Bimonia is one of the last Birdlings alive on this earth. The Birdlings see humans as sworn enemies, and Bimonia has been taught to kill on sight.

One day, Bimonia meets Tayo, a human child hunting in the forest. Bimonia fails to kill Tayo, and they instead become friends. Mother will be furious if she finds out, or worse, this relationship may cause tension between the two races to erupt.

The Last Birdling explores Bimonia and Tayo's fight for their friendship as the world threatens to tear them apart.
