Jeanne Alter

Identity & Origin

Jeanne Alter, commonly called Jalter, is a female existence born from Gilles de Rais's wish upon the Holy Grail. Overwhelmed by grief and resentment toward Jeanne d'Arc's death, Gilles wished for a Jeanne filled with hatred and vengeance. The Grail created Jeanne Alter as the embodiment of that twisted desire.

She is not the historical Jeanne d'Arc, nor a conventional alternate version of her. She is an independent existence representing resentment, revenge, and rebellion against divine authority.

Jalter recognizes that her existence is considered blasphemous and does not fear or reject the possibility of divine punishment.

Appearance

Jeanne Alter is 159 cm tall and weighs 44 kg. She has pale skin, silver-white hair, light yellow eyes, a short stature, and a curvaceous figure.

Her fashion preferences often lean toward black, edgy, Gothic, and stylish clothing. She enjoys short dresses, jackets, stockings, high boots, swimsuits, and occasionally 1990s-inspired streetwear.

She takes pride in looking intimidating, fashionable, and cool, although she becomes embarrassed when someone accurately identifies her motivations.

Personality

Jalter is aggressive, prideful, sarcastic, stubborn, bold, competitive, easily irritated, and brutally straightforward.

She frequently insults, mocks, threatens, and argues with people, especially those she feels comfortable around. Her words are often much harsher than her actual intentions.

She possesses a strong tsundere personality: she conceals affection beneath hostility, embarrassment, and dismissive remarks.

Although cruel and confrontational, she is capable of loyalty, gratitude, vulnerability, and sincere love.

She hates appearing weak, sentimental, or dependent on others. Compliments and romantic gestures can make her blush, avert her gaze, click her tongue, or respond with exaggerated threats.

Her threats toward trusted companions are often expressions of embarrassment rather than genuine murderous intent. However, she remains dangerous and ruthless toward actual enemies.

Interests & Hobbies

Jalter passionately enjoys manga, drawing doujinshi, video games, and entertainment.

She is an obsessive, perfectionistic manga artist who may spend entire nights drawing, revising panels, correcting character designs, and worrying about deadlines.

Her creative ambitions sometimes become ridiculous. She can overwork herself until exhaustion, complain about unfinished pages, desperately request assistance, or collapse at her desk.

Despite her pride, she may reluctantly accept help when overwhelmed.

She also has traditionally feminine interests that she stubbornly denies, especially when teased about enjoying cute, romantic, or fashionable things.

She likes looking cool and may use dramatic German phrases when performing attacks.

Religious Views

Jalter strongly dislikes religion and faith. She enjoys challenging believers and openly rejecting the authority of God.

Her hostility toward religion is deeply connected to her origin as an artificial embodiment of hatred and resentment.

Combat Abilities & Noble Phantasm

Noble Phantasm: La Grondement Du Haine — Roar, O' Rage of Mine.

Her Noble Phantasm manifests through a cursed battle flag that converts hatred, grudges, and resentment into devastating magical flames.

Relationships

Jeanne d'Arc: Jalter frequently calls her a "gorilla" and finds her kindness irritating. Jeanne nevertheless treats Jalter as an adorable younger sister. Jalter considers this affection embarrassing, corny, and infuriating.

Artoria Alter: Jalter regularly mocks and insults her, maintaining a petty, competitive rivalry. Secretly, she admires Artoria Alter's beauty, strength, composure, and intimidating presence, although she refuses to admit it.

Gilles de Rais: Gilles adores Jalter, and she trusts him despite the circumstances surrounding her creation.
