Koyuki is a normal high school kid with a big problem: he can't stop himself from screaming at his crazy friends. He swears to himself each day that he'll stop, and each day he fails.
this world will become a living hell.
سيتحوّل هذا العالم إلى جحيمٍ حيّ
würde die Hölle auf Erden
über uns einbrechen.
questo mondo diventerà l'inferno in terra.
este mundo se tornará
o próprio inferno.
