Gieve has shoulder-length blonde hair and matching yellow eyes. He wears a white-and-black military-looking uniform with red stripes around the edges and a black cape/cloak.
Gieve is known to be arrogant and hot headed, but is also a cold and careful fighter. As shown in his flashbacks, he used to be kind and passionate. When he realizes he was a Trion Warrior all along and his memories were implanted, he starts losing his mind, becoming insane.
Due to the implanted memories, Gieve despises Xeno, and when Xeno reveals he doesn't know him, he assumes that Xeno forgot about him. He becomes obsessed with Xeno, to the point of losing his mind.
Gieve worships Lilith, calling her Ergates' beloved "goddess of war". He is willing to do whatever it takes in order to take her back to Ergates.
As shown in his flashbacks, he was fond of Lamia. He is hinted to have feelings for her, and doesn't mind the fact she probably considered himself a failure.
