Bicorn

Encyclopedia Entry:
A variant of unicorn that has an alluring black coat and two horns. When a unicorn has sex with a non-virgin or her husband cheats on her, the man carries that woman’s demonic energy along her husband’s spirit energy when he pours it into her. Due to this, the demonic energy of the unicorn which had been kept pure becomes mixed with another woman’s demonic energy and gets corrupted, changing into the demonic energy of a bicorn, which in turn ends up changing the unicorn into a “bicorn.”   They have the same gentle disposition and graceful behavior as the unicorns, however, their true nature is exceedingly lascivious, and these monsters are regarded as “the symbol of impurity,” celebrating a lustful, hedonistic existence.

Though wildly lustful, they do not forcibly rape men, but they are adept in the ways of arousing lust in men. Men they go after will be unable to resist their sweet temptation, and will eventually have sex with them when seduced. Exactly opposite of the monogamous unicorn, it’s in their nature to prefer a polygamous harem arrangement where their husband has many monsters as wives. As far as they are concerned, their husband becomes a more lustful, hedonistic existence by having sex with many monsters. Also, letting many women know how the taste of their beloved husband in a harem arrangement brings them more joy than anything else. Additionally, their husband’s spirit energy, which gets mixed and corrupted with the demonic energy of various monsters, becomes like a cocktail, and it is said to be her favorite treat.

Normally, the demonic energy monsters pour into their husbands assert that they belong to them, and functions to repel other monsters. The bicorn’s demonic energy is different. The scent of the spirit energy of a man infused with it ends up becoming thicker and stronger. Thus, since he becomes extremely attractive and delicious looking to other monsters, it’s just the opposite. It attracts other monsters to their husband. Of course, this goes for the woman who caused them to become a bicorn, but if there are any other women who their husband desires, or if any women who desire their husband, they’ll train them into lascivious monsters that are appropriate partners for them and their husband, making them a member of the harem for their husband’s sake.

Even should their husband be resistant towards the idea of a harem, they’ll lure him into it by sprouting the seeds and fanning his desire for other women. Additionally, every time a new monster joins the harem, the bicorn’s demonic energy grows relatively thinner, so there is a limit on the number of people, but it’s probably easy to make a small scale harem of about 5 or 6 people.
