Ilya Volgof was a member of TKBM's Team 13 under the command of Seo Joo-Heon. He is the most skilled of the Aftermath Clean-up Crew which specializes in modifying memories and disbanding tomb raiding teams. He is currently working for Kwon Hyuk Soo after quitting his job as a talented exorcism priest at the Vatican in Italy and losing his girlfriend Galina to find a way to revive her without realizing that the Vatican executed her and used her as a sacrifice for Un-Known. After he regained his memories, he betrayed Kwon Hyuk Soo but refused to rejoin the team which resulted in him being beaten up and forced to sign Seo Joo-Heon's contract.
