"Spider Web-like Connection"

The members who had families to support or children were all excited when they finally got their irregular tamer business license. 

With the money they got, they could easily support their children and family, unlike when they had to struggle hard in the past. 

The guild didn't need to worry about the stream of customers either. 

The beast tamer could indeed help others to contract beasts, but only the irregular tamer guild could help someone contract monsters. 

Plus, the irregular tamer could make the beasts work for them without using any contracts. 

With this, the irregular guild also opened vehicle service using beasts and monsters. 

Of course, all the beasts and monsters they captured were those who were hostile to humans and weren't liked by their peers either 

In other words, they're criminals.
