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.
Getting to use your power to the max in 
combat... What could be better than that?
...استعمال قوّتي إلى أقصاها في المعركة
هل هناك أفضل من ذلك؟
Die eigene Kraft im größtmöglichen
Ausmaß für den Kampf zu nutzen,
Quiero usar todo mi poder para combatir.
Quiero usar todo mi poder para combatir.
Mais pour utiliser mon pouvoir
à son paroxysme au combat.
Cosa può esserci di meglio che sfoderare 
tutto il proprio potere in combattimento?
O que é melhor do que usar o
máximo de seu poder em combate?
В бою я высвобождаю всё,
на что способен!
