Six children from five countries including the UK, China and the US come to the hometown of Maruko (voiced by Tarako) Shimizu City. Andrea (voiced by Taishi Nakagawa) from Italy temporarily stays at Maruko's home. Maruko and his friends attend school with foreign children and travel to Osaka and Kyoto on weekends. At first, Maruko was troubled by Andrea's enthusiasm, but after learning the reason for his visit to Japan, she began to get along with him. The two of them went to the temple fair together and made a wish to "hope to meet again." However, these happy days are about to pass, and they will usher in the time of separation.
