Robin furrowed his eyebrows... The situation on Nihari was complicated, extremely complicated.
There are dozens of tribes that specialize in specific offensive divine tattoos and occupy large areas of land and each one is a stronger and controls a larger area than the Black Sun kingdom
And on top of that, there are 12 tribes that have the 4th degree of Body Strengthening Divine Tattoo that reaches the strength of emperors between levels 40~50, and They also have offensive divine tattoos of all paths
Not only that.. there are a large number of other races that live on these lands.
