A creature named Kyubey offers Madoka and Sayaka a wish if they agree to become 'magical girls' and fight abstract beings called 'witches'. However, a magical girl named Homura is, for uncertain reasons, determined to stop this agreement.
The witches' mazes are usually surrealistic environments.
When Kyubey explains entropy, he says it involves the net loss of energy, which is not possible in physics. What the term actually describes is the decay of energy to its base form - which is heat - and its subsequent scattering through space, until the system reaches equilibrium, at which point all energy conversion ceases until further external energy input.
