Asahi Shiina (椎名 旭 Shiina Asahi) is one of the main characters in the movie High☆Speed！－Free! Starting Days－ and Free!'s third season, Free!-Dive to the Future-. He is also a minor character in the light novel High☆Speed！. He is currently a student at Hidaka University where he is a member of the swim club alongside Haruka Nanase and Seijuro Mikoshiba.
Asahi is a slightly taller than average young man with a toned figure, messy red hair and pinkish eyes.
Asahi possesses a bright personality and a vibrant spirit. He is articulate and energetic in both words and actions, always ready to push his luck, a fact that often makes him quite comical. In High☆Speed！－Free! Starting Days－ he is determined to recruit Makoto Tachibana and Haruka Nanase into the junior high school swimming club after learning that they used to be part of their community's swimming club while in elementary school. He is also the one who goads Ikuya Kirishima into joining despite his negativity.
He enjoys competition and works hard to achieve success. While seeking books about self-improvement in the Iwatobi library, he inadvertently meets Rei Ryugazaki who offers advice. When facing challenges in sport, Asahi repeats saying "I am a genius" out loud to himself as motivation. This continues into university where Ikuya teases him about it.
Asahi always wanted to become the captain of the swimming club and in Free!-Timeless Medley- the Promise, he is shown to be the Captain of Kazami High School's Swim Club.
