Although he does not fight, his physical abilities are top-class in the series, easily lifting the petrified Yuzuriha with his superhuman strength, and boasting inexhaustible stamina, such as stating that he could cover a distance of 80 kilometers in five hours because it's "two full marathons."

He lived in the Tsukasa Empire as a spy and hostage while supporting Yuzuriha, but later joined the Kingdom of Science. When agriculture began, he was appointed as the leader. He was also entrusted with various physical tasks, such as mining in the mines. He boarded the science ship Perseus as the person in charge of physical labor. After everything ended, he married Yuzuriha and established a fashion company, becoming an employee in charge of physical labor.
