Natsu no Arashi!

During summer vacation, thirteen-year-old Yasaka stays at his grandfather’s house and meets Arashi, a sixteen-year-old girl working in a store. When a man claiming to act for Arashi’s family tries to take her back by force, Yasaka helps her escape, and she comes to stay at his grandfather’s home. Yasaka soon discovers that Arashi is no ordinary girl: she has mysterious powers. He also finds a sixty-year-old photograph of Arashi with another girl, Kaja. To everyone’s surprise, Kaja then appears—and, like Arashi, she has not changed in appearance since the photograph was taken.
