A third name that Japanese GPW fans use is BONDAGE M@STER (ボンデージマスター), which is both related to his BDSM reputation and his line "...dungeon master...", which was also found in 101 Rent Boys and to the Japanese media franchise The iDOLM@STER. It also refers to the House of Detention film, and is shortened to ボンマス (BONMAS).
