Thanks for the explanation. I wondered if there was some interesting reason behind this, specially seeing how the townsfolk was cheering for them. I love the concept of a couple growing through sex to protect their city from some menace, getting so into it that they allow themselves to become a hundred times bigger than the city.
I guess you can see some growth, at the beginning the townsfolk seemed to be the size of their toes, and in P.16 they might be about 1/4.
But it would have been awesome if he had shown the growth from mega to giga, something like:
- P.15: 200 - 300 - 500 meters
- P.16: 1 - 2 kilometers
- P.17: 5 - 10 km.
- P.18: uncertain size (orgasm) - and that last panel where they are like 200 kilometers. Or a bit more gradually through 10 pages or so. Still it's a pretty awesome sequence if you use your imagination.
