Akuno-P was one of the many obscure producers until he released "Aku no Meshitsukai", which subsequently became a big hit.

The series are connected, crossing over in various song and forming an intricate storyline known as The Evillious Chronicles. Due to the loose or ambiguous link between some songs and series, added to the fact that this storyline is continuously expanding and not all the songs have been revealed yet, slight confusion among the fans about how they are related is common.
