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 became strong to persevere over 
the House of Roselei's curse.
.أصبحت قوية كي أتحمّل لعنة آل روزلي
Ich bin stärker geworden, um gegen
den Fluch der Familie Roselei zu gewinnen.
Me hice fuerte para superar
la maldición de los Roselei.
Me hice fuerte para superar
la maldición de los Roselei.
Je suis devenue plus forte
pour briser la malédiction des Roselei.
Sono diventata forte per oppormi alla maledizione
che gravava sulla famiglia Roselei.
Eu me tornei forte o suficiente para perseverar
contra a maldição da Casa de Roselei.
Сильной… я стала, чтобы победить
проклятье Роузлеев.
