Maseo Yamashiro (died April 2015) was one of the former mentors, former handlers, and an old friend of Oliver Queen. Maseo was also the husband of Tatsu Yamashiro, and the father of the late Akio Yamashiro. Sometime after Hong Kong, Maseo joined the League of Assassins, around the same time Sara Lance did. From then on, he came to be known as merely Sarab (Arabic: سراب; for Mirage), refusing to use his former name entirely.
