This book is about a protagonist who can't stand the endings of certain anime and is always complaining about them. His overwhelming resentment startles the Source God, who is smoking nearby, and the god accidentally drops some ash on him. After signing an unequal treaty with the protagonist, the god sends him to transmigrate. This is a wish-fulfillment story. If that's not your thing, don't read it.
