Description
Felix Argyle, alias Ferris, is a cat-eared demi-human scion of the noble House Argyle, renowned for water magic prowess. Locked away at birth by parents fearing noble society’s scorn, he was rescued at nine by Crusch Karsten, who adopted him into her house. He evolved into her devoted knight and attendant, pledging unwavering loyalty to her cause.

A prodigious water mage, Felix earned the epithet “The Blue” as Lugunica’s youngest master healer. His magic mends grave wounds—even reattaching limbs—yet falters against supernatural curses and death itself. Secretly, he wields the forbidden “Sacrament of the Immortal King,” gleaned from ancestral scrolls to briefly reanimate corpses.

Felix embraces a feminine guise tied to a vow with Crusch and the deceased Prince Fourier. Despite this affectation, he asserts his male identity, peppering speech with third-person quirks, playful teases, and feline-inflected “nyan” suffixes. His allegiance to Crusch overrides all, manifesting in ruthless tactics like torture or assassination when safeguarding her interests—a zeal clashing with Subaru Natsuki, whose parallel devotion to Emilia mirrors Felix’s own extremes.

Childhood trauma forged a pragmatist disdainful of fragility and self-neglect. Though he exudes mischievous cheer, years of healing work instilled a stark grasp of mortality. Alternate tales unveil a steely persona when Crusch is imperiled, exposing his brittle psyche’s reliance on her presence.

Enhanced demi-human senses, notably acute hearing, offset his modest physicality. Eschewing brute force, Felix manipulates bodily fluids or immobilizes foes through tactical water spells. He serves Crusch’s campaigns as a strategist and medic, prioritizing logistics and recovery over frontline combat.

His lineage harbors demi-human ancestry unbeknownst to his human parents, complicating his bond with House Argyle. Crusch’s intervention salvaged him from isolation’s scars, anchoring his fractured identity. Across chronicles, his journey navigates loyalty’s paradoxes, selfhood, and the ethical shadows of protective power—all tethered to the woman who gave his existence meaning.
