Urushi

ウルシ

Urushi is an orphan who resided in the Konoha Orphanage. He subsequently became a shinobi of Konohagakure.
At some point, Urushi, along with other children and Nonou from the orphanage, discovered a wounded young boy beneath a tree. After Nonou healed him, Urushi helped the boy return to the orphanage with the group. The following day, he remarked that it was odd for someone to lack a name, so the nun decided to call him Kabuto, after the helmet Urushi had placed on the boy's head.
Over the years, as the orphans assisted Nonou and Kabuto in treating certain Konohagakure shinobi, Urushi objected to helping ninja, but understood that they needed the money and dutifully assisted them.
