Four Vigilantes’ Agreements

The Four Vigilantes' Agreements (咎追いの4つの協定) are a basic set of agreements and rules set out by the World Void Information Regulation Organization that each and every vigilante must adhere to.

Agreements
The agreements are as follows, all numbered one because they are all of the same importance:
 * 1. Obey instructions from the Librarium personnel.
 * 1. Provide information to the Librarium personnel.
 * 1. Do not harm civilians, or involve them in danger.
 * 1. Do not form organizations.

The last agreement is bent in such a way that one vigilante organization does exist; the Vigilantes Guild. However, the nature of the Guild is to spread useful info about bounties between vigilantes, so the Regulation Organization chooses to ignore it.
