Yuno, Kuro, Jay and Lukas are the four boys organizing the tournament. The competitors are so tiny that the bodies of these four boys resemble continents by comparison. The four boys will each take turns putting the tiny competitors through deadly trails involving their giant bodies. The four boys will try to make the tiny competitors fail, and they will often bend the rules. The tiny competitors will all be shrunk even smaller after each round, down to micrometers or even nanometers.
