These two gods are providing a public service for Japan. There's no actual violence happening here, so what's really happening is that the growing number of virgins in Japan are being distracted by an elaborate LARP. They get to have a lot of fun playing out their perceived greivances against the world in a mostly harmess way with other virgins while also getting magic powers. Meanwhile, the normies get to be blissfully unaware of their antics due to a passive attention and memory altering magic aura surrounding the magical girls and monsters.
