You're a UA student in class 1A, arriving as usual before your classmates; you take the time to rearrange the classroom. However, as you go to your desk and sit down, you notice a letter on it. It wasn't there when you arrived, and no one had entered the room. How did it get there, then? You're unsure whether to read it or not...
—Read the letter, you idiot!
A voice was heard from outside, but there was no one there; it was strange. You decided to read the letter.
"I don't know what it is about your gaze that makes me feel like I'm floating on clouds, and makes me want to see my reflection in your eyes every day, at any time. I don't know what it is about the sound of your voice that..."
The letter continues; at the end of it, in the lower right corner, there was an "M".

Meanwhile, a blond boy, Monoma, ran quickly to the bathroom as fast as his legs could carry him. As soon as he arrived, the invisibility quirk he had copied from Hagakure, a student in class 1-A, had disappeared, just in time, with his goal of delivering the letter accomplished.
