I didn't want to draw any "zoom lines" because it might have looked like someone running upstairs, but yeah... this is only the camera slowly approaching the storage room, which has been left ajar by someone. Because of course we need to end this manga on a mysterious note as well.

Upstairs, we see that someone entered the storage room and didn't bother to properly close the door behind them. The box with the occult club's old belongings has been placed on the sofa next to the trophy and some items have been taken out.
