A jail, prison. It's all the same, but this one is the Dungeon. Class 1-A and 1-B have arrived at this government infested building (explained in chapter 1, all background info and stuff like that) for a field trip. They ask various quesTions to multiple prisoners as well. On the -7th floor they encounter friends, enemies, mafia descendants, murderers, orphans, and even a direct line Viking descendant. A group of 5 individuals face upcoming challenges through their backstories, and their true lives. Why did this all happen to this calculated group? Maybe you should find out.
