Fiona Frost

A long fringe conceals most of the right half of Fiona's face, with the rest of her bobbed hair drawn back over her left ear. The anime renders that hair white against dark gray eyes; the manga colors her lavender with purple eyes instead. Pale skin, light lashes, a slim build, and a 172 cm frame round out a look Yor plainly calls beautiful, and admirers follow her accordingly. Her precise age has never been stated, though she reads as younger than Loid, and her default expression gives away nothing at all.

Visiting the Forger apartment, she arrives in a pea coat of dark blue over a purple turtleneck sweater, leather pants, brown gloves, and heeled ankle boots, her black stud earrings shaped after the WISE insignia. Nursing shifts at Berlint General Hospital call for different dress: a striped gray vest layered over a white shirt and navy sweater, a knee-length black skirt, dark tights, and heels.

Twilight once instructed her to bury her feelings, and she obeyed so completely that nobody has seen her smile since. Beneath the blank mask runs an obsessive inner monologue devoted to him. She loves the man underneath every alias he wears, judges herself the one candidate truly fit to become his wife, and has pitched swapping herself in for Yor on Operation Strix to Loid and to their handler Sylvia Sherwood alike. She understands that forcing the issue would draw suspicion onto the mission, so desire and duty grind against each other constantly, clouding a judgment that is otherwise razor sharp.

Most WISE colleagues read her coldness as ruthless careerism, though what actually drives her is the need to prove her worth to her former mentor. That perfectionism turns self-punishing; injured hands at the Campbelldon tournament did not stop her from playing, and both Twilight and Sylvia have scolded her for treating pain as a line item. Extreme pressure cracks the facade. She batters the Bolic brothers for humiliating Loid, weeps alone after Yor overwhelms her on the tennis court, and erupts into open fury the moment Winston Wheeler threatens Twilight's life. Any direct exposure of her hidden feelings flusters her badly, whether it is Sylvia revealing she has seen through her or Loid briefly weighing her "Neo Strix" proposal. She distrusts people readily and will manipulate them when a mission demands it, once arranging an SSS ambush to squeeze a counterfeiter into cooperating, yet she still builds workable partnerships with allies like Franky Franklin.

Training under Twilight made her formidable. She once wiped out an entire enemy cell alone, throws SSS officers with clean technique, and can hoist a grown man overhead before slamming him down. A mountain regimen, undertaken after her tennis defeat, left her hauling roped log piles with a bear perched on top. Rage transforms her entirely: against Wheeler she moves too fast for a veteran spy to track, ruins both of his arms, and knocks him airborne, though each limb she swings shatters under her own force and one missed punch pops her arm from its socket. Adrenaline carries her through the damage until the fight ends.

Her agility shows in acrobatic dodges through crossfiring rubber bullets during an underground tennis bout, and in slipping a live round while pinning the shooter's hand with a thrown knife. Years spent watching Twilight sharpened her eyesight to a reported 20/4. She handles a personal sidearm plus mission loadouts of rifles and grenades, reads scenes like a trained investigator, and maintains a poker face so airtight that only Anya's telepathy and Sylvia's intuition penetrate it. Everything circles back to Twilight: the chance to impress him elevates her performance, and a threat to him removes her limits altogether.
