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.
I think... the queen is generating 
a force field made of mana,
،أظن... أنّ الملكة تولد حقل طاقة من المانا

 una barriera di mana,
Eu... acho que a rainha está lançando
um campo de força de mana
