This is giving a big anime-enthusiast and possibly furry community vibe, it's really pretty separate culturally than just being a developer. For people who really are into it, it becomes a fetish... and no judgement for things that happen between consenting adults but... it can seem pretty odd from the outside. But it can also be entirely innocent, nothing wrong with liking certain art styles.

So if you don't understand these things best not to copy them because you could unintentionally be sending some pretty strong signals.

It's also somewhat in the style of the Manga Guides, which are fantastic and an entirely different way to make some of these things accessible.
