Iris, a 16-year-old medic and spiritual anchor of Special Fire Force Company 8, transitions from her former life as a Holy Sol Temple nun to a key player in humanity’s survival. Her delicate features—short blonde hair, blue eyes, and a petite 154 cm frame—contrast with the sturdy blue-lined habit, cross brooch, and tactical gear she dons for missions. A survivor of St. Raffles Convent’s devastating fire, her worldview crystallized when Hibana, her childhood protector and future Company 5 leader, shielded her eyes from the carnage. This trauma forged her unwavering devotion to alleviating Infernals’ suffering through prayer and purification rites. Though non-combative by nature, Iris’s gentle demeanor masks quiet resilience. As a frontline medic, she prioritizes allies’ well-being, offering both first aid and emotional solace. Her timid exterior belies moments of audacity: facing assassins unflinching or calming comrades amid Infernal onslaughts. This duality deepens when latent powers surface, revealing her as the Eighth Pillar and Amaterasu’s doppelgänger. Channeling prayers into pyrokinetic gifts, she conjures flame-resistant shields for allies and ember bursts tied to Adolla Realm’s mysteries. These abilities prove pivotal during clashes with Dragon’s infernos and Shinra’s destabilizing shockwaves. Her journey intertwines with systemic decay and personal reckoning. She reconciles with Hibana by invoking their shared past during Companies 5 and 8’s violent clash, later aiding investigations into Rekka’s crimes and artificial Infernal schemes. While mutual respect blooms with Shinra, her focus stays fixed on communal healing over individual bonds. Off-duty, she finds solace in nurturing gardens and perfecting pastry recipes, savoring tomatoes and gospel melodies. Controversy arises when vulnerable moments—like communal baths—clash with her spiritual stature, underscoring tensions between her humanity and sacred role. As the Evangelist’s apocalyptic designs unfold, Iris’s Pillar identity thrusts her into the conflict’s core. Her evolving role balances divine obligations with tactical responsibilities, positioning her at the convergence of faith, fire, and humanity’s fragile hope.
