Well, I noticed onemanga.com uploaded new chapters for Dragon Quest: Dai no Daiboken so I decided to continue where I left off. Couldn't believe I would find a fake hourglass expansion on this series too. First Detective Conan and now this. It takes place on ch. 187 when Dai's group were waiting for him and his father open the gate to their enemies' palace. Then Pop (the mage) notice a change on Marm (the fighter) in her figure. It seems her breasts and rear have gotten bigger than they usually were and then decided to poke on those mentioned spots then suddenly her breasts and butt blow up instantly and came up Dai's golden slime, Gome-chan. Basically, the fake growth was cause by the slimes flying around in her clothes very quickly. Here the links to the pages and see for yourself.

Heh, that makes two expansion finds I made in onemanga.com so far. Anyway, this series also has an Anime series too but I don't know how far it went. I will try to find out more if there's an episode that takes place in that part of the storyline. Comments are welcome.
