Taking place directly after the events of the first Kita He: Diamond Dust, the sequel ships the protagonist to Hokkaido for a continuation of potential love. Over the period of seven summer days, players interact and commingle with the girls in order to get to know them better. Perhaps if one girl is more appealing than the others, true love and marriage will blossom. A new conversation system is introduced in DD+ called the Communication Break System where conversations may go off in tangents (as they do in real-life) if the player interjects when keywords are spoken by the girl. New conversations may then lead to alternate events which draw the couple closer together or at least more congenial towards each other. Like previous Kita He games, photographs of actual locations in Hokkaido are used for the backgrounds as the protagonist roams the city in search of true love. [from NCSX]
