Lisiah is a priestess. Somewhat, at least. She poses as one. Because she is the daughter of a succubus and a god. Why is she posing as a priestess, you ask? Because it's easier to seduce people who jump at you under the illusion of you being innocent and harmless, of course! Her goal is to become an evil goddess and for that she fully embraces her demonic side. After all, who wouldn't want to worship a cute and innocent girl?
This is a rather lighthearted story, so don't expect an incredibly deep plot.
Also of you don't like Yuri or FxF don't read this story. The protagonist is bisexual, meaning there will be male and female lovers.
A good story so far, would make a great anime! I wish the writer would polish up the writing a little bit though. Hope the next installment comes out soon!
