グラァ

Dorii and Guraa are twin archers serving under Oboro. There are several ways to tell them apart: Dorii has purple eyes while Guraa's are blue, and the bottom part of Dorii's clothes is blue while with Guraa they are red.[From Wikipedia]Their gender is difficult to ascertain, even by other characters. In the game, Oboro and the twins themselves state that they are male.
