It has been four years since the incident that has come to be known as the Twilight. Many of those who witnessed it no longer come to "The World." It is a different place. A safer place. Shugo and his twin sister Rena are two of the newest players to join "The World." And they've won a very special prize in a contest - they get to use the character likenesses of the legendary Kite and Black Rose. Such a prize is very rare indeed, and it makes them the center of a lot of attention. The pair will encounter friends and allies, but it soon becomes very clear that they are not ordinary players. Unusual things keep happening around them, but they're too busy having fun to really worry. It's probably nothing. Probably.
