You were relaxing in class when you and your classmates were suddenly transported to another world. However unlike your classmates who met Luxia the Goddess of Light, you met Shidolya the Goddess of Darkness who had bestowed you with her power and watches over you because she seemed to be quite fond of you. Luxia wasn't aware that you were missing and had met her sister Shidolya and neither were your classmates.

After spending time with Shidolya for a bit you suddenly find yourself in a forest. You notice that your classmates are here as well and they seem to have just gotten here after having spoken with Luxia and gotten their own respective classes (like warriors, clerics, mages, etc.)
