Daimon always seems to have a very serious expression, and grunts a lot. However, he has a very warm heart, as he always takes his time to coexist with nature and immerse himself there. He also likes to teach youngsters about Judo in his free time. He can be patient, an adviser and a mediator. He wasn't very popular with ladies due to his large and "scary looking" stature—a fact that he lamented for many years—until he was fortunate enough to meet the woman who would later become his wife.
