 As a younger man he also had sex with fellow prisoners of some prison.He can be fatally violent and has a shady past, which to date is unknown (although he has said to have been born in the steppe of Kazakhstan), even if the reader can guess he toured the world in his former criminal career, being a convict in many prisons and being sought after by yakuza (even if this could just be some idea his paranoid mind made up).He can be very arrogant with the weak, but turns into a prudent cowardice when faced with influent opponents.
