Susano Azume (スサノオアZユム, Susanō Azyumu) is a missing-nin from Numashi Village of Jonin level who currently travels the world, seariching for the meaning in his life. Raised in the Hidden Swamp Village, Susano never became an ninja of the village, but left to pursue his own dreams and goals. Susano is mostly known for his distinctive blue hair. It is later revealed to him that a demon called Raio is currently imprisoned in his scarf. Occasionally, Raou's power has been known to leak into Susano's body, causing violent outbursts of chakra.
