Fūshin (風心, Fūshin) was the head of the Lightning Group.
Fūshin is the leader of the Lighting Group, a group who steals money from bad people and gives it to those in need. In the past he and his team helped the people of the Bamboo Village. After the group was supposedly betrayed by Kirigakure, they asked for shelter in the Bamboo Village, who refused to harbour them in fear of retaliation.
Fūshin is a man with long green hair and yellow eyes. He is seen wearing a dark hooded cloak and has a scar under his left eye.
Sasuke Shinden: Book of Sunrise
Sasuke goes to the Coliseum with Orochimaru to gain information on Fushin and the Lightning Group because he suspects Fushin is involved in the disappearance of missing shinobi from Konoha, Kumogakure and Kirigakure. Although he learns the background of Fushin and his group, Sasuke never meets Fushin because his whereabouts are unknown and later finds out Fushin is not responsible for the disappearances.
In the anime, however, Fushin is revealed to have been helping Chino create exploding humans in order to find and kill Sasuke. To not draw suspicion, Fushin alters his appearance and uses the alias Nowaki.
