The spirit and its rotten former body were completely bisected by the blade, but it seemed to simply stun the zombie-ish creature that took the place of the formerly playful little boy's spirit. Perhaps this was the deep emotions that were rooted in the boy just before his death. Still, Ning felt a pain in his heart attacking the kid's body as it still held some resemblance to a child but for Atsuko's sake, he does not pull his punches. Though he truly didn't expect what he thought was a reckless action, of her using an explosive not at close range on the recovering spirit.
His cable like tail retracted quickly as it appeared just over his right shoulder, almost like some sort of scorpion stinger as he witnessed the corpse covered in a small amount of lava, one of the trademark elements of their great village. Yet, again he was surprised to find that not only was it not destroyed by the molten earth jutsu but was slowly breaking free. Ning needed to act, he had wanted to attack with his flame rune earlier but the tunnel was to tight and the distance between his new companion and himself was also to close.
But with her at more of a range and the spirit caught in between them it was time to act, "Protect yourself!" His voice echoed in the enclosed space of the rock tunnel before his hands came together forming a hand seal and chakra was released from his internal core to the seal in mouth of the puppet activated in turn with him opening his mouth. A deep fiery glow appeared within the dark orifice of the puppet body's mouth before a powerful wave of fire erupted forward feeling the entire diameter of the tunnel.
Ning had estimated the distance between himself and Atsuko to be enough that she should be just out of range of the attack plus there was the spirit's possessed bag of bones between them to also slow down the technique from advancing to its normal full range. The boy felt a chunk of his chakra reservoir used all at once from the attack as he was almost blinded by the sudden light produced by his own Katon attack that would consume the body of the boy, hopefully stopping it. If not at least providing the pair some room to link back up and escape, if it came down to that.
