Reido (Japanese: 霊道) is a indigenous religion in Akitsu, and also the most commonly practiced religion in Akitsu. It is also a philosophical and ethical tradition in Akitsu. It emphasizes living in harmony with the Rei, which according to Reido's beliefs is form of life that exists on a different layer of the world than the one humans live in but can nonetheless influence the world. Reido has since had a profound impact on Akitian culture. It's effects can still be seen in some aspects of Akitian society today. For example, the Reishi are still around and fairly well respected in Akitsu.
