After absorbing the dark chakra of the two Narutos, Naruto felt as though his body was about to burst. He swelled painfully and fell helplessly from the air. Sasuke and Hinata, who was nearby, rushed over. Sasuke quickly asked, "Naruto, what's wrong?"

Everyone was startled, but Sasuke said calmly, "It's fine. Madara Uchiha
