Heaven's Lost Property

Tomoki Sakurai's recurring childhood dreams of an angel have long left him with a sense of unease. His childhood friend Sohara Mitsuki, concerned for his well-being, seeks the expertise of Eishirou Sugata, an amateur enthusiast of the sky. Sugata's investigation into Tomoki's dreams leads him to believe a connection exists with the New World, a mysterious, unexplained aerial phenomenon. This theory prompts Sugata to form the New World Discovery Club, which eventually attracts the attention of an Angeloid who falls from the sky and declares Tomoki her master.
