Troiatt Firandin Gabanest

Troiatte is a playful and whimsical military artists from Grendan and one of the 12 Heavens Blades. Admittedly he can't be rude to ladies, be of any age. In battle he manipulates a huge ball of light that shoots out multiple heat rays. Not much is known of him other than he trains Cauntia and friends with another Heavens Blade, Ruimei. He often calls the later on the nickname of "Danna". Troiatt has only a brief appearance in the anime and doesn't have a huge role in the original novels either. The Chrome Shelled Regios artbook shows her name to be written as Troiatt.
