Y462

Y462 (real name unknown) is the member of the Mafia who made the trade for the Death Note with Soichiro in exchange for Sayu. He killed Miller as a test, and then Zakk Irius and Kyle Block, the plane's captain, to eliminate all links to the kidnapping. Ross falsely promised Y462 that if he succeeds with this exchange, then Ross will forget about Y462's past failures. After Y462 placed the Death Note in a missile and took off separately on a helicopter, Jack detonated the aircraft to kill Y462 to eliminate the final link to the kidnapping.
