曽根崎 十郎

A top member of Q. Once he learned that LABO was conducting top secret BC research under the front of atomic power research, he swore to bring Rokumei City's deceit to light by any means necessary.
He is wanted as the principal offender for the Great Rokumei City Arson, but his whereabouts are unknown. Nevertheless, Q's membership is steadily growing, giving it influence over even the police and the hospitals.
People without BC abilities have long been uneasy about BC and Communicators, but for unknown reasons, Sonezaki's hatred for BC far outstrips that of average people.
Information regarding Q is thoroughly regulated within Rokumei City to the point that its existence is at most nothing more than common gossip among young people who are fond of the internet and are familiar with the name.

It is revealed in the Drama CD After Crime that Sonezaki is a Rank-S Level 6 Communicator who hates his abilities, and is the true founder of Q.
