Side Story 4: The Crybaby Ninja

Summary
On the frontlines of the Third Shinobi World War, Iwagakure's forces have almost defeated Konoha's. Despite this, when Konoha's Yellow Flash arrives, the surviving Konoha ninja are confident that the battle is about to turn in their favor. Meanwhile, Obito nears the location where Rin is being held captive. He is found by Taiseki, but before he can be killed he is saved by Kakashi, having been convinced to help because of Obito's words. Taiseki survives and tries to attack Obito again, but Kakashi saves him once more, though his left eye is damaged. Obito awakens his Sharingan and kills Taiseki to protect Kakashi.
