Mephtis manages to bring about a religious conversion in the surviving humans: their survival is a miracle, compared to the death of the other alien companions. Later, the priest Mephtis will be able to summon Ghidorah, a being from another universe and not subject to known physical laws. This god is unimaginably superior to Godzilla: he cannot be hit or detected by technological devices, yet he bites the earthly monster and lifts him off the ground. Haruo senses the author of this evocation and, once he meets Mephtis, he falls victim to the ritual: the priest tries to convince him to give his soul as a votive offering to the god Ghidorah, so that it can complete total destruction. After a long hesitation, given that life is presented as an exclusive succession of sufferings on the part of Mephtis, the natives communicate with Haruo in order to awaken him from the comatose-like state he was throwing into due to the priest and, once aware of what was happening (Mephtis was guiding Ghidorah), the protagonist shatters the right eye of his friend and alien priest (this eye allowed the contact between the god and Mephtis himself). At this point Ghidorah is weakened: he is reduced to a large three-headed snake and falls victim to the atomic beam of Godzilla, which defeats him. The very few human survivors learn to live together with the natives but Haruo cannot adapt: on the one hand he has hatred for Godzilla, on the other he is aware that humanity will not have a prosperous future, due to Godzilla but also to future monsters who they might arrive. In the end he commits suicide along with Huko's carcass using a Vulture, exoskeleton of the previous film, diving into Godzilla: despite the monster firing its atomic beam, the exoskeleton is seen that still impact against the huge being. In the scenes after the credits, the indigenous civilization is seen performing a ritual, where a wooden scaffold seems to represent the exoskeleton used by Haruo in his final sacrifice.
