Black Keys

General Info

Black Keys logo
Item NameBlack Keys
Black Keys are iconic spirit weapons in the TYPE-MOON universe, often used by members of the Church such as the enforcer Kirei Kotomine. Made of blessed silver and shaped into a thin blade, these projectiles are known for their anti-demonic properties and ability to destroy spiritual beings. With enough skill and power, the user can manipulate even several Black Keys at once, effectively turning them into a swarm of deadly silver stilettos. Although they appear weak, their spiritual connection makes them strong, able to deflect physical attacks and inflict great damage on supernatural beings. As a symbol of the Church's faith and the embodiment of their sacred mission, the Black Keys are an invaluable tool in the fight against darkness.


The Black Keys are a known weapon in the TYPE-MOON universe, often associated with members of the Church, especially the Enforcers. They are sacred weapons produced when a conceptual application technique is applied to spiritually enhance the normal black key.
Mastery of these elusive weapons shows immense skill, often replacing the need for traditional weaponry. Black Keys are primarily used to combat supernatural beings, using the power of belief to inflict stunning damage that can immobilize targets or even cause death in some cases. In the hands of an experienced user, they also make excellent thrown weapons. Designed as long swords with a symbolic cross on the hilt, the black keys are visually striking and powerful. When disabled, they take the form of innocuous everyday keys that help hide them. However, they transform into a blade form when activated, making it a typical secret weapon.
So the black keys serve more than just symbolic purposes. They are the embodiment of the Church's power in the TYPE-MOON universe, a testament to their authority, faith, and ability to thwart the supernatural.

Creation and Development

The Black Keys were conceived by the creators of the TYPE-MOON universe as synonymous weapons for members of the Church, especially the Executors. During their production, great attention was paid to the symbolism associated with their design. The idea was to imbue the keys with an aura of divine solemnity associated with Christianity, given their use by the Church's soldiers.
The design emphasizes the paradoxical nature of the black keys, which represent the contradiction inherent in the enforcers of the Church, who, in defense of faith and purity, often plunge into darkness, fighting evil entities. The Black Keys they wield are seen as tools of purity and destruction, symbolized by their gleaming cross-shaped blades and sharp points, respectively. Having passed the development stage, the authors decided to simplify the use of these weapons. It was decided to use them not only as psychic, but also as spiritual weapons capable of influencing and haunting the metaphysical bodies of opponents. As a result, they were imbued with the ability to detect and corrupt the spiritual cores of supernatural beings, making them invaluable against the countless mystical beings of the TYPE-MOON universe.
The Black Keys are also designed to be thrown, extending their range, increasing the Enforcers' versatility. This feature was added to increase the tension in battle scenes by allowing for unexpected twists and turns, allowing church enforcers to attack from afar. It's clear that a lot of thought went into the creation and development of the Black Keys. Based on user roles, visual design and versatile capabilities, they have all become an integral part of the TYPE-MOON universe.

Cultural Impact

Sorry for the confusion, but it looks like the Black Keys aren't part of the TYPE-MOON universe. The TYPE-MOON universe revolves around anime and video game series such as Fate/Stay Night, Tsukihime, and Melty Blood. If you're asking about something in the TYPE-MOON universe, can you name it? Or if The Black Keys you're talking about is an influential American rock band, I should write about their cultural impact outside of the TYPE-MOON universe.
