Magic

Magical Power (魔力), also known as Mana and Magic, is the source of every Blazers power.

Summary
Magical Power is a power which surpasses logic and is the power to change the world, though a person's magical power is determined and fixed at the moment of birth and it can't be increased no matter the kind of training a Blazer does in their life. Their limit in magical power is also explained as being the potential that the world would permit them with and Blazers who reach the peak of their potential wouldn't be able to get stronger than that, a number of them would even witness black chains holding them back. Though Edelweiss had further elaborated that despite all Blazers being prisoners of their fate, they were also protected by it and would be able to continue living their normal lives.

Desperados
However, there are individuals who ignored their fate, described as ignoring the warning of the gods and stepped outside of their fate; stepping into the domain of demonic beings through reaching their own Brute Soul or Awakening becoming a Desperado, beings who exist outside of the fate and as such are able to increase the upper limits of their magical power based on their training.

Pseudo Mana
Although normal Blazers cannot increase their magical power unlike Desperados, Blazers who are a part of the Natural Interference System (自然干渉系) are able to do so through amassing magical power from their respective elements turning it into pseudo-mana, allowing them to use more magical power then they normally could.

Usage
Blazers are able to use their magical power in a number of ways, like being able to increase their physical attributes such as their strength and speed through applying their magical power based on the magical power they possess. An example of this would be Stella, who has thirty times the amount of a normal Blazer and was could multiply all her physical attributes by five to six times and even more. Magical power is also required to power their Noble Arts.

There are also two known basic techniques Blazers are able to use:

Mana Defense: A technique, in which a Blazer is able to protect themselves from physical attacks and its overall effectiveness as well as its usage is based on the amount of magical power a person and/or their control. A Blazer that is almost constantly shielded by their magical power cannot be harmed unless struck by a person with equal or greater magical power.

Mana Emission: A technique, in which a Blazer releases their magical power in order to accelerate and improve themselves. This is a basic technique, which Blazers use unconsciously.

Training
Though there isn't any method for increasing ones' magical power, there are several other methods for training their magical power control. Several of these methods include using their magical power to control to mold a special clay and a method to train their mana emission by pushing the pistons of a huge press machine using their whole body, which is one of the basic training methods.

There are several difficult training methods. One example is running on a poll with the raging currents while also creating a scaffold that extends to the bottom of the poll using their magical power, which is among the most difficult to do.

There are Blazers who devise their own original training method.

Edelweiss devised a training method on the peaks of Edelberg, which has extreme frigid conditions 9,350 meters above seal level, where one concentrates their magical power inside of their body, then balance on the pointed end sharpened from the permafrost or else the point will pierce their flesh and bond. Edelweiss trained Ikki using this method so that he could regulate Ittou Shura, although, he couldn't hold for the full hour, she stated that he was able to increase its power threefold.
