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.
There might not be anything I can 
do to atone for what I've done.
قد لا يكون هناك ما يمكنني 
.فعله للتّكفير عمّا فعلت
Egal, was ich auch tue,
ich werde das wohl nie mehr gutmachen können.
Quizás jamás pueda redimirme.
Quizás jamás pueda redimirme.
Faire pénitence de mes péchés
est sans doute impossible…
Probabilmente non potrò mai
fare ammenda per quelle azioni...
Pode não haver nada
que expie o que eu fiz...
Возможно, мне никогда
не искупить содеянного…
