Chui (Sub-lieutenant) is the third commissioned officer rank in the Star Army of Yamatai after Shoi and before Taii and is the second officer non-training rank. The rank pin consists of a white enamel triangle with the officer's fleet logo nestled in the center of a bronze colored metallic heart. Chui are too low ranked to command most ships; they typically serve as bridge officers or commanders of smaller ships.
