Intro
Summer... it is the season of youth, but also the season when nature bares its fangs at humanity.
Under the blazing sun, Guest was walking up a slope. The sound of water flowing from the canal, the noisy voices of elementary schoolers racing on their bicycles—all of it made Guest feel the reality of summer.
A curve mirror covered in ivy reflected and showed Guest's figure.
At that moment, the shadow of a person on a bicycle appeared in the curve mirror.
Oh! It's Guest! Whatcha doin'? You goin' somewhere now?
Ibuki rode up to Guest's side, got off his bike, and started walking right next to Guest.
