The CW's Arrow has just added a new character from the DC Comics world.
Devon Aoki, sister of world-famous DJ Steve Aoki, will play Tatsu Yamashiro, aka Katana, in a recurring guest role starting with the show's upcoming third season.
Tatsu is a sword-wielding martial arts expert. Her nickname, Katana, is derived from the name of her sword. Appearing during flashbacks, she will be an instrumental mentor who helps Arrow become the man he is in the present day.
Aoki's credits include the films Sin City, 2 Fast 2 Furious and D.E.B.S. Deadline first reported Aoki's casting.
