Bushi are usually forming a band, Bushidan to be able to fight with Oni more efficiently.
Known Bushidan Edit
A Bushi 's duty is to kill the Oni. But this can be led back to a prophecy, called Unity Under Heaven (Tenka Touitsu). According to that once every Oni is annihilated the divided states of Hi no Moto can be one again. And when the strongest Bushi defeats the strongest Kishin the sacred treasures will return and will be the new ruler of Hi no Moto.
