Obviously, if the answer is to much of a spoiler or something, this can be locked/deleted. :3

Just wondering for Trivias in general:

Are they related specifically to Subeta, or have there been ones related to the real world?

They used to be real world related (check out numbers less than 200 or so here) but I believe now they only use Subeta related ones.

Okay, thanks :3 That's very helpful, since otherwise, I either knew the answer, or had to do some searching xD Looks like it's searching!
