I can't tell either, to be honest. I was using the same numbering system before I found that mega link. Even with the link, I can't tell if it's because some of them are remakes or if that's the numbering system he actually uses. The link has Servant's Sketch Training as number but doesn't have Yelan's Rescue Operation or Genshin Impact TikTok with UI, so who knows? I'm just changing it back to make it easier to understand.
