Driver (Kojin Taxi)

This unnamed taxi driver is the serial kidnapper and rapist who is the protagonist of the five-episode hentai anime Kojin Taxi (also known as Sex Taxi).

Physical appearance
He has brown and blue eyes and wears a golden earring on his left ear. He is mostly seen wearing his cab suit, including a dark green tie and a cap, or naked. His taxi is remarkably bright and magenta-colored, number 12-59.

Personality
He has a strong sadistic nature and frequently exhibits an evil grim and says sarcastic comments. He is totally merciless, not appearing to show any trait of remorse for the hideous acts he commits. However, in the last episode, he acknowledges that he is not a good person and should not be seen as such.

Modus operandi
In a process he calls "hunting", the driver learns about the lives of his potential victims until he gets three pieces of evidence to blackmail them. Leaving them with no choice, he forces the girls to become part of his personal "collection".

He takes advantage of the fact that people who ride a taxi never suspect that the driver pays attention to what they are saying or doing. He, however, is very attentive to his clients and has hidden equipment in the car that he uses to record their phone conversations. He also stalks them into their private lives to, when given the opportunity, photograph or record them in compromising behavior with his high-quality Pekonax digital camera.

He seems to move regularly from town to town in order to start new seasons of "hunting". In the town shown in the anime, he used an abandoned school that was going to be demolished soon as the kidnapping site, although it is possible that he used other places in previous towns.

Victims
He kidnaps and rapes a total of eleven women in the anime. He also "shares" his victims with other men at some points.
