I was wondering why this was tagged as creepy when I remember watching the anime as a kid and finding it cute... I've had a cockroach crawl all over my face one time and multiple times on my legs so you just get used to them eventually, they're kinda cute with their big eyes and they're more scared of us than we are of them. No not that it's a good thing to get used to them, but you know how it is sometimes.
...Imagine a bunch of small girls all pale and soft coming out of an ootheca or, if it's a roach species that gives live birth, bursting out of the ass.
