Ittô Juni (一准尉; Warrant Officer First Class; typically referred to as Chief Warrant Officer) is the highest of three warrant officer ranks in the Star Army of Yamatai. The rank below is Nitô Juni. Warrant officers are experts in their specialty. In casual or combat situations is acceptable to just say “Juni” rather than the full rank title.
The rank pin consists of a blue enamel triangle with the officer's fleet logo nestled in the center of a golden metallic circle.
