Seiichi spends time training F-class for the upcoming class competition, but when the day finally arrives, Seiichi is nowhere to be found, leaving F-class to defend the academy from the apostles of the Great Devil Order!
You need only keep quiet and become 
sacrifices to the Great Devil.
Ihr müsst euch einfach nur in Ruhe
dem Dämonengott opfern lassen.
Tranquilícense mientras es convierten
en sacrificios para el Dios Oscuro.
Tranquilizaos mientras os convertís
en sacrificios para el Dios Oscuro.
Veuillez vous taire
Vi preghiamo di rimanere tranquilli
mentre diventate sacrifici per il Re demone.
Quero que fiquem quietinhos e sejam
o sacrifício para o grande Majin-sama.
Пожалуйста, не кричите слишком, 
ведь вы — жертвы Великому дьяволу.
