Yesterday, it was announced that Devon Aoki is set to play Katana in Arrow‘s third season, serving as a key influence in Oliver’s journey to becoming The Arrow. Now, we know who will be playing Queen’s other teacher in Hong Kong. According to TV Line, Real Steel actor Karl Yune is set to play Maseo Yamashiro, the husband of Katana (Tatsu Yamashiro). Like Katana, Maseo’s presence is described as a “major” recurring role. Throughout the series’ flashbacks, Maseo will grow to be a friend of Oliver’s who will help him to come closer to becoming the iconic superhero. Like his wife, Maseo is a skilled martial artist. Expect more casting news soon, as we get closer to the start of production and Season 3’s presence at Comic-Con. Arrow returns to The CW on October 8th.
