Serge Echigo is the man who helped craft the android regulation law in Judo, which states that no android will be permitted within the city. At first, he wanted to create a monolopy of the android business. However, finding that he could not do this, he began to stage incidents that showed that androids were dangerous. The final incident, which forced the government to craft the law, was the murder of Daisuke and Shun's father. In effect, this incident killed two birds with one stone as Marius was also lobbying to dispose of the anti-immigration law that Echigo supported.
