Shiin

Shin  is the leader of a group of bandits originating from the Land of Rice Fields, the same land where the Sound Village is located. It is revealed that there is a war currently taking place between the Land of the Rice Fields and other nations, mainly due to the actions of Orochimaru. As a result, the area that the raided village is in is a de-militarized zone, ruled by no-one, but with a gold mine on the mountain nearby. Bandits sought the mine, and raided the village to get to the mine.

Eventually, Shin attacks the village. Having difficulty with getting past the wall and defeating the Konoha ninja, he resorts to usong music to paralyse the Konoha ninja, but Menma counters the technique with his own music ninjustu. This allows Naruto to break Shin's flute, plus Tenten and a Neji to defeat the raiders.

Shin, realising the battle to be lost, retreats to the dam at the river. He planned to flood the village to drown the villagers. The gold mine would be left unharmed. Shin's plan to flood the village has been stopped when Menma make the mine collapse.

In the end, Shin is trying to escape but Naruto manages to catch with him and defeat him with Rasengan.

Trivia
