"The Number One Strongest Enemy!!" (一番強い敵!!, Ichiban Tsuyoi Teki!!) is chapter 196 of the original Naruto manga.
Kidōmaru fires an arrow at Neji's blindspot. Neji, having suspected his blindspot had been discovered, is able to dodge enough to keep the attack from killing him. Kidōmaru realises that Neji must have surrounded the area with chakra to compensate for his blindspot and pick up on anything that approaches from that direction. Disappointed that the strongest "character" of the Sasuke Retrieval Team has been figured out so easily, Kidōmaru modifies his arrow to make it faster and adds a string to guide it mid-flight. Once a fleeing, injured, exhausted Neji presents his blindspot Kidōmaru fires again and it successfully hits him.
