Who knows the name of the comma-shaped ornament worn by the witch on the silver soul?

It's called hook jade, which is a very traditional ornament in Japan. The blood volume of the Three Kingdoms Kill is represented by Gouyu.

Pronunciation of hook: MANA, where MA is pronounced as having a good reputation, but not competing with the world, and NA means luck and God's blessing. Taken together, it can be considered great and glorious.

Generally speaking, people who are engaged in Shinto and divination-related activities, as well as people who have a certain position in ancient times, will wear or own their own gouyu, and witch MM also likes this kind of thing.

Ancient gouyu is a very precious thing, either because of religious relations or because the output of high-quality jade in ancient Japan is very small. According to historical records, Empress Jimiko paid two gouyu (while the pearl was 5,000, which shows the preciousness of gouyu). Gouyu is not difficult to get now.

In particular, Gouyu is the 1 of Japan's "three artifacts", and the emperor inherited something from the gods.
