- According to Ryohgo Narita's afterword, his original plan was to write a C Side and made the 2002 arc a trilogy. However, after certain circumstances arose, he was told to contain the story to two volumes or less; this resulted in him cutting about two hundred pages' worth of story and around three new characters. The cut content included a fight between Nile and Aging, which he says to look forward to in future volumes.
- The title of the volume is a reference to the band Black Sabbath.
