@swagboythirtyeight I'm not disappointed, though. Definitely not what I expected (a tutorial on how to use the fusion calculator), but it's way more fun and creative than just a normal Rick roll. The fusion calculator creator definitely has a sense of humor and good taste in RU-vid videos.
I’ve actually got notes for a Carnival Phantasm style Persona, with this video having played a big part in inspiration. But while I have a bunch of amusing ideas for various scenarios, not sure I’m the best person for the job in this case.
