Resuming in the immediate aftermath of the battle from the first movie, CotEtB expands further on the lore of this world, introducing the [spoiler] remnants of the MechaGodzilla City and an evolved race of humans [/spoiler].

With Haruo and his team looking for newer means to fight and defeat Godzilla, they sign what is effectively a deal with the devil. We see Haruo's character developing quite a bit in this movie as he has to make some hard choices, couple of which do not end well.

Similar to the first part, this movie too flirts with speculative sci-fi, delving into questions of human evolution aided by Science vs evolution taking place naturally. However, much like the first movie, this installment too does not commit itself to deeper discussion, leaving it up to the viewers to make their own mind.
