Arashi

appears only in the Naruto anime. He was the hope of the Fūma clan's shinobi who tried to rebuild their clan and Sasame Fuma's cousin. He and some others joined Orochimaru to gain the power to rebuild the Fūma clan.

Fuma Clan arc
Sasame mentions that before he joined Orochimaru, Arashi was the hope of the Fuma clan. He lost his mind after using the Casualty Puppet to absorb Jigumo Fuma and Kamikiri Fuma in order to increase his power. After absorbing his comrades, he was able to use the clan's most powerful jutsu, the Self-destruction Mandala, which uses a cage of chakra that constricts, crushing the opponent. It is unknown whether he died, but it is implied that he is killed when Orochimaru's lair caves in, as his feet are stuck to the ground by the remnants of his Casualty Puppet. He also notes that leaving the lair would result in his death.
