Suddenly, all of Babyls is surrounded by invisible walls! On top of that, they are unable to get a hold of the outside and there are invisible walls that popped up all over the school. Amidst all the chaos, Kalego and the other teachers have the students take shelter in the central plaza. Since Kiriwo is missing, Iruma decides to go look for him with the help of Asmodeus and Clara. Will Iruma be able to find Kiriwo?
Apparently the invisible walls, 
or barriers, are all around the schoo—
يبدو أنّ الجدران الخفية أو الحواجز 
—منتشرة حول المدرسة كلّها
Überall in der Schule sind
transparente Wände, eine Barriere …
Hay barreras invisibles
por toda la escue…
Hay barreras invisibles
por toda la escue…
Un sort de barrière
a dressé des murs invisi…
Sembra che i muri invisibili, le barriere, 
siano ovunque nella scuola—
Aparentemente, as paredes invisíveis,
ou barreiras, estão por toda a escola...
Невидимые стены — барьер —
стоят по всей школе…
