Before leaving the Inagara Clan, Odaiba had made his own weapon with the technology used for their tools. This new weapon wound around the forearms like gauntlets, and had a handle to grip. It allowed elemental chakra to be gathered around the fists. He hadn’t told his clan about the gauntlets, fearing they would confiscate them. After the battle with his son, the gauntlets are now in Oda’s possession. The Inagara Clan eventually learned of their existence when Oda finally met with them.
