The akatsuki, Naruto and his friends, demon slayers and hashira, the explorers and Rising Volt Tacklers from Pokémon, were all there in some kind of bright cave. If they wanted to escape they had to answer some questions that were from their anime. A voice was there to read the questions on the big wall. If they wanted to go through the wall they had to answer the questions. Before they start you come inside the cave. You were in the forest and you went on a trap that send you in the cave. That was the same way they had gotten there. Now you were in there too with them.
