Alp

Encyclopedia Entry:
A peculiar kind of succubus unlike any other kind of monster. Male incubi who suddenly transformed into female monsters. Since men ordinarily have spirit energy production capability, even when they’re infused with demonic energy, they don’t turn into monsters. Though the incubi are often treated as monsters, when it comes down to it, they are merely humans warped by demonic energy. However, when an incubus strongly desires to become a woman, or be with men from the bottom of his heart, he ends up unconsciously using the demonic energy he took in upon becoming an incubus to destroy his spirit energy production function. As a result, no longer able to produce spirit energy, they lose all spirit energy, and only demonic energy ends up stored in their body. They end up transforming into the female alp monsters.

Even after becoming alps, their hearts, values, memories, and personalities, everything other than their bodies, is still the same from when they were men. Their body has completely changed into that of a woman, yet they self-identify as men. They may not even be consciously aware of their desire to become a woman which changed them into an alp, or they may have been in denial, with the truth hidden away deep within the heart. Because of that, they are shocked by the radical physical change, and there’s a huge gap between it and their male hearts, which probably makes them feel bewildered. For that reason, most of them feel resistant to having relations with human men as monsters.

However, once the monster’s instinct starts to take root, their bodies and hearts are naturally drawn to human men, and they’ll start to desire intercourse. Eventually, they’ll become unable to stand it, assaulting and copulating men with a human man while in a state of confusion torn between the desire and resistance in their heart.

And then, after getting a taste of a women’s pleasure, and the sweet taste of spirit energy, they experience a powerful rush far beyond anything a human man could experience.

They become a prisoner of the ecstasy of sex with men, and the sweet taste of men’s spirit energy after first tasting it. It probably disturbs their male hearts which haven’t completely become a monster’s. After repeatedly having sex like this, the desire to seek men becomes even stronger. Eventually, even with their self-awareness as men almost completely unchanged, they completely lose all resistance to having sex with men. They seek sex just as if inviting a friend to play, and start to enjoy the ecstasy and taste of spirit energy.

Also, through this process, there are alps who awaken to the joy of becoming a woman, and in that case, their body rapidly becomes more voluptuous in order to seduce men. Their heart also changes into that of a woman. They become completely lascivious alps who are more feminine than a woman, and more lustful than a succubus. Encyclopedia Pages
