In the tower each prisoner gets 100 points and they all have random powers like quirks. They need to go to the arena to kill and get points. This is how to enter the arena. You need to find someone who will also fight you. And you need to go to 1 door and each door must only contain 2 people. And they will get teleported in the arena with their partner. And they fight to the death. Winner gets 1000 points. The more delicious the food it will cost more points. And no fighting in the main lobby
