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?
I've never heard of the Ring of 
Solomon producing black flames.
.لم أسمع قط أنّ خاتم سليمان يُصدر نيرانًا سوداء
Ich hab noch nie gehört, dass Salomons Ring
einen schwarzen Rauch absondert.
Nunca oí de un anillo de Salomón
con llamas negras.
El anillo de Salomón
no debe tener llamas negras.
Il n’a jamais été question
d’une fumée noire sortant du sceau.
Non ho mai sentito che l'Anello di Salomone 
produca delle fiamme nere.
Eu nunca ouvi falar que o anel de
Solomon produz chamas negras.
Впервые слышу
 о чёрном пламени из кольца Соломона.
