Ryūfuri (龍振り, literally Dragon Mode) is the hiden technique of the once feirce Ryouichi Clan formerly of Taiyougakure. The technique allows the user to attain the transformation of a dragon, but the user cannot become a dragon themselves as all dragon-based abilites must be accessed through various jutsu derived from the hiden technique. Maintaing the transformation requires a lot of chakra and the user remains transformed for too long, dire concequences could occur.
