You guys missed Deidara. He is technically still from Iwa. And Mu, ofc.

As for Suna, well, murderous families galore
lets see... Rasa, Chiyo, Sasori, Kankuro, Temari, Gaara, and Baki, the teacher.

Kiri... Ohh dear... Suigestu, Kisame, Chojuro, Mei, Gengetsu, Ao, Zabuza and Haku.
You need many friends for that.
Happy RPing!
