Asura

The Asura (修羅 Shura) are the warrior caste of the Land of Asura. Asura receive a spartan upbringing, learning only how to fight and kill. Only 1% of Asuran boys reach adulthood.

Despite the fact that most Asura are completely heartless and brutal, there are some Asura who still have some kindness and humanity in them like Nagato, his men and Hyoh (before his corruption).

Initially they were depicted an unbeatable killers. A Nameless Asura was able to mortally wound Falco.

After Kaioh's death, the Asura were wiped out by the Hokuto army and the rebel villagers.
