Claude drops by Asuka's place, only to find out that she and Maria have gone shopping. Claude reads a note left by Asuka, which states that the Yakuza's police informant has said to them that one of their drivers is an undercover cop. She then tasks Claude to kill him.
He then heads to Kenji's Casino in Torrington. Once there, the driver is seen hopping onto his car. Claude then follows the car and tries to damage it enough to make him pull out of his car, all while having a high wanted level. Once he has bailed, Claude quickly kills him.
Maria and I have gone shopping. Our source in the police has informed us that one of our drivers is a strangely animated undercover cop! He's more or less useless out of his car, so we've tagged it with a tracer. Make him bleed!
The driver, along with his name and outfit, is a reference (and a mockery) of Tanner, the protagonist of the Driver video game series. He is mentioned by Asuka as being "useless outside of his car", referencing the lack of on-foot abilities in Driver 2. Tanner is even given a female running animation, making fun of the strange way Tanner moves in Driver 2.
Damaging or destroying Tanner's Esperanto before entering the blue marker will alert him, failing the mission.
