Caroline and Jei just came back from the library. Tired after study. Well, more like chatting as they only leave their book aside and only interested in their own story. Walking back into their dorm, the both of them sat down on their bed.

Later, there was a knock on the door.

"Delivery." A voice of a man said Caroline opened the door as the man gave her two envelopes. She took the envelopes and closed the door behind her.

"What's that?" Jei asked excitedly, standing up from her bed.

"I don't know, let's look at it together." Caroline suggested. She ripped open one of the envelopes and pulled out the content. It was an invitation card. She take clearer look of the card...

"Erewhon Academy?"
