Fun fact: The Earth's moon has no magnetic field because its metal core has long since cooled down and stopped spinning. As far as we know, magnetic fields have no tangible effect on human reproduction (gravitational fields, on the other hand... let's just say it's hard to have sex when your entire continent is flooded by high tides). And even if the Moon's orbit suddenly began to decay at the stated rate (ca. 384.4 km/year), it would have hit the Roche limit and disintegrated into an asteroid ring around Earth 38 years before the manga even took place.
I am sorry to all the catgirls who died when I brought real physics into a fantasy manga, but I am supremely peeved by sloppy worldbuiding from an author pitched to me as a "fantasy genius".
