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.
The rift to the demon world is 
growing larger by the minute.
الشقّ المؤدِّي إلى عالمِ الشيطان يتوسّع بسرعة
Der Riss zur Dämonenwelt
wächst mit jedem Augenblick weiter.
La grieta del mundo demoníaco
crece cada vez más.
La brecha del mundo demoníaco
crece cada vez más.
La bouche de l’enfer s’élargit
de minute en minute.
La spaccatura che porta al regno dei demoni
si allarga minuto dopo minuto.
A fenda para o mundo dos demônios
está aumentando a cada minuto.
Разлом в мир демонов
растёт с каждой минутой.
