Keith is the oldest of the Gandor brothers (being somewhere in his late twenties or early thirties) and with his two younger brothers Berga and Luck inherited the Gandor mafia family from their father. Throughout the course of the anime he never speaks and is almost always seen with a deck of cards. He met his wife-to-be Kate sometime in the mid to late 1920s when she was still a silent film pianist. It is unclear in the anime if they are married or not, since there seems to be no wedding band on his ring finger. They are, however, married in the light novels.

In November of 1930 he and his brothers were at the Martillo Camorra gathering celebrating Firo's rise to camorrista where they unknowingly drank the Grand Panacea and became immortal.
