Where did the creator of Sailormoon get ideas for all those daimons and the Senshis powers?
In this case, it is very easy to see the influence of Shintoism in the series. Many of the daimon (take the S-season for example) reside in certain objects, like a cat puzzle, or a pair of glass slippers. When called upon by the Death Busters, the evil kami shows itself. When Sailormoon destroys them, you can see the spirit dissipating into the atmosphere, having been banished from its residence. As to the Senshi’s powers, not all of them are Shinto priestesses, so how do they get their powers? Like Rei, they were created with the ability to draw power and energy from the earth. For example: Sailorneptune can summon power from the oceans, and Sailorjupiter can summon power from thunder and trees.
