As the story advances, I feel like I'm reading something different from the original story. I get that the author wants to give us different scenarios in every game. But I feel like the plot continuously becomes more and more boring and we keep going in an endless loop. What was supposed to be a fight between a Witch magic and human logic somehow turns into a magic fight and the truth feels lost in the middle of it, characters that never ever seen a witch suddenly starts fighting using magic and summoning demons like it's the most natural thing on earth.
I think I gave 5 & 6 a fair read but I still feel something missing after the first 4 episodes.
