41IC
According to Shinsei, The Day of Thunder was the time in the Kharmic cycle in which the champions of Yomi must face the Champion of Jigoku, to determine whether the next thousand years will be a Thousand Years of Peace or a Thousand Years of Darkness. Jigoku sought to spread its corruption through the Mortal Realm, while the powers of the Celestial Heavens sought to leave Ningen-do free to seek its own fate.
