Furrow (轍, Wadachi) is chapter 655 of the Naruto manga.
As the tailed beasts all start to take corporeal forms, they gladly thank Naruto for saving them. Rushing forward suddenly, Sasuke heads towards Obito's location with his sword drawn; his intentions clear. With other sensors such as Cdetecting that Obito was still alive, the Alliance mobilise to deal the finishing blow. However, both Sasuke and the Alliance are stopped by Kakashi's reemergence on the battlefield and Tsunade's orders respectively. Kakashi informs his former student that this burden was his to bear as he was Obito's friend, but before Kakashi can deal the blow to a resigned Obito, he is stopped by Minato. The three men talk about the past, their regrets over Rin's death and how everything had turned out. Kakashi then tells a doubtful Obito that Naruto would not turn out the way he they did because if he faltered, he had friends and support that would help him back up. All throughout this, Naruto had moved to locate Madara and Hashirama in order to aid in sealing the Uchiha. Standing atop the tree form of the Ten-Tails, Naruto and his shadow clones form the Big Ball Rasenshuriken which they continue to increase in size until it becomes like a giant beacon above the battlefield, that illuminates his comrades' footsteps.
At the start of the chapter, when Sasuke rushes towards Obito to deliver the final blow, his eyes are in his originalMangekyō Sharingan form. This wasn't corrected in the tankōbon version.
