The Black Bulls were ordered by the Wizard King to investigate the devils. Yami takes Asta and Nero and goes to talk to Captain Charlotte of the Blue Rose Knights, since she has experience with forbidden magic and curses. But when they get there, Charlotte suddenly runs off somewhere and they’re all in shock. Charlotte had memories of while Charla took over her body and fears that Yami had found out her true feelings and she ended up panicking. But then, she makes a decision.
I was just hoping you could tell 
me about the forbidden magic...
...كنت آمل أن تخبريني عن السحر المحظور
Ich wollte eigentlich nur von ihr
mehr über verbotene Magie erfahren …
Yo solo quería una pista
sobre la Magia Prohibida.

Je voulais juste

Eu só queria saber se você podia

Вообще я пришёл расспроить тебя
про запретную магию…
