Uchiha Ichiyū (うち一幽, lit. Secluded Paper Fan) is a kunoichi from Konohagakure and the older sister of Uchiha Iki. Unlike her sibling, Ichiyū is cold, aloof and doesn't care much for her peers. In Ichiyū's eyes, anything that requires too much energy isn't worth doing and she often passes her jobs on to others. Mostly seen as hard to approach and antisocial; it is difficult to decide whether Ichiyū's lack of emotion is for better or for worse.
