He is the captain of the Kamakura-Kita High School track club and Hitomi Kanzaki's crush.

As a national-record-holding sprinter and all-around friendly person, Amano gained popularity among his peers at Kamakura-Kita High School. He plays no small role in Hitomi's decision to join the track club, and her crush on him manifests itself in front of Yukari Uchida (Hitomi's best friend) as well as Amano himself. However, Hitomi discovers Amano is to leave the country to study abroad, and decides to ask him for her first kiss if she can sprint 100 meters in 13 seconds. The surprising appearance of a dragon and a prince causes Amano to try to grab Hitomi but she is gone and Amano is drawn into the ensuing drama.
