The incident with the Devil Believers had come to a close. This whole incident ends up hurting Nero, who witnessed the pain the Devil Believers felt from having less mana and reminds her of her time with the first Wizard King, Lumiere and the magic item he was trying to create to get rid of discrimination in their kingdom. She then gets summoned by Julius. Meanwhile, Asta and the others receive a message saying that the Heart Kingdom and the Spirit Guardians were ready to train them for their fight against the devil.
There's no doubt that the gap between 
those two is what caused this incident.
.لا شكّ أنّ الفرق بين الفئتين هو ما سبب هذه الحادثة
Ganz sicher ist der Unterschied
zwischen ihnen einer der Gründe,
La barrera que las separaba del resto
fue el origen del incidente.
La barrera que las separaba del resto
fue el origen del incidente.
Nous devons considérer
que c’est ce gouffre
Questo divario è senza alcun dubbio
 la causa scatenante dell'accaduto.
Não há dúvidas de que foi essa
lacuna que causou este incidente.
Судя по всему, испытанное ими отчуждение…
и послужило причиной всего это.
