Guraa

Dorry and Guraa are twin archers serving under Oboro. There are several ways to tell them apart: Dorry has purple eyes while Guraa's are blue, and the bottom part of their matching garments is blue on Dorry and red on Guraa.

Spoiler

Their gender is difficult to ascertain, even by other characters. In the game, Oboro and the twins themselves state that they are male.
