is episode 89 of the Naruto: Shippūden anime.

Synopsis
Kakashi Hatake finishes off Kakuzu, and they return home. At Asuma Sarutobi's grave, Shikamaru Nara tells Kurenai Yūhi he will protect her unborn child. He plays Shogi with Shikaku Nara and reveals what Asuma told him: the "king" that Konoha must protect is the next generation. After studying Kakuzu's corpse, Tsunade tells Kakashi not to let Naruto Uzumaki use Rasenshuriken again because it will permanently destroy his ability to manipulate chakra. Meanwhile, Orochimaru learns of Konohagakure's latest victory against the Akatsuki and sends Kabuto Yakushi to meet with a woman named Guren.
