Magical Power

Magical Power (魔力) or Power (魔力) refers to the energy used to perform a wide variety of actions within the series, such as manipulating Magicules, activating and maintaining the use of Skills, casting Magic, and Naming.

Properties
Magical Power is in and of itself not a specific type of energy, but rather the aggregate of several different energies. Its comprised of the Material Body's Energy (生命力) and the Spiritual Body's Energy (精神力), with the Soul's Soul Power (魂の力) likely also falling under this categorization.

Magical Power can be considered analogous to stamina, with a state of low magical power resulting in physical exhaustion or mental lethargy. It can be recovered in the ways that one would expect going by this description, with sleeping and eating being the most common among them. Additionally, for those that have a sufficient tolerance towards Magicules, it is possible for their bodies to metabolize an excess amount into energy, which results in a rapid restoration of expended magical power.

In extreme cases, the depletion of magical power past a certain limit can result in permanent damage or even death. However, given that most individuals would pass out long before reaching this point, this is an extremely rare occurrence. This typically only happens if one's magical power is being drained by an outside source. Similarly, if one's physical condition becomes impaired such as by neglect, damage, or aging, their magical power will decrease.

When a being is utilizing their magical power, it is normal for it to leak out of their body and into their surroundings in the form of waves. It is also possible for someone to imbue their magical power into objects, allowing for the activation of magic by someone incapable of even casting it, even if it has a limited number of uses.

The exact wavelength of an individual's magical power is different from person to person, similar to a fingerprint. This allows for those more sensitive to magical power and those possessing the Extra Skill Magic Sense to identify individuals based purely on their magical power regardless of their physical appearance.

Magic Circuits
Magic Circuits (魔力回路) are a type of pseudo circulatory system found within the bodies of beings like Majin and Spiritual Lifeforms.

While for normal lifeforms like Humans and Demi-Humans their magical power is stored within their blood and runs through their circulatory system, magical and spiritual beings which have an abnormal physiology instead have Magic Circuits to circulate energy through their bodies.

It is possible for these Magic Circuits to be interfered with and blocked by effects such as curses and advanced applications of Fighting Spirit. This will make it difficult to accumulate energy and slow down the healing process.
