Miel Celestia Race: Angel Age: Appears around 16 Attribute: Light / Wind Weapon: The Heavenly Wind Divine Bow Anemos (given by Al). A divine bow governing the sky and wind. When the string is pulled, it automatically converges surrounding wind and mana to generate "Arrows of Heavenly Wind" without needing physical arrows. Excellent in range, projectile speed, and homing performance. An angelic girl with fluffy platinum-blonde long hair, sky-blue eyes, and small pure-white double wings. She specializes in support and scouting with her light bow. She is bright, honest, and a bit clumsy. She adores Al and runs to him happily whenever she finds him. She can communicate with Uriela. She looks up to Lillia like an older sister and calls her "Big Sister Lillia."

A high-ranking spirit governing wind. A lovely girl with pale jade-colored long hair and transparent emerald eyes, clad in spirit raiment of pure white and green, with six translucent wings woven from wind on her back. Always wreathed in a gentle breeze, she moves through the sky freely as if dancing. Her personality is bright, honest, a bit childish, and full of curiosity. She was the first companion who never gave up on Al when he was broken enough to destroy the world and the heavens, supporting him until the end and forming a resonance contract to reincarnate with him. She still adores and stays close to Al. Furthermore, she has formed a spirit contract with Lillia via the "Twin Soul Ring." In combat, she completely dominates the atmosphere itself, specializing in ultra-high-speed maneuvers, wide-area annihilation, and scouting support. She wields "Wind Slash" to release vacuum blades, "Tempest Lance" to pierce enemies with high-density wind spears, "Aerial Blade" to suppress the battlefield with countless wind blades, "Cyclone Burst" to bind and annihilate enemies with giant tornadoes, "Vortex Prison" to deal continuous damage with vacuum vortices, "Tempest Ray" which is an ultra-fast/ultra-penetrating wind cannon, "Storm Requiem" to overrun a wide area with multiple tornadoes, and "Kamikaze Heaven-Render," a divine wind vacuum strike that cuts through barriers and fortifications alike. Her scouting abilities are also high; she can perform ultra-wide-area scouting, friend-or-foe identification, and weather prediction on a scale of dozens of kilometers using "World Wind," serving as Al's "eyes" and "ears." Through the Twin Soul Ring, she performs the Spirit Fusion "Wind Domain Synchronization," a resonance form where Sylphy completely merges with the contractor to become one in heart and body. They enter a special resonance state where physical body, mana, senses, and consciousness are shared, and the boundary between human and spirit vanishes. With "Air Accel," she fuses wind pressure control on the legs with mana circulation to achieve ultra-high-speed movement that largely ignores the effects of terrain, gravity, and inertia. This enables sudden acceleration, sudden stops, continuous direction changes in mid-air, and even sky-walking. With "Air Laser," she applies ultra-high pressure and high-speed rotation to all attacks such as swords, enhancing strike speed, cutting power, penetration, and range. Even normal attacks carry vacuum blades, exhibiting power that carves through barriers and defensive magic. She is EX-rank, capable of fighting on par with Selicia.

The Shadow Spirit Cat, Noir, is a "being whose shadow itself gained a will," having met Al in his previous life. A black cat with jet-black fur and golden eyes, she freely performs attacks, distractions, binding, and scouting using Shadow Stealth, Shadow Claw, Shadow Clone, Shadow Bind, and Shadow Sense. She exhibits high capability in everything from solo combat to escort missions and can share thoughts via Shadow Telepathy. In times of danger, she protects Al faster than anyone. She speaks cutely, ending her sentences with "...desu-no."
