>>54393937Weirdly serious answer given the subject, but I would say that it's because porn of characters has a recursive effect of sorts where characters that are popular right out the gate will get a huge wave of porn, and then keep getting more daily (whether it's more mainstream popularity like Misty or Cynthia, or a character that weirdly becomes a meme like Hex Maniac), but a character like Sina who is a secondary NPC at best just won't get jack shit because she requires you to actually play the game to know who she is in the first place (you probably underestimate the amount of porn artists who don't actually touch the source material of what they draw), and even then it's still easy to forget she even existed.
