Seventh Holy Scripture
A treasured holy relic created by the Holy Church to demonstrate the Lord's power, though for a long time there was no one to use it. The embodiment of a miracle crafted by human hands. A conceptual weapon structured into a scripture a thousand years ago by luring a rare phantasmal species still lingering on the surface and forging divine iron by casting the girl who served as a lure into the fires of the furnace.

Soul-smashing ー that is, starting with execution, all the possible causes of death that may befall a human are inscribed, while the divine iron's natural frequency chants a baptismal admonition against them.

The combined form of the six armaments - dual guns, bayonet, great sword, armor, and the core - assembled onto the horn of a unicorn is operated as a mobile anti-vampire weapons platform, and when further deployed it can also transform into a ballista.
