When Hidden Sand retreated to their home country after their conflict with Leaf, Otokaze found the body of the Kazekage and his bodyguards. Hidden Sand then learned that they had been manipulated into fighting Leaf, by Orochimaru posing as their Kage.

Oowashi was approached by a man named Mousou, who used jutsu to impress the feudal lord. He was taken into the lords confidence and used the trust to poison and murder him and his song Sagi. Oowashi-s daughter Toki impersonated her brother and tried to hunt down her father-s killer. With the help of Naruto and ninja from Konoha, she exposed Mousou as the wandering ninja Houki, and brought him to justice.
