Iruma is trying to get back to the surface after exploring the underground labyrinth with Naphura. On their way up, he runs into his parents that shouldn't be in the netherworld. They're actually an illusion created by Orobas's magic. Iruma is overwhelmed by the illusion and falls off a cliff. Down below, Iruma continues to see nightmarish illusions. Will he be able to overcome his fears?!
If they do not all advance to the 
Dalet rank before their second year,

Si no ascienden todos a rango Dalet
antes de pasar a segundo,
En un seul semestre,
Se non avanzano fino al rango di Dalet
entro l'inizio del secondo anno,
Quando chegarem ao segundo ano, se todos
não conseguirem subir para o ranque Daleth,
До того, как перейдут во второй класс,
они все должны достичь ранга «Далет».
