Giantesses are usually considered to be bad, but this is a common mistake. They do not always do evil. Just the opposite – sometimes they save the world from evil creatures.
Let’s take this occasion as an example. The planet was attacked by big dragons and tiny humans couldn’t deal with them. They tried everything but in vain. And this is when the giantess came to give him a hand… or I may say foot. With just the only one step she made, the world was safe again.
