Season made to create some difficulty for the protagonist god with the insertion of souls that are a problem for his magical powers of god. And, in the final episodes it's just fanservice. Being inserted the maximum convenience that a script can give to the viewer: to solve everything in the base of the god power of the protagonist (which is basically an incarnate god).
The plot of souls/parasites/demons was even interesting, but the script and direction had the same problems as the first season and, even worse, they made a solution to the final problem of the last episode of the season, how to do it to please the children with the power of the protagonist god solving everything by magic (as a god should do), trivializing everything that was built during the 3 episodes of the inserted plot.
Note 4.
The strangest thing is that most people (I think people with developing intellect, like children, pre-teens and teenagers, or, worse, not even developed it) liked this second season more than the first. I believe it's because it's shorter and less tiring to watch because it has far less of those pseudo-classes on magic by the protagonist, but, in fact, it has the same technical, narrative and absurd script convenience problems with the power of the protagonist.
