Weapon: Ala-Gladius (Bastard sword)

The male protagonist in Prism Ark. Hyaweh enrolled in the knight school in Windland and it was during that time that he met most of the other characters. He is a typical laid-back student, both in the game and in the anime, doing things like skipping class and forgetting textbooks. He appears to dislike fighting with others, always trying to escape if it is an option. He will, however, step up to protect others. He seems to have fell from the sky as an infant along with the sword, Ala-Gladius. His actual origins are never made clear, but he is implied to be from the Ark, a high-tech spaceship orbiting the Prism Ark world.

In both the game and the anime, Hyaweh's sword is shown to have the power to destroy the Angels. However, the actual power it manifests differs between the game and the anime. In the game, the sword merely prevents Angels from moving when its power awakens. In the anime series, the sword is used to physically attack Angels, and in the last episode Hyaweh awakens the Ala-Gladius together with Priecia, which calls down energy from a geosynchronic satellite, which transforms the two into a supernatural being which can rival the Angels.
