Soul Metal (ソウルメタル Sōru Metaru) is a mystical metal alloy commonly used by the Makai Order to create weapons and armor in their battle against Horrors.
Background
The origin of Soul Metal is tied to the legend of Zedom. After Zedom's defeat, the Makai Order utilize the seeds that germinate into Madō Horror Plants to produce Soul Metal. In time, due to Soul Metal's resilience and ability augment the physical abilities of the user, various weapons are crafted from it as a means to slay Horrors with the armor of the Makai Knights being the end result.
Description & Characteristics
Unlike ordinary metals, soul metal responds to the wielder's strength and thoughts; a trained body and a strong will are required to effectively wield anything made out of Soul Metal. Soul Metal's potential is based on the wielder's will. Taiga displayed he can make Soul Metal light as a feather or heavy as a meteorite. These weapons, however, require purification after being used to slay a Horror. Normal humans without sufficient will and training cannot lift Soul Metal of any visible size. Direct contact by those untrained in its usage will lead to injury, as it burns flesh due to its magical properties. As with other qualities, sharpness of Soul Metal blades are dependent on the wielders, at trained hands these blades are able to slice through solid rock with almost no effort. When a Makai Knight falls into darkness, the Knight's Soul Metal turns into Death Metal (デスメタル Desu Metaru?).
