Sakura Mau Otome no Rondo

Aoi and his imouto Yuri have lived overseas since they were small, moving from place to place while following their father’s work. One day, it would decided that his father’s new job would be in a southern country where the sun’s rays beats down hard. However, since their mother thought it would not be good for the weak Yuri to come with them, the two of them were sent back to Japan.
