An amazing story. Nice to see more quality giantess stories at the Giga and Tera size. The introduction did not feel too long at all, it felt just the right length. I liked how after the girl grows, she and the tiny people automatically regard her as a goddess. That showed just how impactful her transformation was.

Will be fun to see where the story goes from here. You seem to have a lot planned - at least the tags seem to promise that much. I wonder how she will end up growing even further (does she remember the words?) and just how large she will ultimately become. It will also be interesting to see what exactly motivates her. At first a motivating factor seems to be getting revenge. It is interesting to see how that changes. It does not sound like she will just obliterate everything in moments. The story seems to hint this with the following: "Their bodies were unidentifiable.". So at one point the little people will probably have time to go and measure the damage she has caused. 

Overall,the story was a great read thusfar and I am interested to see where you take it.

Very well written and good size as well. I'm really liking it so far, though I am wondering where it will go from here, since longer stories become harder the bigger the giantess is.
