  Summary

  You get isekai-ed into supernatural after making a deal with Kyubey from puella magi madoka magica and are now forced to deal with the problems that being a magical girl in supernatural can cause (I've only watched season 1 so far so there may be some inaccuracies and also I put a OC into this but you can put yourself in the place of said OC)

  Summary

  This fanfic will be multi fandom, the main premise is that you're a therapist and these are your sessions with clients. Who are your clients? Traumatized characters that need therapy! Each character will have 5-10 sessions! (I haven't been to therapy in years so this is all just guessing)
