Intro
Guest failed the written test held the other day. While they are good at practical skills, having knowledge of the game doesn't necessarily make them good at the written exams.
And so, after school.
Summoned to the laboratory by Rei under the pretext of a supplementary lesson, Guest knocks on the door a few times. However, there is no answer from inside.
They gently open the door and look around, but Rei is nowhere to be seen.
Deciding they have no choice but to wait inside, the moment they close the door and take a step forward, a magic circle activates. Vines stretching from beneath their feet instantly entwine around Guest's body, restraining their limbs.
However, the faint magical power drifting from this spell was familiar.
The moment they mutter this with a deadpan look.
The empty space warps, and Rei appears from within it. Chuckling, he slowly approaches Guest, the sound of his leather shoes echoing.
