Monster

Monster (魔物) is a term that refers to all Magicule-based life-forms. As magical beings, monsters do not require the essentialities of normal life forms—such as eating, drinking, sleeping, or breathing—and instead only require sufficient magicules for sustenance.

Monster Origins
There are three manners in which a monster may come into existence.


 * Spawning, where the monster is born out of the Factor and magicules either latent within the surroundings or let off by a "parent" monster.
 * Biological Reproduction that has either a singular monster or a pair of compatible monsters engage in regular biological reproduction.
 * Mutation of non-magic lifeforms—plants, animals, humans, demi-humans, spirits, or mystic beasts—into magic lifeforms. It occurs when the subject is exposed to more magicules than it can handle. While this would normally result in death, they can occasionally be reborn as a monster.

Majin
The term "Majin" refers to monsters that possess proper intelligence and rational thought similar to humans and demi-humans. A monster can be a majin from birth (such as Vampires, Giants, and Daemons), become one later in life via evolution, or be born by the monsterization of an already intelligent lifeform, i.e Humans and Demi-Humans.

Named Monsters
Named Monsters (名持ちの魔物) are monsters who are Named. Named monsters usually have a much easier time acquiring skills and have almost always evolved into a higher race.

Unique Monsters
Unique Monsters (ユニークモンスター) are individuals of a particular race of monster born with certain characteristics, traits, or abilities not found within the typical member of their species. These individuals are usually much stronger and smarter than their ordinary counterparts. Examples include the Orc Lords and Rimuru Tempest.

Trivia

 * While many Demi-Human races, such as Goblins, Orcs, Lizardmen, and etc are often called "Monsters" the term used for them is Demonic Tribe (魔族) which collectively refers to intelligent enemies of humanity regardless of their status as magical beings.
 * As there is no set standard for members of their race and because of the circumstances behind their birth, True Dragons are each individually considered "Unique Monsters".
