Mystery: Yamato Torus

A Spell Card of Kanako Yasaka from the world of iron and steam. She deploys an ancient ring in this attack. There are two main types of ring-shaped objects used in Shintoism―chinowa, great rings of cogon grass that people pass through as part of a purification ritual, and shimenawa, thick ropes of rice straw or hemp. They both share the same religious significance. They are generally used to create boundaries or barriers with a clear inside and outside. However, they can also be used to erase boundaries because connecting the start and end of a rope together forms a ring that symbolizes eternity. In the far west, this idea is represented by the ouroboros, a symbol depicting a snake eating its own tail. Eternity is immortality, but it is also a near-inescapable prison. That is why shimenawa are used to tie up and restrain gods.
