Purification (浄化, Jōka) is a technique used by Feodor using Demon Cannon.[1]
Description[]
Purification combines the Meister's physical prowess (such as Feodor) as well as the Anti-Demon Wavelength of the Demon Weapon (like Tsar), the attack "purifying" malicious forces such as Black Blood. This attack has been commented by Medusa Gorgon to be achieved via "perfection through unity".[2]
