In a small city in northern Switzerland, near the woods, there's a nightclub called Sweet Poison. The place is ran by Theo, a dark faerie who's constantly surrounded by his four demon "friends". He has only met others from his kind twice, for the longest time he can remember but has never managed to keep in contact for more than a couple of weeks. But when another faerie named Arthur shows up for, supposedly, no apparent reason, Theo doesn't buy this for a second and nor does anyone, but nonetheless his curiosity gets piqued and he decides to learn more about this person's true intentions.
