Magical Power

In the New World, there is a concept of Magical Power (魔力, Maryoku), but there is no concept of Magic such as releasing fire or water, and Magical Power is generally used as energy to reinforcement the body and weapons, and healing exists, but is difficult.

History
It is theorized by the Cult of Diablos that 10 millions years ago, the world of "The Eminence in Shadow" originally did not possess Magical Power. That is until the realms collided, with one of these realms pouring Magical Power into the world. The Dragons went extinct due to their inability to adapt to the Magical Power while the humans, elves and beastkin thrived.

Capabilities
The presence or absence of Magical Power is determined by talent, but it is not uncommon to have Magical Power, and it is possible to develop Magical Power with effort.

Fighting an opponent with Magical Power without Magical Power is a clear difference and can be called suicidal. For this reason, although there are several schools of martial arts, they can be won by forceful push with Magical Power, and from the perspective of Cid, who learned various martial arts in his previous life, pure fighting techniques have not been refined.

Because of the nature of Magical Power to dissipate uncontrollably as soon as it leaves one's body, the use of Magical Power to send out slashes of Magical Power requires an enormous amount of Magical Power and the ability to control Magical Power to a degree that is almost beyond the norm.

Magical Power can sometimes physically manifest itself depending on the user's skill, giving off colors and other visual depictions. People who can do this can create Special Techniques, what kind of power they possessed depends on the one who creates the Special Technique

Weaknesses
Constant abuse of magical power would result in magical overload in which the users suffer horrendous mutations unless they find a way to control their magical power.
