Gray has an easygoing, chatty, and sometimes aloof personality. He comes from a merchant family and therefore is knowledgeable of the world outside of Ram. He does not have much self-awareness, however, often barging into conversations and being unconscious of how his own words come off to other people. Gray asserts himself as the tacit "leader" of the villagers and is confident of his abilities. In battle, he adopts a gung-ho personality. Gray also non-maliciously makes fun of Alm at times.
