The Secret of the Impure World Reincarnation

Summary
Naruto continues to practice making the Tailed Beast Rasengan. Tobi orders Kabuto to kill Anko, but he says he can get stronger by absorbing the remnants of Orochimaru's chakra that is in her, so instead, he has Kabuto show him how Summoning: Impure World Reincarnation works, by having him use Fū to resurrect Torune, whom he just killed. Kabuto does so. The Allied Forces learn of the White Zetsu Army moving underground. The Surprise Attack Division continues their assault.
