I see the final ending as the fusion of Coral's collective consciousness with human minds fully merged with the mechs. No remaining human bodies but fully merged with the mechs as their literal bodies now. Thier more natural movements are due to being the mechs and not people piloting a mech by one degree of separation. Also while Raven was oitz the Coral rewrote the universe to better suit their needs.
