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.
Hey, Teach... Did you happen to bring 
anyone important to you into this forest?
معلّمي... هل أحضرت شخصًا مهمًّا 
بالنّسبة إليك إلى هذه الغابة؟
Herr Lehrer, haben Sie nicht irgendwelche Ihnen
wichtige Menschen mit in den Wald gebracht?
Dites-moi, maître,
Di', Maestro... non è che nella foresta
 c'è qualcuno a cui tieni, vero?
Ei, Sensei... Você trouxe todo mundo
que é importante pra você pra floresta?
