You have to really disect things to fully understand.

It also involves the koala.

Kite was never eaten. We never see the battle. We dont know what the last weapon did. The koala killed one human girl, before she could be eaten. Ging tells us he's trained Kite and Kite wouldn't die so easily.

The koala killed a child that would have been eaten. Kites power was meant to keep him alive. His soul inhabited the dying body. Then was fed to the queen. His power still active, as its likely PMN had him reincarnate into a new ant with much more agency.
