Every mirage is actually a gateway to another world. On the other side lies a world called Mirage, home to another powerful race, the Mirage Clan!
One day, the gates to the other world opened, and an army of savage, bloodthirsty monsters poured through. The human world became hell!
On a battlefield strewn with corpses, a young man moves with dazzling agility, constantly reaping the lives of his enemies.
His name is Lu Yu, a man whom King Yama refused to let through the gates!
You think spending money makes you great? I'll spend my life force!
