Y462 is an unnamed member of the Mafia.
Y462 has a short crop of blond hair and is seen wearing a white suit with a yellow tie. He wears a blue dress shirt underneath his suit.
Y462 makes the trade for the Death Note with Soichiro Yagami in exchange for Sayu. He kills Miller as a test to see if the Death Note is, in fact, real, as well as Zakk Irius and Kyle Block, the plane's captain, in order to eliminate all links to the kidnapping.
Rod Ross falsely promises Y462 that if he succeeds with this exchange, then Ross will forget about Y462's past failures. After Y462 places the Death Note in a missile and takes off separately on a helicopter, Jack Neylon detonates the aircraft to kill Y462 to eliminate the final link to the kidnapping.
