The owner of Enseignes du Roy, Oscar, returns from his business trip in Japan and surprises his grandson Claude with the goods he has brought from Japan. However, among the genuine items Oscar has brought along with him is a girl wearing an unusual and exquisite clothing... a little girl with an innocent charm.

Claude immediately shows his disappointment about his grandfather's excessive amounts of souvenirs, especially at a time when the outflow of Japanese merchandise into the European market has made things troublesome for their iron crafts shop. Nonetheless, Oscar stays assured that their business will continue to bloom, especially with the Nagasaki-born girl in their care.

Oscar introduces the Japanese girl as Yune, a girl known for being a poster girl in her home, and Claude experiences culture shock as he finds himself unable to determine the right reaction to Yune's actions.
