Hiyori is light skinned with blue eyes and white hair that flows out either side of his head.
His casual clothes are grey boots, grey dungarees and a white jumper with yellow stripes. He also wears a grey hat.
He is first seen in episode 1 when he asked Norika if she had problems because it was unusual. He started looking down with some of the team about not being able to win a match at the Football Frontier and the team's disbandment. He was with Goujin when he was training for a hissatsu technique and he told him that 'Fire Lemonade' was Fire Tornado. With Norika and Hiro, he was at the edge of a cliff, watching the sunset and talking about leaving Inakunijima. He said that they might have a shot against the mainland teams. When the team got to Raimon, he thought the original Raimon team would play with them but everybody else knew that the team had been 'paused indefinitely'.
During the match between Inakuni Raimon and Teikoku Gakuen, Hiyori was one of the players who decided to move up after seeing Teikoku's plays. When Sakuma Jirou used Koutei Penguin 2gou with Fudou Akio and Jimon Daiki in the second half, he, Hattori Hanta and Okuiri Hiro used Gravity Cage to successfully stop Koutei Penguin 2gou. In the end, Inakuni Raimon was able to win from Teikoku Gakuen with 4-3.
