Flash Marker

Involvement in the Race for Revenge
Flash Marker (山中技師, Yamanaka-gishi, "Engineer Yamanaka") was a race car driver, and the mechanic responsible for the building and construction of the Melange, the same car used by Flash Marker Jr. in an attempt to kill everyone involved with the Three Roses Club for their murder of Flash Marker.

He was predicted to win the race at Danger Pass, and could have had an extremely promising and successful career due to his ability as a driver and the specs of his custom race car, which included a dual-tire design and an engine supercharger. He was an extremely skilled mechanic in every respect, and a racer of equal compare.

He was the father of Flash Marker Jr. and Lily Marker, two of the key characters in Race for Revenge. It's unknown what relationship he had with his children, but it can be assumed that he loved his children very much, as Flash Marker Jr. greatly cherishes the Melange and is hunting down the Three Roses Club in order to avenge his father. Because of the threat Flash posed to the Three Roses Club and their ability to win the race, Mr. Herring, Mr. Green and Mr. Black advised the three racers to kill Flash so that they would be able to win and get the 3x payout. This unfortunate greed is what set in motion the events of Race for Revenge.
