Kamoana is a very lively girl, growing up with the people of the Haria Village. She would often go out to play outside the borders when possible. During the story, Kamoana encounters Velvet and the party, where she meets Laphicet and becomes friends with him. This relieves Kamoana as she does not have many friends around her same age group. Kamoana is said to be cheerful but can also be very childish, which she reflects on later and claims she wants to be a better person.

As a Therion, Kamoana is scared, often crying because of her transition between her human appearance and that of her daemon's. At first, she referred to herself as scary and ugly, but with comfort from many of the party members, especially Laphicet and Eleanor, she starts to accept herself and move on with life. From there on, Kamoana regains her former cheerful personality.
