Nowaki "Fuushin"

Fuushin was born on a poverty-stricken island in the Land of Water. As a child, he was ostracised for his kekkei genkai and was blamed for being responsible for a typhoon that destroyed his village. He was sold to a businessman named Kusabi, and endured torture and starvation by his owner. At the Coliseum, he fought against Chino but was defeated when he fell victim to her Ketsuryuugan genjutsu, causing him to pass into the ownership of En Oyashiro. Fuushin was initially hostile towards Chino for winning against him but they became close friends after bonding over their mutual loneliness of being mistreated for their abilities and having no families. Fuushin also told Chino about his past, something he had never shared with anyone. Fuushin helped Chino, Karyuu, and the rest of the En's collected children escape from his compound. Chino returned to her ancestral Valley of Hell while Fuushin and the others formed the Lightning Group. Fuushin led their group, in their ongoing mission of stealing from criminals and distributing their plunder to the downtrodden, such as the people of the Bamboo Village. After the group was betrayed by Kirigakure, they asked for shelter in the Bamboo Village, who refused to harbour them in fear of retaliation. Unable to find help anywhere else, Fuushin was eventually able to find Chino in the Valley of Hell, where she took care of him during the year it took him for his injuries to heal. Once he was better, they formulated a plan to take revenge against Kiri and the other hidden villages for how they treated those with kekkei genkai.
