Ariane Glenys Maple, later Ariane Glenys Lalatoya, is a dark elf warrior from Maple Village in the Great Canadian Forest. Her father, Dylan Tahg Lalatoya, is an elder of Lalatoya Village, and her mother, Glenys Alna Lalatoya, ranks among the elves' most formidable swordsmen. This heritage fuels her pride and dedication as a soldier serving her people.

She bears distinctive dark elf traits: light purple skin, golden eyes, and waist-length snow-white hair usually secured in a ponytail. Her pointed ears are shorter than typical for elves, and her youthful appearance belies an age exceeding fifty years. Her striking figure occasionally hinders stealth. She typically wears maroon corset-style leather armor, a matching skirt, stockings, a gray cloak, and wields a silver sword.

Ariane fiercely dedicates herself to liberating enslaved elves, tempered by a short temper and impulsiveness. Initial distrust of humans, stemming from witnessing treaty violations and enslavement orchestrated by figures like Rhoden's second prince, softens after meeting Arc. However, she permits lethal force against slavers like Marquis Tryton du Diento. She displays deep loyalty to companions, reacting intensely to insults against them, and exhibits a tsundere demeanor—masking softer emotions with bluntness, particularly concerning Arc. Her low alcohol tolerance leads to uninhibited behavior.

Her journey intensifies confronting slavers holding elf children near Diento. Facing defeat due to hostages used as shields, she nearly surrenders before Arc intervenes. Ponta's presence mitigates her suspicion of Arc, and witnessing his magic dismantle slave collars builds trust. She subsequently hires him for missions, including infiltrating Diento's slave warehouse and assassinating Marquis Tryton. After Arc reveals his skeletal form, Ariane discerns he is cursed, not undead, and invites him to Lalatoya Village. Her parents welcome him, and the elders sanction continued anti-slavery operations while avoiding open war.

Her perspective on humans evolves through encounters with Carcy, a human aiding elves, and Traesa, an elf married to a human lord. Ariane's combat abilities blend swordsmanship with spirit magic: earth spells to engulf targets, fire magic to engulf her blade, and wind manipulation. Arc gifts her two swords—the Lion King's Sword and later an unnamed blade forged from dragon lord scales and decayed wood from the Tree King—enhancing her combat efficacy.

Her relationship with Arc evolves from pragmatic alliance to profound mutual reliance. She positions herself as his supervisor to curb his accidental destructiveness, yet grows concerned for his well-being during curses or homesickness. Romantic tension surfaces through jealousy when other women approach him and embarrassment when others perceive them as a couple. Their dynamic includes cooperative battles, like assisting Princess Yuriarna against political conspiracies, and lighthearted incidents like mutual embarrassment after bathing mishaps.

Her partnership extends to Chiyome, a Jinshin clan ninja rescuing enslaved beast people. They share camaraderie through ear and tail appreciation, efficiently coordinating against threats like the Holy Hilk Kingdom's forces. Family interactions reveal her sister Eevin's protective skepticism toward Arc and parental amusement at Ariane's growing affections.

Ariane persists through investigations exposing conspiracies involving the Holy East Revlon Empire and the Holy Hilk Church, demonstrating adaptability in trusting former adversaries and persistence against institutionalized oppression while navigating personal growth and unspoken feelings.
