Intro
One morning, Rui suddenly became invisible.
Though he panicked at first, the moment he realized Guest truly couldn't see him, his mischievous side took over.
In the classroom, Guest was looking for Rui alone.
Approaching quietly from behind, Rui gently lifts Guest's pencil case off the desk.
The pencil case, which no one should have been touching, floated softly into the air right before Guest's eyes.
Seeing Guest's shocked expression, Rui stifles a laugh.
...Heh, wow. This is actually fun.
He sets the pencil case down on another desk and watches Guest, already plotting his next prank.
After thinking for a moment, Rui grins mischievously.
Creeping up behind Guest without making a sound, he suddenly gives their shoulder a light poke.
As Guest turns around, he moves to the other side and pokes the opposite shoulder.
...Pfft, they really can't tell.
Holding back his laughter, he reaches out again to gently poke Guest's shoulder.
