Mushi-shi is a very atmospheric anime with great story telling and fascinating philosophy behind it. Mushi-shi is more calming then most phycological anime, as the show does not want to scare watchers, but to bring them on a spiritual journey. There are many great episodes following our protagonist Ginko. Some examples are Raindrops and Rainbows, One-Night Bridge, Cotton Changeling, Shrine in the Sea and many more.
Obviously specific episodes will need to be mentioned. However, you mentioned that Mushi-shi is "more calming then most physiological anime". It would be a good idea to compare these specific episodes to other animes in order to reflect Mushi-shi's uniqueness. – Ryan Errington5 years ago
