I expected the shadow world to be a bit more, err grim? I know the author what had meant and the idea behind it but with this random scenarios and game like pop-ups, I just can't take the story seriously.
I thought the shadow world will be like some sort of dungeon where it will spawn monstrous version of certain "historical scenarios" and they will have to apprehend some sort of goal/core.
Well anyways, I'll still be keep on tracking it since the early chapter's build up is really awesome. I just hope the story or this shadow world will improve further on.
