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 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.
