eyed Black Dragon's race. 792
• Lets Ais challenge enemies far above her level; against dragons, she may be able to defeat opponents two levels stronger. 792
• Carries severe physical strain and risks causing her to lose reason under the influence of hatred. 792
• Riezel forbade its use without restraint and entrusted her with El'dor's Tear to protect her mind when using it. 792

Rank Ascension

Ais can temporarily reach Lv.7 when affected by Riezel's Treasure Hammer magic. This is an externally granted enhancement rather than a permanent level-up. 677

Equipment / Weapons / Items

• Silver Sabre / Despair Sword — Ais's primary sword. 20 638
• El'dor's Tear — A secret treasure given by Riezel to protect her mind from the influence of Vengeful Princess. 792
• Indestructible weaponry — Her equipment is durable enough that she does not require the routine repairs needed by most Familia members. 74 693

Relationships

• Riezel Brihaut — Her first magic and swordsmanship student, later her training partner and instructor. They support one another's growth, fight with strong coordination, and grow closer after he learns of her origins. 20 638 654 754
• Loki — Her goddess and the head of the Loki Familia. Loki is protective of Ais, though her possessiveness can be unwelcome. 24 677
• Riveria Ljos Alf — A maternal figure who helped raise Ais and intervenes when her training becomes dangerously reckless. 24 672
• Finn Deimne — Loki Familia commander and one of the few people entrusted with Ais's background. 715 754
• Gareth Landrock — Familia leader and another keeper of Ais's secret origins. 715 754
• Lefiya Viridis — A junior Ais protects and inspires. Lefiya's feelings for Ais become publicly apparent during the Familia's banquet. 31 73 717
• Tiona Hiryute and Tione Hiryute — Her closest friends within the Loki Familia; their disappearance during the Knossos conflict weighs heavily on Ais. 753

Story Role / Major Arcs

Training Riezel

Ais teaches Riezel Wind Spirit Sprint and her sword techniques after recognizing that they share the same longing to become stronger. Their repeated spars establish the foundation of their partnership. 20 24 639

Battle with Udaios

On the 37th Floor, Ais refuses Riezel's intervention against the Lv.6 Floor Master Udaios. She faces the monster alone to earn the achievement she needs, while Riezel supports her with reinforcement magic without taking her victory. 77 78 79

Recklessness and Lv.6 Advancement

Pressured by Riezel's rapid growth and her own stalled progress, Ais becomes increasingly reckless in the Dungeon. After reaching Lv.6, she struggles with her new physical capabilities until Riezel helps her adjust through sparring. 40 75 637 638

The 24th Floor and Revis

Ais accompanies Riezel and the Hermes Familia to investigate an abnormal Food Stockpile on the 24th Floor. The encounter with the Jewel Fetuses, the name Aria, and Revis's presence forces buried memories and fears to the surface, causing Ais to isolate herself afterward. 654 656 668

Accepting Her Origins

During the Knossos conflict, Riezel reveals that he knows part of Ais's heritage. He reassures her that neither her Fairy bloodline nor her connection to Albert and Aria changes her place in the Loki Familia; Ais responds by recommitting herself to her companions and duties. 753 754

Continued Growth

Following the expedition to the 59th Floor, Ais makes major gains across all five basic Ability Values and resolves to continue growing alongside Riezel in order to defeat the Filthy Fairy. 711

Vengeful Princess

Before a major operation, Riezel confronts Ais about the danger of her monster-slaying Skill. He gives her El'dor's Tear as protection, trusting her to use her power responsibly rather than suppressing her desire to protect her comrades. 792
