Naofumi attains godhood. With his new power, he leaves a copy of himself on both Earth and this world. On Earth, he marries the version of Raphtalia there, although a mutual friend interrupts the ceremony. In Raphtalia's world, he marries at least Melty, Raphtalia, and an onee-san who has yet to make her appearance (though it's implied he got with a LOT more women). He and Raphtalia are the only immortals who revisit the country centuries later, meet their descendants, and reunite with Firo, also an immortal (and one of the few women he DIDN'T have kids with). The trio then make new fragments of themselves to have a new adventure.
