Thirteen Hells of Reincarnation

Gray fog descended, and thirteen people were trapped in a cage. The twelve masks are all the remains of my previous life. They are immortal and can be resurrected indefinitely. Only I will die completely when I die. Rules force fighting, and outsiders are reduced to backing up. Every death game is a stripping away of humanity. Every time the mask is broken, it is the completion of the self. When the twelve obsessions return, the thirteen souls become one. This cage, this fate, this eternal mystery—— It will all be ended by me, Xiao Lan, with my own hands. But is it true?
