God

God (神, Kami) usually refers to a higher being, often with immense power and influence, and usually the subject of worship by religion. There are different concepts and interpretations between religions, and the nature of what a God is often varies between them.

Principles
Due to the rise, spread, change and decline of various religions around the world, various gods from one religion or traits associated with them are often assimilated into other religions. In some cases, such as with the spread of Christianity, pagan gods of old may be reclassified and reduced to the role of fairies or demons.

Common concepts
In many religions and mythologies, gods possess immortality.

In certain religions, gods are said be absolute, possessing traits such as, and. Others have gods which are not absolute but still possess high levels of power. In many cases, they are attributed with having created the various aspects of the universe.

Relationship with humanity
Gods are the subject of worship by religion, and receive prayer, offerings and dedications from the followers of those religions.

In most religions and mythologies, humankind cannot defeat gods, but instead they may attempt to negotiate with them through offerings, prayers and the like to overcome difficult situations and slightly alter their path to something closer to what is most convenient for them.

Christianity
The various factions of Christianity all worship the same God, considered to be the one true God. The doctrine known as the Trinity defines God in three persons but at the same time the same one God, these being the Father, the Son and the Holy Spirit.

Norse Mythology
The gods of Norse mythology, like many polytheistic religions, are not absolute and have emotions much like humans, both positive and negative. Gathered together, the gods compensated for each other's weaknesses, creating a sturdy and flexible system. Unlike in certain other mythologies, the Norse gods are capable of being killed and many of them will perish during Ragnarok.

It is implied that certain Norse legends, particularly those concerning the chief god Odin, may have been influenced or derived from the actions and power of Othinus.

Shinto
In Shinto, the concept of god (or kami) is a broad and changing one, and there are many different beings, including various deities, spirits and phenomena, that are revered and worshipped as such. Harming one is considered manageable but highly frowned upon.

Magic Gods
Majins, or Magic Gods, are magicians which have mastered magic to the degree that they can bend all things in the world through magic, transcending normal magic and stepping into the realm of God. This position, with the title of a god, is one of the highest positions, if not the highest position a Magician can reach, though the chances of one reaching that position are extremely remote.

Encompassing every possibility, a Majin is capable of distorting the world to their whim. However due to encompassing every possibility, both positive and negative, Majins initially have an equal chance of success and failure with their magic. Impure or failed Majins who've stopped their growth before this point lack this problem but don't have the power that a pure Majin would have. Once these possibilities are united in one direction however, a Majin can freely change the world and everything in it as they please with their power.

Being in a position with the title of god, those possessing the qualities of a Majin, such as Othinus and Ollerus, are unaffected by certain spells which would affect humans, such as the Einherjar spell, while certain other spells, such as the "Turn into a fairy" spell, are specifically designed to target them. In the case of Othinus, a pure and perfect Majin, they have also been shown to possess lifespans far beyond that of humans.

Other
There are many other religions which revolve around gods and similar beings; monotheistic, polytheistic or otherwise. Between these religions, certain similar systems share similar characteristics. In polytheistic religions, every god possesses a name and role which they are meant to carry out, and gathered together form the gears making up the system of their mythologies.

Aside from magic based off religion and mythology, there are a few other forms of magic, some of which are fairly recent, which make use of the concept of gods and very similar ideas. The cosmic horrors of the Cthulhu Mythos for instance, are considered evil gods which no human can stand up against.

Despite most religions and mythologies holding that humans cannot defeat gods, there are forms of magic designed to fight some gods or at least pacify them. Ollerus's Fairy spell is one of them, based on Christianity's tendency to reduce pagan gods into fairies or demons, and meant for use against Magic Gods. Another is a technique of Aleister Crowley, who has an immense hatred for the Magic Gods as well as the God said to be the creator of the world and its rules. Used by Kihara Noukan through the Anti-Art Attachment, it channeled Aleister's willpower in a form capable of destroying a Magic God. Aleister also made use of a spell which severely weakened the true Gremlin, using the Magic Gods' base parameters and swapped out with their own spell. Kanzaki Kaori was able to make use of the aspect of Shinto involving the possibility of being able to harm gods, applied to fighting divine beings from another religion such as Christianity (though in this case, it was used against Archangel Gabriel rather than God), to a certain extent.
