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 his magic was stronger 
than anyone else's.
.لكنّ سحره كان أقوى من البقيّة
Aber er besaß mehr
magische Kraft als all die anderen.
Pero poseía más poder mágico
que ningún otro.
Pero poseía más poder mágico
que ningún otro.
Mais il avait bien plus de mana
que ses camarades.
Ma il potere magico era maggiore
di quello di chiunque altro.
Mas a magia dele era mais
poderosa do que a de qualquer um.
Но в магической силе ему не было равных!
