今宵、妖しい口づけを ～雅・京牙・沙門編～

You’re an average 25-year-old girl, working at the library to make ends meet and support your family’s shrine. However, that all changes when handsome men save you from malevolent spirits! It turns out, though, your saviors are more than they appear… They’re Ayakashi Spirits, too.
According to them, you’ve been blessed with magical blood which the demon world will stop at nothing to get their hands on.
These men offer you protection… but only in exchange for something priceless. Are you ready to strike a forbidden deal with the Ayakashi?
