While Asta and the other Black Bulls were fighting with Fana, Fanzell was facing off with the forces of the Diamond Kingdom, which he used to be a part of. The forces happen to be led by two of Fanzell's former students, Ladros and Mars. Fanzell left the Diamond Kingdom because he didn't agree with the kingdom's methods, but before, he would train children on how to use their powers for the Diamond Kingdom. Fanzell tries to reason with his former students, but Ladros attacks regardlessly, forcing Fanzell to fight with them.
But there are limits to how 
much I can do by myself.
.لكن هناك حدّ لما يمكنني فعله بمفردي
Aber für meinen Alleingang
hier gibt es auch Grenzen.
Pero solo no puedo hacer mucho.
Pero yo solo no puedo hacer mucho.
Però ci sono dei limiti 
anche a ciò che posso fare da solo.
Mas há limites para o que
eu consigo fazer sozinho.
