A single meteor that came to destroy the Servant Festival.
A delegate of the laws of the universe, she eradicates Earth's mankind and the Foreigners who shares the same attributes as herself. A peerlessly ruthless Machine Servant.
It has been said that, when her unexpected true face is revealed, anyone will avert their gaze due to extreme astonishment―――?
To put it simply, Mysterious Heroine X is the protagonist of a comedy-drama.
However, the Servant Universe came to a standstill and the proportion of heroes and villains crumbled due the excessive issue of Extra Classes. When the balance of the universe tilted towards the villains, X renewed her convictions. In more specific terms, the program embarked on a new season. Worried about being unemployed, X got herself a job on the secret society・Galaxy Police and coincidentally caught Rhongomynyad, the oldest artifact in the universe that was lying dormant at its center. Having her talents recognized, she began to play an active role as a space sentinel (Galaxian).
- extract from the 1st part of CG's story -
Upon becoming a Cosmic Sheriff, X thought "this is a good opportunity" and changed her name・family register to XX.
By becoming a new person, she defaulted all debts incurred so far and established the Division 0 of Special Investigations, which cracks down on invaders from outer space - the Foreigners. The birth of the Evil Deity Hunter, XX.
Her instinct as a Saber Hunter became dim, while her instinct as a Foreigner Hunter came to prominence. That being said, it is not like she quit her Saber elimination movement, so the special effectiveness against Sabers remains the same as always.
MHXX's Stage 1 appearance shows her in high-tech full body armor with flight capabilities. Stage 2 removes the helmet, revealing an otherwise unchanged Mysterious Heroine X underneath with most of the armor pieces intact. Stage 3 has all of the armor removed (supposedly because XX made it invisible), instead wearing a two piece bathing suit, blue cap, and a small long sleeve blue shirt.
Since she is basically Miss Artoria without her serious components, X behaves in the shortest・fastest・simplest manner regarding anything. Contrary to her energetic, polite conduct, she has a hopeless personality that hates to lose (due being unaware of this herself, her inability to read the mood is staggering), challenges pretty much everything and does not give up until she wins. Still, since she "ultimately ends up working for the sake of those around her" due being good person by nature, things functioned well at the end of the day.
- Ritsuka Fujimaru
- Her partner on Earth. A reliable wallet. Since X has pretty much zero romance skill, she just treats them as a friend. Still, she will eventually notice that they are her precious someone and then let her chances slip up due some misunderstanding.
"What is this feeling in my chest... could it be that a Saber evil deity came to this planet!?" Fundamentally, she is the same as X. But due the self-awareness as a sheriff increasing her consciousness, she behaves more like an older sister than X. Since she belongs to a series from a few years later than X, she is like an office lady who became tired of daily life.
Serva★Fes 2018: Servant Summer Festival!
In combat, she uses the Rhongomyniad spear style, a deed that doesn’t fear even God. It’s a twin lancer style in which, when using the spear of light, the spear of darkness in the opposite side generates a backfire, and the opposite when using the spear of darkness.
- Existence Outside the Domain (Rank D): Protection from the Farthest Ends, the extreme point at the exact opposite position of the Outer Universe. As a result she became a Foreigner, but a Foreigner’s weakness is Foreigner so there’s no helping it. 「You throw a monster against a monster」
- Independent Action (Rank A): It’s unthinkable that she was a former Saber class, but she has inherited the skill she had in the class from before becoming a Foreigner without change.「That’s because, in severe missions, cool-headed self-assessment is required at times」, she herself is convinced with a triumphant look.
- Riding (Rank A): Not only can she do Cosmo-Surfing by riding the Holy Spear Armor Arvalon that has turned into flight form, but she can also steer the spaceship Stallion II.
- Cosmo Reactor (Rank B): The protection of the great Universe (plot armor) that draws towards herself victory’s principle of causality, but it has been ranked-down for being in the position of serving an organization.
- Suit Up (Rank EX): The protection of the Holy Spear Armor Arvalon. The armor always exists around XX’s surroundings as Spiritrons. To the quick work that materializes · arms this in minus 1 second (even if she receives a surprise attack, she goes back in time to one second before that and equips it), she has given the name of 『Suit Up』. Almost automatic. A fearsome skill that XX, who despite being a cosmic detective tends to oversleep in the mornings and is a recidivist of being late, has learned. Just a change of clothes skill. Actually it’s not really necessary to materialize it, it displays its function as an armor even in Spiritron shape. The BGM changes when using it… It has a sad anecdote in which she made that specification but it was rejected because that luxury wasn’t allowed for XX alone.「You’re a swordsman Don’t pull an Assassin Put down That unruly hair on your head」
- Detective's Instinct (Rank E): Revelation to determine the culprit. At a level that it’s better not to use it in case resolutions. It generates a load of critical stars, but at the same time XX herself deals with a star concentration minus. In some cases the demerit becomes a merit, it’s actually an excellent skill... She guesses the truth of the case with an 「I’ve got some insight!」, but it’s rank E so it becomes an incoherent conclusion. But that incoherent conclusion gives a revelation to the surrounding humans, and reveals the culprit after circling around. Generating a load of stars but not giving them to herself is because of this image.
- Justice of the Ends of the World (Rank A): Power from the 『boundary』 that is the forefront and farthest end of the Universe. It’s the power to bite a hole in 『void』, and the truth that expands the Universe itself. Adds invincibility penetration to herself, gains NP, and acquires 『special attack against Threats to Humanity』, truly a skill for the sake of a protagonist. Evil God Special Attack Artoria.

Comment from Illustrator
"XX has big changes with Ascension, and since there are almost no common parts between each Ascension design, I drew each Ascension separately. While thinking that all of the transformations are striking, so I hope everyone likes any of them… in the end, she become a somewhat awesome character. During the work her last Ascension is the one who covers the least, but seeing her popularity the smile is the best!" (BUNBUN)
