Review Detail of InHisName in My Attractiveness Only Affects Divine Beasts

This is somehow worse than 'Era of Beast Taming', at least in that novel the protagonist had to walk 10,000 steps to become legendary Pokemon master. In this story? The protagonist can literally sit on the toilet seat and suddenly, he'll find the Beast God of Time and Space just falling down from the Heavens to become his dutiful, mindless savant. To top of it all. The protagonist's personality is just amazing. He has about as much EQ as someone raised by wolves - his intelligence is similarly lacking. All in all, this is the type of protagonist that makes you think..."humans can't be that stupid? Can they?"
