this arc is really special, for the first time since the exorcist arc, Luxia is in a massive disadvantage since she can't rely on the system's power or tools in this world, the antagonist here is more cunning and downright evil, more so than any other we've seen in the previous arcs, she can't really predict what she'll do next since this is a game's world and not a novel's world. Even when she was in trouble before in the previous worlds she always came on top because she had some sort of an advantage but now she's got nothing but her wits and smarts which the villainess has somewhat equal amount of. This will be the world that will truly test Luxia to the extreme, I have no doubt she'll emerge as the winner and crush Nanako, but what I'm looking forward to is how will she do it.
