Oyone

is a medical-nin of Konohagakure.

Abilities
Being put in a team alongside Shizune and Kumadori to analyse the captured body of Pain's Animal Path proves that Oyone has a great knowledge about medical ninjutsu. As a medical-nin, Oyone must also have an excellent chakra control.

Invasion of Pain Arc
Oyone and Kumadori were selected to assist Shizune with the autopsy of the Animal Path. Through their investigation, they were able to determine that the black rods that appeared to just be body piercings, were actually chakra receivers.
