This is a brief guide to better understand how the Demon World currently works in My Wives Are Beautiful Demons.

I've combined elements from worlds I enjoy creating, so yes, there are inspirations from other works. However, this world is not limited to that. I hope you can understand and enjoy reading.

[A Summary of the Demons' Past]

Demons are divided into two main branches: Pureblood Demons and Reincarnated Demons.

Demons are beings that originated from the Netherworld, created by the Original Lucifer using the body of his wife, the Original Lilith, to create a superior force to deal with and destroy all Angels, as well as to fulfill his personal ambition of world domination. This force consisted of High-Class Demons from the 72 Pillars, created from Lilith's vital essence and used as Lucifer's personal army.

However, things didn't go as planned, and Lucifer was sealed away forever at the end of the Great War of Genesis, marking the beginning of the Great Demon Era.

Four Great Demon Kings took leadership of the demons after Lucifer's fall, and thus, the Netherworld entered a new regime. Despite many wanting to continue the war, the current Demon Kings subdued those who sought rebellion, leading to the Great Demon War, also known as the Three-Sided War, which was the war between Angels, Fallen Angels, and Demons, who were drawn into the chaos of the Netherworld. In the end, it led to an era where demons stood alongside all races.

After the war, with the subjugation of the demons who continued trying to restart the Genesis War, the demons joined forces with witches to establish a new race, demons who just wanted to live their lives. Thus, they created the Contract System to transform beings into demons using the Demon Goddess Lilith, whose body was found and studied after her fall alongside Lucifer.

[Appearance]

The majority of Pureblood Demons resemble humans, though they still possess demonic traits like bat-like black wings, which can be hidden at will. Of course, there are demons from specific bloodlines that may have much more unrealistic modifications compared to demons that resemble humans.

But naturally, demons are capable of using their Demonic Powers to appear as other races, as well as to appear much younger. Additionally, there are demons that seem to have characteristics of creatures and monsters.

[Abilities]

Physical: All demons possess enhanced physical abilities, such as superhuman strength, stamina, and heightened senses like sight and hearing. They also have vision adapted to any environment, no matter how dark it is; they will always see clearly. Demons can fly with their wings, which, despite being small in some cases, can retract into their backs as if they completely disappear.

Magic: Demons also have the ability to conjure magic, using Demonic Runes, and they've developed their own Demonic Magic system powered by Demonic Power.

Bloodline: Pureblood Demons can inherit special innate abilities unique to their clan, although occasionally, the offspring of members who marry outside the clan may also inherit these abilities, making it a common practice among the remaining pillars.

Some Common Spells Demons Have:

Language: Ability to learn any common language.

Summoning: Summoning of Familiar Spirits.

Elemental Demonic Power: Air – Water – Earth – Fire. [Derived from Bloodline]

Appearance Manipulation: Complete Transfiguration.

Mind Control: Charm, mainly works on non-magical beings.

[Demon Differences]

Pureblood Demons: Superior species, their entire existence is more abundant, from their reserves of demonic energy to their innate abilities. They also have the ability to generate new demons through contracts.

Reincarnated Demons: Inferior species, their entire existence depends exclusively on their Master; they see their master as a King. Additionally, they have higher fertility. Their abilities depend solely on their soul and talent, unlike Pureblood Demons who have a defined bloodline.

Stray Demons: These are reincarnated demons who have strayed from their masters due to their own selfish desires. Without their masters to keep their powers in check, they become a great threat if their powers go beyond their control. Demons take this issue very seriously, and any demon that becomes a runaway is usually killed on the spot. Often, these demons, due to being unbalanced, become grotesque monsters.

In the future, with the introduction of more characters, new and creative ideas will be added. Remember, this doesn't completely reflect my vision of the work.
