History

Ais was discovered asleep in an abandoned ruin, enclosed within a weakening wind barrier that could otherwise have preserved her slumber for years. Guided by Aria's Blessing of Wind, Ming Ge sent Mavis to locate her and dispel the barrier. 121 126

After awakening, Ais witnessed an illusion of the Black Dragon's defeat and her parents' return to the heavens. With her revenge goal gone, she was left without direction until Ming Ge urged her to repay his kindness and find a new purpose. She promised to become his strength, and the two formally introduced themselves. 127 128

Ais entered Ming Ge's household, where she gradually accepted Meitellia and Alfia. Her trust in Ming Ge was immediate and intense; after losing her parents, she sought safety by sleeping beside him rather than alone. 129 147

Although she wished to become an adventurer immediately, Ming Ge delayed her Falna so she could develop hidden ability parameters by training to her natural limit first. He began teaching her swordsmanship with a custom wind-conductive sword, emphasizing fundamental movements before advanced techniques. 145 148

Ming Ge used Regulation Magic to optimize Ais's physical condition and accelerate her growth. She also trained through meditation and the Spiritual Training Method, eventually becoming skilled enough to teach swordsmanship and meditation to Elize. 149 175

After reaching her limit, Ais became the first new Astraea Familia member permitted to receive Falna under Ming Ge's training system. She then entered the Dungeon for practical combat, where she fought through monster hordes and defeated a dragon-type monster several levels above her. 197 199 200

Appearance

Ais is a blonde little girl, seven years old when Ming Ge begins her formal swordsmanship training. 126 148

• Blonde hair. 126
• Initially found sleeping peacefully within a wind barrier. 126
• Uses a double-edged, sharp-tipped training sword designed for wind-attribute conductivity. 148

Personality

Ais is persistent, earnest, and notably trusting toward Ming Ge. She tends to take matters literally and can appear airheaded, but once she decides on a responsibility—such as becoming Belsia's older sister—she remains steadfast. 129 198

Her hatred of the Black Dragon shaped Avenger, even after the dragon's death. Rather than deny that feeling, she accepts Ming Ge's guidance to judge for herself who truly deserves to be called a monster, regardless of appearance. 199 200

Despite her fear when surrounded by Dungeon monsters, Ais can regain resolve through reassurance and continue fighting. She relies on Ming Ge as her hero and protector. 201
