Shinko Inari is a former kunoichi of Konohagakure. Shinko and her family moved to Konoha when she was nine. However, she retained her foreign accent, making her easily identifiable as not native to Konoha. After graduating from the Academy and becoming a genin, Shinko, Itachi Uchiha, and Tenma Izumo were placed on Team 2 under Yūki Minazuki's leadership. To Shinko, it was obvious that Tenma was jealous of Itachi's skills and, moreover, that Tenma would never be able to surpass him. For this reason she pushed back against Tenma's frequent criticisms of Itachi and encouraged him to start valuing Itachi as a teammate. She placed some of this blame on Itachi as well, pointing out that his independent streak only incited Tenma into making poor decisions.
