"Negligence…!!" (油断…!!, Yudan…!!, Viz: Off Guard…!!) is chapter 126 of the original Naruto manga.
Kankurō attacks Shino with Karasu, but Shino avoids the attack thanks to his kikaichū. Karasu follows up with a poisonous gas attack. Shino just barely evades it, but in doing so walks into another attack. Meanwhile, Sarutobi continues to struggle to remove Orochimaru's soul. At the same time his likeness on the Hokage Rock cracks, worrying the ninja who see it. Shino is able to swarm Karasu with kikaichū but Kankurō still manages to get off another attack. The attack falls short, Shino having finally managed to guide his kikaichū to Kankurō's location. The kikaichū consume Kankurō's chakra and Shino passes out from the gas he earlier inhaled, trusting the rest of the battle to Sasuke.
