Hia is a remarkable member of the Offensive Classes IV Generation 1st of the F.M.A (Femistry Military Army). As a female soldier, she possesses exceptional skills and expertise in combat. Hia's primary weapon is a powerful Grenade launcher, which sets her apart from her peers. What makes her even more formidable is her ability to load various types of ammunition into the launcher. These include Graphite, Silicon, and Pyratite, each serving a unique purpose on the battlefield.

The Graphite ammunition is specifically designed to knock away the Crux Military, providing Hia with a tactical advantage. On the other hand, the Silicon ammunition allows her to lock onto runaway Crux Army targets, ensuring that they cannot escape her line of sight. Lastly, the Pyratite ammunition serves a dual purpose. Not only does it knock away the Crux Army, but it also burns them down, leaving no chance for their survival. However, due to a limitation in her targeting system, Hia is unable to target the Crux Air. Therefore, it is crucial for her to have protection from aerial attacks while also maintaining a strong defense against ground forces.
