It's the year 2173. A few weeks ago, more precisely, since 26.05.2173, in all major cities of our world there is only one theme on the All-Net (An advanced version of our Internet):Aestral Worlds online, the first fully functional Float-System using online game.As part of the promotional campaign of Zestro-Electronics, the developer of the Float-System and Aestral raffled 1000 beta access codes among the 13 million preorders. This caused great longing in almost all of the future players.One of the winners was Ryouta Kuwakabe, a 16 years old student from ""Seishou Academy for Technical Arts"" in Tokyo who doesn't even know about it.
