After a long battle, Choza is defeated and kakashi is left with barely any chakra. kakashi orders Choji to go and tell Tsunade about Pain's powers, and activates his Mangekyo Sharingan to save Choji from a fatal blow, knowing fully well that using it in his current state would very likely lead to his death.

Meanwhile, kakashi and the Asura Path are both rendered incapacitated.
