While Goblin Lord IS my favorite, yeah it's kinda crazy she can eat 6 girls. 3 or 4 makes sense, but I'm not even sure if Dusk Lamia should have a limit on it. I mean she said she's been eating girls for hundreds of years, let's assume she's just comparable in stomach space to Goblin Lord, so that's 4 girls there, and she has a massive tail that Lamia's store girls in so that'd probably be another 3, and that's assuming she doesn't have multiple stomach as a lamia, which she probably does.
