Ao Ashi (アオアシ) is a Japanese manga series written and illustrated by Yūgo Kobayashi and based on a concept by Naohiko Ueno. It has been serialized in Shogakukan’s seinen manga magazine Weekly Big Comic Spirits since January 2015. The series involves youth football player Ashito Aoi and his journey and experiences in the Tokyo Esperion youth academy. An anime television series adaptation by Production I.G. aired from April to September 2022.

In a quiet rural town, the spotlight of a local junior high school football team rests on one player: Ashito Aoi. Known for his unpredictable moves and self-centered playing style, Ashito is the sole powerhouse pushing his team through an important high school preliminary tournament. However, their win streak is short-lived—an opponent causes Ashito to lose his temper and act violently, resulting in his removal from the rest of the game.

Without their star player, the team is quickly eliminated from the tournament. Just as he believes all hope is lost, Ashito is approached by a youth team coach named Tatsuya Fukuda who senses potential in him, and Fukuda invites him for tryouts in Tokyo. In an unfamiliar setting surrounded by talent, Ashito must bring out the best of his ability to prove himself and secure what could be a life-changing career.
