Spirit Energy is what we would typically call "mana" or "chi". Or, more specifically, it is one kind of mana or chi, and is most closely associated with males.

The other kind is Demonic Energy, and is likewise associated with females.

The two operate on a sort of yin & yang principle, and are completely co-dependant on each other. One cannot exist without the other, and all that, sort of how men would disappear if there were no women, and vice versa.

When a monster feeds on a person's Spirit Energy, she is also feeding that person some of her own Demonic Energy. If the person is a woman, this influx of Demonic Energy will eventually destroy her ability to produce Spirit Energy. Her body will become full of Demonic Energy, and she will become a monster(usually of the same type as the monster that ate all of her Spirit Energy).

For men, however, this influx of Demonic Energy has a completely different, opposite effect. Instead of destroying their ability to produce Spirit Energy, it enhances it. They produce Spirit Energy in greater quantities and concentrations. Eventually, this constant influx of Demonic Energy will transform them into an Incubus, which is basically an improved version of humans. They produce Spirit Energy in vastly greater amounts than normal humans and gain other perks, such as an increased healing ability among others.
