Nonota is a Sunagakure shinobi. During the Fourth Shinobi World War, he and Musai were ambushed by a reincarnated Toroi. Musai recognised Toroi, and began explaining his abilities to Nonota, but they're attacked before he can finished. After Nonota was magnetised, Musai finished explaining Toroi's abilities to an increasingly apprehensive Nonota. Both are saved by the arrival of Naruto Uzumaki and Killer B, Naruto slamming Toroi with a Rasengan. As Toroi regenerated, Nonota proceeded to seal him. In the anime, after they left, Nonota and Musai were briefly suspicious of the other being a transformed White Zetsu as well, before realising the enemy tried to kill them both, meaning they were both on the same side. They laughed it off, and then Musai joked, pretending to be a transformed White Zetsu, only for Nonota to slash his nose with a kunai in defence. (Source: Narutopedia)
