Alp

Encyclopedia Entry:
A peculiar kind of Succubus unlike any other kind of monster, Alps are 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 subconsciously using the demonic energy he took in upon becoming an Incubus to destroy his spirit energy production function. As a result, they lose all spirit energy, and are no longer able to produce it. Now that the demonic energy is the only thing stored in their bodies, they end up transforming into an Alp.

Even after becoming Alps, their hearts, values, memories, personalities, and everything other than their bodies, are still the same from when they were men. Their bodies have completely changed into that of a woman, yet they self-identify as men. They may not even be consciously aware of the desire to become a woman that changed them into an Alp, or they may just be in denial, with the truth hidden away deep within their hearts. Because of that, they are shocked by the radical physical changes, and the huge gap between these changes and their male hearts 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, and will assault and copulate with a human man while in a state of confusion, torn between their desires and the resistance in their heart.

After getting a taste of a woman's pleasure, and the sweet taste of spirit energy, they’ll experience a powerful rush far beyond anything a human man could experience, and will become a prisoner of the ecstasy of sex with men, and the sweet taste of a man's spirit energy after the first taste. It will probably disturb their male hearts, which haven’t completely become a monster’s, but 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’ll completely lose all resistance to having sex with men, and will seek sex just as if inviting a friend to play, and will 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 hearts also change into that of a woman, and they become completely lascivious Alps who are more feminine than a woman, and more lustful than a Succubus.
