"When It Turns 9 o'clock" (9時になったら, 9-Ji ni Nattara) is chapter 587 of the original Naruto manga.
Using this time, Sasuke questioned his brother about Izanami. Itachi explained the mechanism behind the technique, the history of their clan, their use of Izanagi and why Izanami was created. He then told his brother that Kabuto would be freed from Izanami once he accepted his fate. Somewhat angered that Itachi would use a technique that the victim could escape, Sasuke questioned his brother who told him that he wanted to give Kabuto the opportunity to accept his fate — something he himself could not do during his lifetime. This explanation only served to irate Sasuke more who believed his brother to be perfect, but Itachi refuses this claim. All throughout this, Kabuto continued to battle on in his mind, refusing to give up. Elsewhere on the battlefield, a grown up Urushi, told one of his comrades about his home and hoped that by the time he got back, his brother, Kabuto, would be there. Meanwhile at the cave, Itachi prepared to end the Summoning: Impure World Reincarnation.
