If  you're wondering what's going on you may have to read chapter 1 and 2 for a better understanding.

If you really don't understand what this chapter is about, here a summary:

After trying out the urban legend at midnight, Avril was both shock and confuse about how she was able to get her arm into the mirror. With many questions running through her head, she decided to tell her friends on the next day. However, not even her friends were able to figure out how these strange events happened. Grafl suggested (or it seems) that they should go to the Gaia Supermarket to find the a larger mirror to test out the teleportation for themselves. And without a second thought, Avril agrees with Grafl and all 6 of them sets out to the Gaia Supermarket to find the largest mirror to test out. Selena warned her that this test wouldn't work but Avril went ahead and enter the teleporting mirror to the Nocturnal forest. Avril was soon greeted by two fairies and has told her that her great grandmother has passed down her abilities to summon units to Avril. Now even more confused, she ask them how this was possible but suddenly, they were intruded by unknown enemies.
