DMO, which is tomb robbing online [I'm sorry for the name, please don't complain...]
Holographic online game settings.
The game background is based on the game settings of SAO [Sword Art Online], so I guess the previous description of the game background will look a bit familiar = =. But I've tried my best to modify it.
Then don't ask me questions like whether my brother is Kirito or whether Wu Xie is Asuna.
No.
I just used the background of SAO to tell the story of Brother and Wu Xie. They are themselves, and no one else is.
