Ōnami

is a miner in the Land of Water.

Personality
Ōnami is a well-meaning, but trusting man. In his capacity as chief, he rushed to hire miners to boost the economy of Dotō Island, but neglected to run background checks, allowing bandits to infiltrate his crew. As such, his two-shift plan at the mines, which was arranged to avoid anyone stealing gold, ended up helping the bandits. He also takes things at face value, becoming concerned by Konoha sent him only Team 5, and judging Denki by his appearance. However, he is capable of owning up his mistakes, apologising to Denki for how he judged him after Team 5 apprehended the bandits and recovered the gold.

Great Sea Battle of Kirigakure Arc
Following the discovery of gold deposits at Dotō Island, Ōnami became the chief of the mining operation to extract it. As the mining was dangerous due to complex geology, Ōnami commissioned automated puppets from the Land of Fire. While he was unsure that Team 5 was up to the task, he was impressed to learn that the package Denki was struggling to carry up the trail to the mine was heavier than even he could lift. At the mine, he showed up the puppets to his crew, but was taken hostage by bandits who had infiltrated. The bandits locked them inside, but Denki was able to use the puppets to create an escape. After Team 5 apprehended them and recovered the gold, Ōnami apologised for his earlier judgement and praised Team 5.
