Jose has neck-length black hair and dark-colored eyes. He wears a black tank top.
When the Japanese Task Force raids the Mafia hideout in order to retrieve the Death Note, Mello and Soichiro Yagami are in a stand-off, with the former threatening to blow the whole base up with bombs and the latter threatening to write Mello's name in the Death Note.
Jose is in the same room, pretending to be dead. While Mello distracted Soichiro, Jose grabs a machine gun and opens fire, inflicting heavy injuries on Soichiro.
Jose tries to retrieve the Death Note but cannot release it from Soichiro's clutches. Other members of the Task Force then break in and shoot Jose dead.
