V3:Genma
From Slavemaker Wiki
Genma Saotome is one of the Assistants in the game. A Slave Maker with odd techniques, often involving humiliation. He is a trained martial artist, but a bit cowardly. He can be used to train any girl and increases her Maximum Obedience by 10%.
During Tentacle and other hostile encounters, he will flee, so you will not see the usual "assistant getting raped" image.
