Nanashi Uchiha (うちはナナシ, Uchiha Nanashi), formerly known as Hikari Uchiha (うちはヒカリ, Uchiha Hikari) was a kunoichi of the Uchiha clan during the Warring States Period. Because of her extraordinary abilities, Nanashi was treated as nothing more than a weapon by her own clan and was always locked away in a cell, only being called out for battle. She was ultimately sealed away by the combined efforts of the Senju and Sarutobi clans. She was released almost a century later by Merz.
