Synopsis
As the Six Paths of Pain and Konan try to determine Naruto's location, Danzō tells Homura and Koharu of Pain's arrival. They confront Tsunade on the matter, trying to make her change her mind about Naruto. She becomes furious at them and tells them that they need to believe in Naruto as he is a member of Konoha just like all of them. Shizune arrives and informs Tsunade of Pain's chakra receivers. Tsunade makes her way to the roof of the Hokage Residence. Meanwhile, Kōsuke, the messenger toad, prepared to return to Mount Myōboku to inform Fukasaku about Pain's invasion, but is killed by Danzō, the latter claiming that the Nine-Tailed Fox was no longer a problem. Tsunade summons Katsuyu and tells it to attach itself to the villagers. The Deva Path tries to attack Iruka, but he is saved by Kakashi, who confronts the Deva Path by himself.
