An earthling who knows the entire plot of "The End of Ten Days" is reborn as a "human mouse" at the bottom of the Land of Ends. He must use his foresight and loopholes in the rules to climb from the zodiac to the mythical beast step by step in the Shura field where thousands of people are competing for ten years of reincarnation, and finally overturn the eternal cage carefully designed by Tianlong. The settings of this derivative work are partly inherited from Toka, but there are also some original settings created by the author.
