Joe is an extremely upbeat, excitable, considerate, and loyal person. He is easily embarrassed when others misinterpret him and is sensitive to how people perceive his appearance. Like Sara, Joe puts in all his efforts to help the group succeed in the puzzles. He consistently convinces the group to believe in Sara and her abilities and generally places most of his trust to her. Though he is described as gaudy by Reko and has a small habit of saying the wrong things at the wrong time, Joe is genuinely kind-hearted and sensitive to others' feelings.
