Kip. 487: The Ketsuryuugan
Sasuke and Fuushin fight, with Fuushin's Typhoon Release overpowering Sasuke's Susanoo. Sasuke wins by jumping in the hole of the funnel and hitting Fuushin. However, Sasuke's attempt to get information fails and Fuushin escapes. Traveling to Hell Valley, Sasuke finds Chino waiting for him and she reveals herself as the sole survivor of her clan. In a backstory, Chino was kidnapped by Oyashiro when she was too young to remember her parents and discovered her Ketsurygan through training. At the Coliseum, she fought and won against Fuushin, whom she befriended due to their loneliness of being ostracized. After finding out about her clan, Chino escaped with Fuushin and a few others, becoming the Lightning Group to help the Bamboo village. However they came into conflict with the Hidden Mist village, which caused the Bamboo villagers to betray them. Two of their comrades died and Karyu left, and Chino and Fuushin arrived at Hell Valley to find her clan was destroyed. Two Hidden Mist shinobi attacked them but were turned into Exploding Humans by Chino, who vowed revenge. (Source: Wikipedia) Sasuke Shinden: Book of Sunrise arc: (4/5)
