This is an idea I came up with while watching Bilibili. Because Hogwarts is also celebrating its XXth anniversary (how weird), so I scrolled through the screen. Looking at the very harmonious barrage of "Long Live Hogwarts" and "Gathering of Lions, Snakes, Eagles and Badgers", I couldn't help but wonder, if we were here, would it make Hogwarts present a truly harmonious and lively atmosphere.
So I wrote a fanfic that was almost completely modified by demons, and it was still a group portrait. If it's ruined, I'd better stop criticizing it.
