Tetsuro Ryuzaki (流座気哲郎 lit. Method of Feeling, Iron Law) is a shinobi with missing-nin status from Konohagakure. The only reason he has not been hunted is because he is seen as a possible ally, and a dangerous variable they may not wish to waste resources on. He has been noted as an S-class missing-nin, and one of the most dangerous tactical geniuses to date. Konoha believes that Ryuzaki has formed his own faction, later discovered to be called Hagemi. What he plans to do with his faction, and whether it will even participate in the World War, is yet to be seen.
