Gatsu

is a bounty hunter in the Land of Stone.

Bounty Hunter Arc
Gatsu tried to get Sazanami after he was injured by Gosunkugi but failed because Naruto and the others were protecting him. Upon leaving, he accidentally drops a wanted poster. Strangely, they note that the person on the poster's name is Tokichi and has the same bird mark that Sazanami has.

Later Gatsu catches up and catches Sazanami and Gosunkugi. In the end, Gatsu and the village elder revealed to the citizens that Gosunkugi confessed to his crimes and Sazanami was cleared of all charges.
