Daemon

Demons (or Devils) [悪魔, Akuma] are existences like spirits or angels. They received power from the spirit of Darkness and specialized in demonic attributes. When they do not have a body they exist in the Underworld (Hell) where most wander aimlessly. Also the majority of the Demons do not have names or any sort of attachment to themselves. There are a few exceptions which include those that have developed an ego after being summoned several times and having contact with the world.

Demons will fight constantly by shooting energy at each other. As they fight more they will evolve and get stronger. They can also gain Unique Skills.

However it takes a very long time of constant fighting to evolve even from a lesser demon to a greater demon. Making those of even higher ranking even more rare.

Summoning
It means to be summoned from the Underworld (spirit world) to the material world. There a temporary body could be obtained and the pleasures of the surface could be experienced (smell, touch and taste).

A summoned demon without an ego would be affected by the personality of the summoning master. Depending on the summoners request the Demon could receive a lump of information called a Soul and with enough souls collected the Demon could evolve into a higher being.

Summoning chooses the appropriate demon(s) with the appropriate rank for the tasks. All of this occures naturally.

Once in the material world first an Ego arises. Each summoner provides more information to the demon allowing them to become more powerful with each summoning.

Other Information
To stay in this world a Demon needs a body; animals and monsters are often used to that end.

Demons are being which are generally summoned into this world as spirit being that need to occupy a body in order to remain.

However it is possible for monsters (Demi Human and Magic Beast) to evolve into Demons given that they are strong enough and have had enough time to evolve.

Demons are often referred to as Devils.

 * Great Demon Lord: A being known to have multiple True Demon Lords or Demon Lord class beings as their subordinates. A clear difference in standpoints.
 * True Demon Lord: Just like the name suggests, they are the individuals that have sprouted their Demon Lord's Seed and thus, have been approved of by the Voice of the World to be titled 'Demon Lord' in it's truest sense. Their strength are in a completely different caliber compared to the 'self proclaimed' Demon Lords.
 * Demon Lord: This refers to any species possessing fearful might and notoriety. They do not possess or have not yet sprouted their Demon Lord's Seed. As such, some are also called 'self proclaimed' Demon Lords.
