I will survive by sacrificing 31 people.

We were abducted and imprisoned. What we thought was a classroom turned out to be a dark, sealed room. What's happening here? We attempted to escape, but nothing worked. Day after day, I felt my life slipping away. What should I do? And I survive. By sacrificing my entire class. I survive on the sacrifice of 31 people, and with limited plunder in hand, I pick a fight with the world.
