Does Rei worship that bonfire thing?
The straw/rope cord twisted to the left with ritually folded white paper tied to it denotes an object’s religious significance. This cord is tied around objects possessing ancient spirits which deserve respect, such as trees over 100 years old, or placed around a sacred fire. The white papers are prayers addressed to the kami of the object, showing respect for it. Shinto Shrines (Jinja) were set up around these highly-respected kami, just as Rei’s shrine, the Hikawa Jinja, was set up around a very important fire kami. Rei draws her power and energy as a Sailor Senshi from the spirit of the fire. Occasionally, she also combines her talents as a Shinto priestess (technically a miko) with her fire-soul to make a very powerful attack.
