- The story was originally emailed to select buyers of Waltz of Evil: The Deadly Sins of Evil Guidebook who inputted the password found on the inside of the light novel's advertisement strip at PHP's official website.
- Humorously, all four of the episodes make references to real world holidays or official events celebrated in certain parts of the globe.
