Інуй Джюдзо

An Over-Extended working as a private investigator dealing with cases related to the Extended. Due to stylizing himself after a stereotypical hard-boiled detective, he maintains a serious and collected demeanor and encourages others to solve their own problems, his motto being "Wipe your own ass". However, he often struggles to hide his love for cheesy one-liners, pretty women, and kitschy romance stories, the latter two often making him struggle to stay calm.

During the war, he was part of a group consisting of Over-Extended from the Gun Slave Unit series, designated "Number 13". At one point, he was ordered to dispose of the rest of his unit, gaining the moniker "The Brother Killer, Verrat Dreizehn" or "Traitor Thirteen".
