Blue Flag (manga)

Blue Flag (Japanese: 青のフラッグ, Hepburn: Ao no Furaggu) is a Japanese manga series written and illustrated by Kaito, the creator of Cross Manage. It was serialized digitally on Shōnen Jump+ from February 2017 to April 2020, and publisher Shueisha later collected the chapters in eight tankōbon volumes. A slice-of-life manga set in a high school, Blue Flag tells the story of a group of friends who must navigate personal difficulties, societal expectations, and their feelings for and about each other.

Blue Flag has been well received by readers and critics, who have praised its art style, characters, and handling of LGBTQ themes. In North America, an English translation was licensed and published by Viz Media. It has also been translated into Chinese, French, German, Italian, Polish, Portuguese, and Spanish.
