Main article: Material life-form
Material life-forms ｢物質生命体, busshitsu seimei-tai｣ are life-forms that are completely dependent on their material body and possess no spiritual qualities or properties. They are only found in purely material worlds.

Demi-material life-forms
Main article: Demi-material life-form
Demi-material ｢半物質, han-busshitsu｣ life-forms are life-forms that are completely dependent on their material body, yet possess spiritual qualities or properties.

Humans
Main article: Human
Humans ｢人間ヒューマン, hyūman｣ are a species that, although weak at birth, and being born without any intrinsic skills, are high in number and specialize in aura-centric arts, making them able to defend themselves against innately stronger species despite their relatively small amount of magicules.

Demi-humans
Main article: Demi-human
Demi-humans ｢亜人デミヒューマン, demi hyūman｣ are a classification of species that are all closely related to, and able to breed with, humans. They can be largely put into two major categories with only a few exceptions. One is the sprites which are descended from fairies and include groups such as elves, dwarves, oni, and merfolk. The other is the beastfolk, all of which either fall under the umbrella of or are derived from lycanthropes and are a hybrid between humans and magic beasts.

Monsters
Main article: Monster
Monster ｢魔物モンスター, monsutā｣ is a catch-all term that refers to all magicule-based lifeforms. As magical beings, monsters do not require the essentials of normal life-forms — eating, drinking, sleeping, or breathing — and instead only require sufficient magicules for sustenance.

They can be broken up into two major groups: the mindless monsters which typically don't pay humans much attention and seek out prey with a large amount of magicules with the incentive of evolution and the intelligent monsters otherwise known as majin who tend to ally themselves with Demon Lords and their ilk instead of humanity.

Monsters commonly undergo evolutions that might drastically change their skills, intelligence, looks, and magicule capacities. In most cases the only requirement is reaching a certain level of magicules, but certain conditions must be fulfilled in some cases.

Magic beasts
Main article: Magic beast
Magic beast ｢魔獣, majū｣ is a term that refers to Monsters closely related to or evolved from animals, making up the large majority of monsters seen in the series.

Demi-spiritual life-forms
Main article: Demi-spiritual life-form
Demi-spiritual life-forms ｢半精神生命体, han-seishin seimei-tai｣ are a type of being that are, as the name suggests, a step below spiritual life-forms. They think with their spiritual body and make up the "lesser" species found within spiritual worlds. Examples include slimes and cryptids.

Enlightened
Main article: Enlightened
Enlightened ｢仙人せんじん, senjin｣ is a term used by humans to refer to those among them who have "evolved the correct way" and become demi-spiritual life-forms. The exact criteria for being considered one seem to be arbitrarily decided, but isn't incorrect to call any human or demi-human who has become a demi-spiritual life-form as an "enlightened."

Spiritual life-forms
Main article: Spiritual life-form
Spiritual life-forms ｢精神生命体, seishin seimei-tai｣ are a type of being that can think and act with only their soul and astral body. They're beings of pure willpower that typically reside within spiritual worlds but are occasionally born among or evolved from material and demi-spiritual beings and need a physical vessel to remain inside the material plane.

Saints
Main article: Saint
Saint ｢聖人せいじん, seijin｣ is a term used by humans to refer to those among them who have "evolved the correct way" and become spiritual life-forms. The exact criteria for being considered one seem to be arbitrarily decided, but isn't incorrect to call any human or demi-human who has become a spiritual life-form a saint.

Elementals
Main article: Elemental
Elementals ｢精霊エレメンタル, erementaru｣ are a major species among spiritual life-forms that are strong against daemons but weak against angels.

They're the spirits of nature and come into existence from collections of natural energy or as offshoots of a higher elemental. They feed off of natural energy to fuel their evolution, and when incarnated into physical form, they're collectively known as "fairies." Decipher this text
