During the Uchiha Clan Downfall, Itachi came to her to begin the massacre with her as he was told by Danzō Shimura that he could only spare his little brother Sasuke Uchiha. Believing that ending her life first would quell his inner doubts, he proceeded to kill her and her mother first. As he lured her mother away, Itachi approached Izumi and placed her in an extremely powerful Tsukuyomi where she lived the entirety of her life in 0.000000001/th of a second. In her dream, she became a chūnin, retired from shinobi life to become Itachi’s wife and raise their children, and lived to become eighty years old before dying of old age alongside Itachi. Because her mind was departed from reality in such a manner, Izumi collapsed into Itachi’s arms dying. Izumi thanked Itachi for giving her the life she wanted with him, even if it was a dream, and Itachi thanked her for loving him as she passed away peacefully.
