Purson himself wasn't relevant to the plot until now. Why was he foreshadowed? Maybe because it would be an asspull to add a new character out of the blue? It's almost as if the author understands these things need set up.
Sure, we may have been at the school past 5 PM a few times, but at those times, we've always been in some other plot-relevant event. Do you really think the author would pull away from reading with Amelie to point out something right out of left field?
dditionally, the way the characters act when Purson plays means that this is a common occurrence, almost like a bell ringing on the hour to tell us the time. Why would the author pull us away from whatever's happening to make a point of this common occurrence unless it was directly related to the plot
There's a simple resolution to this, he stops reading when he hears the trumpet. "Oh Amelie, do you hear that? That's the pixie, I guess story time is over for the day." Did you see what I did there? I integrated foreshadowing without taking away from the subject of the scene. He only had to do this once.

You have it fundamentally backwards. It's because it was directly related to the plot
now that it should have been mentioned
earlier. If Iruma showed up next chapter with Hell's Tuba, the most powerful and beautiful music instrument in the underworld that will guarantee make their musical performance a success, would you find that an asspull? Why? Is it because there was no mention of it previous?
In conclusion, stop bitching and enjoy the story. Not everything needs to be hidden in plain sight (as Purson himself was), and not everything **can** be foreshadowed either.
You're arguing it was impossible for the author to foreshadow the pixie but not for him to foreshadow Purson himself? That's pretty self-contradictory.
