Mysterious Heroine X Alter

She appears as a slender teenage girl with short, pale blue hair and piercing amber eyes, typically dressed in a modified school uniform featuring a navy blazer and a long, frayed red scarf. She often wears spectacles and is seen carrying a high-tech, double-bladed sword that emits a sinister red glow. Her expression is usually calm and somewhat detached, giving her a quiet but intense presence.

Reclusive, gluttonous, diligent, deadpan, and calm.

Anti-Anti-Saber Weapon

Created by the villainous 'Dark Round' organization in the Servant Universe, she is a clone of Mysterious Heroine X designed to be the ultimate Anti-Anti-Saber weapon. Though she is a 'Sith Lord' parody fueled by the Alter Reactor, she is surprisingly lazy and prefers spending her time eating sweets or listening to music over galactic conquest. She operates as a Berserker-class Servant, balancing her destructive dark powers with a mundane craving for expensive Japanese treats.
