Rey Nanto Seiken (南斗聖拳)
There are 108 sects of Nanto Seiken. The six strongest Nanto masters are called the Nanto Roku Seiken, who correspond to the six stars in the Nanto Roku Sei constellation. In ancient times, these six masters each guarded one of six gates of the Emperor's palace.
After the nuclear war, Nanto Seiken was split into two camps, one seeking peace and one seeking power. When Yuda, one of the Nanto Roku Seiken, joined forces with Raoh (along with 27 subordinate sects), the fates of the Nanto Roku Seiken were cursed.
