In a small Japanese town, Tsubasa, an ordinary third-grader who says he wants to be a footballer only because everyone else does, finds a friend in Gyotaro Hoshi. Gyotaro is strange, funny and fearless. He claims to know what the top of Mount Fuji looks like, carries a piece of meteorite and brushes his teeth for half an hour at the school tap. The two become inseparable, walking home past the secret tree and through the tunnel where you must walk weirdly or die. But Gyotaro keeps getting into trouble, and Tsubasa’s mother tells him to stay away.

One day, Tsubasa makes a small, quiet choice. Following the two boys from primary school through high school and into their twenties, Kohei Kadowaki’s film watches that choice ripple across the years, as one boy’s life moves on and the other’s stalls. Drawn by hand, it catches all the restless movements of childhood with rare precision and moves freely between ages and points of view. Funny, tender and painfully honest, it is a film about friendship and cruelty, and about the one thing an ordinary boy will spend the rest of his life trying to forget.
