Roku

Roku is Dai's twin brother, they are both Hanyo. The way to tell him apart from Dai, is that Roku's hair is mostly green, and his outfit is a lighter shade of blue. Roku along with the other Hanyo children, except Ai, are unable to leave Horai Island due to the Mark of the Four War Gods which they possess.

Both Roku and his twin often annoy InuYasha by telling him he will be unable to defeat the Four War Gods, which usually recieves a wack on the head from InuYasha. Though they have annoyed the others at times.
