Dark-fallen swords usually experience damage from people and eventually devour the owner.
In order to survive without being cut into pieces, they began to accept new judges
Here you can see all kinds of weird judges
For example
From Onmyoji: The Killing Matt Judger
A female ghost judge who likes to crawl on the ground
The concubine's judge from the palace drama
Cute loli from the madhouse
A bad judge from the world of cultivation
…
Various judges for you to choose from
PS: I've seen a lot of various colleague settings and I'll give you the whole life
Concept: This world is really full of strange things
