Mamono Lord

The Demon Lord is the leader of all the monsters in the MGE universe. There have been multiple Demon Lords, and the title may have been held by very many monsters since the creation of the world. Previous holders have been bloodthirsty anthrocidal killers in the classical "monster" tradition, but the current incumbent, a succubus, is rather more a lover than a fighter.

The Demon Lord
The present Demon Lord is responsible for transforming monsters into the human-loving creatures we know of today, and is the mother of all the lilim. Other details on her personality and interests are sketchy, in spite of her central role in the MGE. One tidbit that is known is that she is an accomplished Devil Gem crafter.

Although all monsters would agree that the Demon Lord is, at least in a nebulous sense, their "leader", the degree of control she exerts over different factions and species varies considerably. For example, while the monsters of Zipangu appreciate and respect her for giving them female forms, they are in practice almost completly autonomous.

The current Demon Lord was merely one of the living things created by the Chief God, and had nowhere near enough power for it to be possible for her to overwrite the Chief God's settings. However, fortunately enough, because of several overlapping coincidences, she was able to achieve it. One was that she happened to be a succubus, a being that builds up power by having sex with men; one was that her current husband, who was the hero at the time, sympathized with her ambition and cooperated with her; one was that the monsters lent her their strength for some reason even though up to that point they had always fought endlessly amongst themselves, killing even their own kind in the struggle to decide a demon lord; and one was that just as in the case of the demon lord, a new Chief God took over, but she was a goddess who was still very inexperienced. The state of the present is the product of all these coincidences.

The Demon Lord's Utopia
Humans and monsters are beings that were created by god and ordained to kill each other. In this world, the blood of humans and monsters has been repeatedly spilled as they slaughter one another. A system that goes on ad infinitum was constructed. The leader of the monsters, the present demon lord, twisted the forms of the monsters that were established by god in order to break the loop and reshaped the world. Before introducing the last monster in this book, we'll introduce her vision of the world's future that she's trying to bring about.

The Demon Lords Objective
The demon lord's objective is to change all men into incubi, and change all women into monsters, thus bringing about the “unification of humans and monsters into one race.” In the completely unified race, the males will be humans, and the females will be monsters. She used the power of the demon lord which links the demonic energy of all monsters to channel her own demonic energy into them, changing them into the kind of monsters she desired, thus overwriting the settings for the monsters that original Chief God had established. In this way, “monsters” changed forms into “monster girls” that feel strong love for the male human men, mate with them and produce children.

However, the settings that had been determined by the Chief God weren't so weak that she could completely overwrite them with just that. A number of problems remained that the demon lord hadn't foreseen. Although their objective changed from killing and devouring flesh and blood, to mating and milking semen, the setting “monsters assault humans” remained. Additionally, since the setting “monsters are biologically superior beings to humans,” also remained, nothing but the monster girls who are both mothers and superior beings actually ended up resulting from the coupling of humans and monster girls, even though the Demon Lord had expected that the incubi, who are the males of the unified race, would also have been born. Because of this, the racial unification that the demon lord seeks is impossible.

Instead, the humans will probably eventually die out gradually just the way the present gods and Chief God insisted it would be. And now more than ever, the Chief God and demon lord's powers are locked in a bitter struggle. It wouldn't be strange if the balance crumbled at any moment. If the demon lord is defeated by the Chief God and she loses her life, the monster girls will revert to being “monsters” whose heads are full of nothing but the desire to kill and eat humans. Should it come to that, the happiness of the monster girls who married and settled with their beloved human men will be shattered, they will end up having to kill and eat their own beloved husbands with their own hands.

However, as for the demon's lord's power, every time the demon lord stores power, every time the monsters increase in number, and every time the demon realm expands, it grows stronger. If the demon lord's power continues to increase at this rate, eventually she'll be able to completely overwrite and establish the monster girls' settings. If it occurs, then incubi will end up also being born from monster girls. Human men and monster girls will seek one another, and then it can lead to the rebirth of a new human race.

Presently, it is said that the demon lord and her husband who is the human hero keep doing nothing but endless copulation deep within the demon lord's castle in order to build up demonic energy. They're an incubus and succubus couple, and the more they have sex, the more power they are able to grant to one another. Their power keeps rapidly growing more immense.

And one more thing: The demon lord's demonic power which is linked with all monster girls will grow bigger, however slightly, if you couple with a monster girl and give them your spirit energy. You are also one of those who holds the world's future and destiny in his very hands.
