Yūdachi

is from Amegakure, though he has a scratch through the village symbol on his headband to indicate his loyalty to Pain. He and his partner, Ryūsui, are captured by Jiraiya. When they refused to tell Jiraiya any information on Pain, he uses a feather to tickle-torture Yūdachi into giving him the info. When this failed, Jiraiya transformed Yūdachi into a frog, which cowed Ryūsui into divulging info about Pain.

Jiraiya sends Yūdachi to Konoha, where he is interrogated by Ibiki. When Ibiki can't learn anything from him, Inoichi probes his mind and discovers that Yūdachi used to bring dead bodies to Konan, not knowing what they were being used for. He is apparently killed by the Animal path during the invasion of Konoha.
