Backstory

Assassin is the Assassin-class Servant in the FC/OC Holy Grail War One-Shots. Her true name is unknown, to the point where even she does not remember her original name. However, upon arriving to Earth by a doctor named Masahiko Ogai, she adopted the name Saya after the doctor's childhood pet. Saya is an extra-dimensional creature that looks more like an Eldritch Abomination than anything else, with an instinctual goal implanted in her race to infect whatever planet they're on with spores to turn whatever living thing there into her species. However, instead of doing so, Saya began to read literature and begin to learn more about humanity, eventually wanting to learn what love is.

After Dr. Ogai went missing, Saya went to the hospital to search for him before fatefully encountering who would eventually become the love of her live, Fuminori Sakisaka, who saw her as a regular human girl instead of an Eldritch Abomination because of a mental illness he had. The two began to live together, with Saya's feelings growing more and more with Fuminori's kindness, to the point where she forgone her instinctual quest to infect life entirely to cure Fuminori and search for Dr. Ogai.

After curing Fuminori, she left him; not wanting him to see her hideous true form, and ventured in search for Dr. Ogai. It was in this fruitless search that she eventually died alone; not being able to see her beloved ever again.

Over the course of a battle, she could swiftly learn how to defeat an opponent and use their weaknesses against them, even without formal combat training or knowledge.

Notable Attacks/Techniques:

Noble Phantasms

Unidentified Species: Fear of the Unknown: Saya is an alien from another dimension whose true form is comparable to that of an Eldritch Abomination; so much so that a normal person will go insane just from seeing her. The one thing that drove her actions (aside from a genuine love for a man when she was alive) was her instinctual mission to convert everyone on the planet into beings like her, however, she has long forgone even this; drifting around pointlessly until her own demise in life. This is an Anti-Unit/Anti-Team A-rank Noble Phantasm aimed at making all enemies that look at her or are in contact with her for a certain period of time to go insane. This is not Magecraft, but instead her own looks being so incomprehensible that anyone near her would go insane anyways, to the point where they'd drop their weapons and begin to question whether any of this is even real; not even going to attack her. Eventually, it will come to a point where they become so insane that they see Saya as a little girl instead of as an Eldritch Abomination, meaning that they will not be able to see her tentacle/flesh attacks. However, this Noble Phantasm can easily be countered with good mind resistance, have shown feats of good mental willpower, or already being insane/mentally ill (those insane though will see her as a little girl, thus unable to see her tentacle/flesh attacks).

Saya’s Song: A Tune For the One to Birth the Many: An Anti-World EX-rank Noble Phantasm that Saya refuses to use. It is the ultimate ability used to complete her original instinctive mission to convert everyone on the planet into Eldritch Abominations like her. Saya begins to bloom like a bright white flower, birthing never-ending spores to infect all living creatures on the planet and transform them into creatures like her. In the process however, Assassin is immediately slain.

Class Skills

Presence Concealment: The ability to hide one's presence as a Servant. Saya's A-rank proficiency in this skill renders her nearly impossible to detect even in the perceptive eyes of a Servant. But when she decides to attack, this skill's effect sharply drops.

Personal Skills

Monstrous Strength: An ability possessed by monsters and beasts that allows Saya to increase her physical strength beyond the norm, giving her an edge in combat.

Natural Monster: An ability endowed to those who were given birth as a monster rather than a hero or god that has fallen down to the level of a Magical Beast. For Saya, this skill boosts her Strength and Endurance to levels superior to most regular Servants.
