Zuro is one great biologist. Even though he set up a killing game, he studied the lives of every student and then conducted an experiment to see which students could survive the longest. That was why he made the final killing game. He's a friendly sort of person but since he was full of despair, he couldn't bear the thought of another killing game, so he ended the final one and destroyed the megamart for the sake of Cole. He brought back everyone and told Cole to evacute the megamart. The voice required is a male voice of any pitch.
