Natsu no Arashi! - S02

The summer of a man's boyhood memories goes on. Still caught between childhood and adulthood, he has formed a bond with the ghost of a young woman from the World War 2 era. She, along with the ghosts of other young women from that time, keeps having adventures with their linked partners, learning more about one another and traveling through time thanks to their supernatural connection. While he struggles to make his crush on her real, his friend, a girl his age who pretends to be a boy, also wants his attention.
