The Misfit Class is in the middle of a flying race in order to determine their ranks. Since Iruma is human, he can’t fly, so he’s riding on the back of the giant baby demon bird, but it seems to be flying off course. Meanwhile, Sabnock decides to go through the treacherous Cutthroat Valley and ends up having to battle it out with the Guardian there. Sabnock is obsessed with becoming the next Demon King, but why is he so obsessed? Are Iruma and Sabnock going to be able to make it out of Cutthroat Valley alive?
You were about to try to blow 
Iruma-kun's arm off, weren't you?
كنتَ على وشك أن تحاول تفجير 
ذراع إيروما-كن للتّو، أليس كذلك؟
Du wolltest doch gerade
Iruma-kuns Arm wegblasen, oder?
Ibas a arrancarle el brazo a Iruma,
¿no es así?
Ibas a arrancarle el brazo a Iruma,
¿no es así?
Tu allais faire exploser
le bras d’Iruma, pas vrai ?
Stavi cercando di far saltare il braccio 
ad Iruma poco fa, vero?
Você ia tentar arrancar o
braço do Iruma-kun, né?
Собирался кольцо
вместе с рукой уничтожить?
