Dorii and Guraa are twin archers serving under Oboro. They are talented archers and often lead archer groups in Hakuoro's army. There are few ways to tell them apart. For one, Dorii has purple eyes while Guraa's are blue. Also, the bottom part of Dorii's clothes are blue while with Guraa they are red.
