Mysterious Executor C.I.E.L

A vampire hunter vacationing on Earth, a beautiful teacher who provides hints after the Game Over screen, and a saintly idol known only to a select few in the Sapphire Galaxy... Her true identity is Space Ciel, Executor and executioner of planetary vampires.

"Misaki? Souya City? I haven't the slightest clue what you're talking about. I'm just a tourist who happened across Earth, you know. (Smile)"

What connection, if any, she has to the Ciel from the world of "Tsukihime" remains shrouded in mystery.

Height/Weight: 165cm, 52kg

Origin: Tsukihime, Fate/Grand Order

Region: France, etc.

Alignment: Lawful-Good

Sub-Attribute: Human

Gender: Female

Ciel from the Servantverse...or perhaps a Ciel from a future world. It's a little vague.

"Does it really matter? Either way, I'm a benevolent Executor here to eliminate troublesome vampires!"

Personality

Outgoing and proactive, cool and rational, she treats everyone as equals, though she is harsh with villains and the immoral. Ciel is a natural-born disciplinarian and champion of justice and possesses extraordinary endurance; one vampire described her as an "iron lady" for her unyielding resilience.

She's the type who finds happiness in seeing those around her happy. To achieve this, she is generally rational and proactive, and occasionally calculating. She never gave much thought to her own happiness as a child. After growing up, she simply stopped thinking about her childhood altogether. Consequently, she has came to be defined solely by professional duties, leaving no personal desires of her own. Should she ever encounter something she truly desires, her inner strength and intensity would be channeled entirely toward securing that object's happiness.

Her excellent work ethic often makes her seem mature, yet she retains childlike traits as well. She might occasionally act a little mischievous, out of a playful desire to be noticed or to tease someone she likes. When acting as an Executor, she suppresses all human emotion, becoming a cold, calculating machine focused exclusively on accomplishing her objective.

Magic Resistance: A

She takes no specific countermeasures against magecraft, but her immense internal magical energy generation naturally repels most spells.

Independent Action: EX

Her vast magical energy production allows her to engage in combat without any energy supplied by a Master or the world around her. She can materialize in the physical realm even if her link to her Master is severed, leaving one to wonder if she needs a Master at all.

Auto-Regeneration: A

If she is wounded, the damaged parts of her body automatically regenerate. Previously, the regeneration was more spiritual than physical, but upon clearing a certain quest, that curse was lifted.

Gift_Clarion: -

The exceedingly rare talent of [censored]. A certain department within the Church said it was "as if she was blessed by an angel at birth." To a certain mage, it was merely a congenital defect. Does not manifest in FGO.

Human Magical Energy Plant: A

Derived from her Natural Body. This perfect, indestructible body generates vast amounts of magical energy within itself.

Ciel doesn't like this skill name much.

Phase-Gliding Blade: B+

A sword technique devised to kill vampires. As the monk who created it said, "the soul lies in sound." Souls are higher-dimensional phenomena that cannot normally be interacted with, but their waves can be captured, as he put it. A divine-realm shock transmission technique that penetrates even ethereal bodies despite being a physical attack. For vampires, blood and soul are synonymous; any undead struck by this sword has their internal blood (their life reserve) depleted by it. Perhaps because its creator was a swordsman, this skill only works when used with a sword.

Idea Blood: B

The adoption of a textural rule seed (Principle), known in the world of magecraft as the world egg theory. The Principle does not simply grant transcendent abilities, but instead manifests change based on the characteristics of the life-form possessing it. For Ciel, this manifests as having the power to take on the world, even though she remains human.

『Code: Original Sin』

Rank: A+

NP Type: Anti-Personnel

Range: 20–99

Maximum Targets: 1

Seventh Holy Scripture: Death by Execution

Restores a portion of the Space Seventh Holy Scripture to its original form, transforming it into a massive ballista before firing. Ciel's all-out one-shotter, a strike that defies reality. Its sheer destructive power (spacetime penetration) alone is said to be capable of piercing a planet, though outside the Sapphire Galaxy, it is scaled down to a more conventional scope.

『Calvaria Galgalim』

Rank: A+

NP Type: Anti-Personnel/Anti-Planet

Range: 999

Maximum Targets: 1

Idea Blood: Guillotine

Idea Blood No. 25. A grand magecraft devised by the Executor Ciel when she defeated her own sword teacher, known as the Star of Calvaria. A guillotine of light that deploys a magically-created reflective mirror in the stratosphere, concentrating and releasing sunlight. As long as the target on the ground can see the Star of Calvaria, there is no way to evade the guillotine that falls faster than an eyeblink.

Concept: What if Ciel existed in the Servantverse?

Essentially Ciel from "Tsukihime -A piece of blue glass moon-," but her armaments are amped up in power to fit the sci-fi setting.

Shining Ciel, her third Spirit Origin, is her form after activating Idea Blood in the Servantverse. Footage of her smashing a planetary-type vampire species with her pile bunker leaked across the cosmos. Her dignified grace, delicate beauty, and cool cuteness instantly earned her recognition as the idol of the universe.

Since then, quests where Ciel is eliminating planetary vampires have been dubbed "Star Lives," with fans hurriedly warping to those star systems. The cost of space housing has skyrocketed in these places as a result, sparking fierce competition for seats at the show. The tiny crown floating above her head is proof of her "saved the galaxy once" achievement. Any member of the Galactic Police would bow down in awe just seeing this crown.

Her third Spirit Origin is composed of a pseudo-light frame...in other words, Ultra Ciel.

"Huh? Why'd it turn out like this?"

"Because it was burned down to the atomic level in our final battle!"
