"Spirit Silk" 

These people only had to use spirit glasses to see spirits and help shamans to make contracts with these spirits. 

Thanks to the emergence of a new profession, many people who awakened charm ability users were trained early on to influence beasts, plants and even spirits other than charming fellow humans and non-human races. 

Those who were talented in charming beasts and monsters had their own division in the guild. 

Those who could charm spirits were rare, but they were highly sought after by shamans who wanted to tame many beast spirits or even plant spirits. 

Now, not only the beast tamer and the monster tamer guild who had a connection with the irregular tamer guild. Even the shaman guild became a strong ally of the irregular tamer guild.
