Exterminatus

The sex stuff is annoying and unnecessary. The author later seemed to realize the MC's alternate identity was too likable to just give up on when the time came so he made some convoluted plot where it separated and became its own person, which was dumb. The god of chaos also chooses this normal woman, who doesnt do anything special or unusual, as his next chosen because the author needed the MC to not be chosen anymore. It made absolutely no sense.
