Luna Heela, known as Luna Healer, is a half-elf cleric revered as a saintly church figure. Her striking silvery-pink hair cascades to her waist, framing pink eyes and elven ears, while her tailored nun-like attire emphasizes her silhouette. Twin magic guns rest in her waist holsters, tools for distant combat support.

Renowned for healing and curse-breaking talents, Luna once paid for these powers with her lifespan—a terror rooted in her mother’s premature demise. This dread faded when Noir Stardia altered her ability, trading life force for gold. Beneath her dignified, compassionate exterior lies a fragility: excessive magic triggers her "Fainting Habit," mitigated by Noir’s "Luna Savings" system, which monitors her vitality.

Bound by loyalty and quiet rivalry, Luna shares a deep friendship with Lola Metrose, though both compete for Noir’s affection. Initially viewing him as a junior ally, her respect evolves into romantic longing after he reshapes her destiny. She playfully dangles submissive overtures, retracting them with coy humor. Her subtle contests with Emma Brightness mask mutual respect, each maneuvering for Noir’s notice.

Once a solitary Odin Guild adventurer, Luna now thrives in Noir’s party, prioritizing ally support through skills like "Healing Shot" and "Decurse." Her mercy spans even enemies, exemplified by healing the hostile Ahgalga Burrone. Growth anchors her journey—overcoming hereditary fears, embracing collaboration, and nurturing affection for Noir. Yet quirks linger: fainting spells, earnest yet teasing intimacy, and a resolve to heal even amidst chaos.
