A type of fairy with a peculiar nature. Aside from living in places such as forests among other fairy type monsters, there are also many who change into human form and slip into human settlements. They love works of art such as pictures, music and stories; and will appear before the human creators of such works after being attracted by them.
They have an extremely unique diet. They touch excellent works of art and feed on the energy dwelling within them. They also love to personally produce art. Aside from creating their own works, they will assist humans they're fond of with their work.
Also, they are very aggressive in romantic pursuits. When one of them takes a liking to a work of art, she will be drawn to the human man who created it, and will try to actively seduce him to become her lover. They appear like very young little girls, but a subtle charm magic is always being released from their body, so the men they target will always feel extremely attracted to them. It is extremely difficult to elude their seduction.
Also, some Leanan Sidhe have become monsters due to the influence of the succubi. They are extremely lustful, and after becoming a man's lover, they will actively seek sex. Furthermore, they will start to appreciate things such as sensual works of art as well. After enjoying sensual art with their lover and increasing their lust and arousal they very much like to lash out at one another's bodies with that arousal and have sex.
After becoming monsters, to them; obscenity, having sex with men influenced by obscenity, and the stuff that's poured inside them when they do so, are all unbearably sweet. This is even more true if their lover is a producer of erotic art, and they themselves will be enthralled by their lover's work. Sex with their lover will be so sweet and happy, that it will fill their head with their lover and his work.
A man who has sex with a Leanan Sidhe has his creative abilities and talents for art skyrocket. Thanks to this power, most such men have become rich and famous. However, their minds are gradually twisted by the charm magic. Eventually, they can think of nothing other than her, and producing works of art to give to her.
Eventually, even the wealth and fame brought by their works will feel like an annoyance, and they will disappear and head off to the fairy kingdom with her. It is said that in the fairy kingdom their life will consist of nothing but producing works of art and making love to her.
