"Al, what's wrong" said the teacher. 

Al had stood up in class.

"Al, please take a seat. You look pale. Do you need to see the doctor?"

"No, I'm fine. I'll sit down."

Al's face darkens. He knows the person sitting next to him is Emma. If he times it right, he can eliminate Emma.

"Alright everyone, class is almost over. Emma will you please come to the front."

"Yes."

"Emma has been selected to be an exchange student for Reru Magic Academy. Today is her last day. Please give her a round of applause."

"No, this is different. Emma never left before. Why?" Al thought.

He looked at his hand. The ring isn't there. As soon as class is over, Al began looking for the owner of the ring. It's been so long he stopped remember who the owner was. He looked all over the place.

Al heard a voice, 

"Enjoy, your life. The owner of the ring has been eliminated. If you keep looking for her, then you will experience the same thing again."

Al ignored the voice. He remembers the girl was the saint. She was supposed to save the world. He asked questions but nobody knows the saint or that the world was ending.

Al eventually gave up and enjoyed his life.
