Ever since he was a child, Tomoki Sakurai has always woke up with tears after a dream of an angel. His childhood friend Sohara Mitsuki worries about this and decides to seek the help of Eishirou Sugata, an eccentric sky maniac. He concludes that Tomoki’s dream is undoubtedly connected to what is known as the New World, a floating anomaly that scientists have failed to understand.
