Finally I have time to read the two series back and forth.
I personally think that this is better than the previous work, both from the delivery and improvised arts.
This has more 'clear' concepts. Tense has been felt without having to spin in explaining the narrative.
But sometimes the absurdity becomes the deeper points that strengthen the bitter sensation. There is no psychological warfare between them, and more utilizing a spooky environmental drive.
This author is quite genius because he doesn't make the usual concepts to be predictable.
Also, I was touched by the closing words in the first volume. "If you are on the side to support the author."
Maybe I will consider buying the digital version in the future. It seems worth every penny.
