Principles
Much if not all operations done within the dark side of Academy City is done in secret. This attribute has likely contributed to the unique subculture of the dark side of Academy City. An example of this unique culture is that those who have been sold into an organization can be hunted down by others if they attempt escape, as with the case with Nunotaba Shinobu. Another is when Tsuchimikado Motoharu's apparent "execution", where it is revealed that when agents of the dark side are convinced that someone is executed and dead, they will not go after that person again because they have convinced themselves as it is an etiquette of the dark side.
