Gaius is a friendly yet level-headed guy, able to discern the true nature of things without prejudice. He is grateful to the wind and Aidios for the people he has been able to meet and the experiences that have come across his path. His personality is without any sense of discrimination, leading him to be heavily relied on by the members of Class VII. Within the group, he frequently acts as the voice of reason. He is a very devout follower of the Septian Church and Aidios as a result of his mentor's, Barkhorn, influence.
