lol, novice. XD

Best Google can get me is that "doujin" is a word of Japanese origin meaning a group of people or friends sharing a common interest. I don't think that's what you meant though, since it makes no sense in your context. Probably just a hilarious accident, like when I named a video game character "Kyar" before learning that kyar is a name for coconut fibers.

All of which is a long-winded and rambling way to say I've no clue what this sketch is about; but it's pretty and I especially like the expression on it.

I can imagine a whole ring devoted to fandoms. "What got you here?.... OOoooo! Do you still have a link to that?"

That is so funny to me XD
