The faction was cut from Global Offensive before official release, but a description of this faction still exists in the game files:
"These Clan-less criminals claim no affiliation beyond their own ad-hoc gangs. Spurning tradition, they flaunt their body art indiscriminately and accept any job regardless of its impact on the civilian populous."
Another Japanese Terrorist faction was originally planned, based on the Aum Shinrikyo cult. Logically, they should have been in Truth in Chaos, but the faction was dropped and the standard Akunin terrorists take their place.
Akunin means “悪人” in Japanese kanji, which literally translates to “evil person”.
