Strange Arm Flaming Arrow (Kaiwan no Hiya) is a Ninjutsu technique used by Pain. One of Pain's bodies is modified to detach his hand and fire it like a rocket. Upon focusing chakra to the wrist, the hand will be launched towards the target. This chakra will also act like a magnet to pull back and reattach the hand. The chakra also protects the hand, allowing its powerful strike to severely damage rock, but not the hand itself.
