In the lobby of the Granada airport in southern Europe, 14-year-old Natsuki Tachibana was anxious. He had no other family left in this world. So now he is going to live with his aunt Alba, who is Spanish and seemed unfriendly at first. A new life begins in a strange country, with family he has never met before!

The beautiful cityscape, with its white stone walls casting deep shadows. The brightly colored tables, serving up gazpacho and tortillas. The cheerful people who gather at the Spanish-style shared-house "pisos" and bars.
