This is not a simple game. The essence here is actually the same as the real world we have certified. We can no longer tell which is reality and which is illusion... Therefore, we may lose ourselves and sink into this game...

SAO (Sword Art Online) - a once popular virtual game that treated human lives as a game, leading to the death of tens of millions of people. Many game companies that produce virtual games have also been affected by this, and virtual games have disappeared into the depths of people's memories.
Now, another virtual game called "BDS (Bi Dance Spirit)" has returned to people's attention. As soon as this game was released, people were crazy about buying it, with the same madness and obsession as when they were buying SAO.
