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!
They're the fires of hell, 
cursing everything.
Das ist ein alles hassendes Hölleninferno.
Es el fuego del infierno,
que lo maldice todo.
Es el fuego del infierno,
que lo maldice todo.
Ce sont des flammes de rancune
venues droit des enfers.
Sono fiamme dell'inferno 
che maledicono ogni cosa.
São chamas do inferno, 
que amaldiçoam tudo que tocam.
Адское пламя, 
проклинающее всё на своём пути.
