Shintoism doesn’t play a major role in Domo ArigaDIE!!!, but its power certainly factors into the training of one of the major characters. I also spent considerable time listening to Shinto ceremony music while editing the book. Here’s a short educational video, long enough for you to reach Kami-sama. And for Kami-sama to reach you.
May the spirits of purification bless each and every one of us.
