Many know about essence as the thing that Monster Girls like to drain from men, feeding on it, and rendering them unable to fight back.
But what exactly IS essence? Why do Monster Girls love it so much? And why do men go weak when it is drained?
In simple terms, Essence is a form of Life Force, Qi, Yang Energy, Positive Energy, Life Mana, Vigor, or any other name one could come up with.
Every non-monster creature has a form of Essence within, and each essence has a special life signature belonging to an individual. Meanwhile, Monsters have a form of Monster Energy, which is said to be the opposite of Essence.
Humans, being creatures of order and light, are encouraged by their blessing to consume Monster Cores, growing stronger in the process and having a united front. Meanwhile, Monsters, being chaotic and dark, eat humans and monsters alike to grow stronger, lacking proper cohesion.
And then there are Monster Girls, who are said to possess both Essence and Monster Energy, which is why they can have two Primary Classes instead of one. However, this comes with a price... The source of this chapter is g.com.
Where humans and regular animals can produce Essence in large quantities, Monster Girls innately have an essence deficit due to their Succubus heritage, a race of parasites that feed on human essence, especially males. And as it happens, male semen contains an abundant, concentrated amount of essence, which succubi adore.
Because of this, Monster Girls sexually prey on men, raping them to extract their semen... their essence. In a normal ejaculation, men release excess Essence, which isn't harmful to the men. But if a Monster Girl uses Essence Drain, they draw out the inner essence that helps the man survive, which is why the body would prioritize producing more essence.
Moreover, they would also inject their succubus-like Monster Energy into the man, which renders them both aroused and subservient to the Monster Girl until the body gets rid of it. This causes the male to fall into a helpless state where they are repeatedly raped, producing essence-rich semen for the Monster Girl, much like a cow producing milk. In the other continents, it is even rumored that they have literal male milking ranches there with an industry revolving around male semen. Get faster updates on NovelPing.
However, if the man is their proper husband, the Monster Girl wouldn't do that. They say it is because a man's essence tastes best when it is all-natural... As well as not wanting to cause harm to the man they love... Although there are some reported isolated cases of some helpless perverts actually wanting to become semen producers.
On the other hand, human females are far less attractive to Monster Girls, to the point they might outright ignore them. It isn't because their essence is weaker, but their nature is closer to a Monster Girl's. This is also why Monster Girls can transform human females into Monster Girls, as they can mutate the very essence of a human woman, shutting down their ability to produce essence while flooding them with monster energy, converting them to their race.
It is said that the change is so intense that the woman would undergo a rejuvenation process, returning to around 18-20 years old, which is why many middle-aged and elderly women seek to monsterfy themselves, even if it means becoming a subordinate to a stronger monster and a weakening of their original class. They would also lose their human restraints, attacking men like their progenitors would, and often with less restraint, regardless of their past.
Either way, men with strong essence, be careful out there! You are like a lighthouse in the middle of the night for these hungry women!
