The Mirror World that was activated is different from the Mirror World I usually activate. If my Mirror World only alters the surroundings, blocking everything that is happening from the real world, this Mirror World has another perk that I didn't like.
It occasionally shifts its surroundings and changes the structures. It was quite a troublesome thing since the school campus ground I am familiar with has now turned into a labyrinth. The good thing is that due to my Mana Scan and Godou's good sense of direction, we didn't get lost and we even managed to create a shortcut to reach the location of the enemy.
