Happy Halloween everyone! While this may not be the spookiest mashup (I probably could've saved the Mephiles combo for it but oh well lol), this is still a great combo in my eyes and I just happened to finish it today. I do have a potential project in the works, though if it comes through I think it'd be released on a certain day in December. Enjoy!
