After using forbidden magic in the fight against the devil, Secré turns into a bird and ends up spending centuries all alone. During that time, she ends up meeting Asta, who ends up with Licht’s grimoire that has a different devil residing in it. Patry ends up reviving due to resurrection magic, and then he becomes the leader of the Eye of the Midnight Sun and vows to get revenge. This was all according to the devil’s plan and Secré uses her sealing magic to free Lumiere and Licht so they can finish off the devil once and for all along with Asta. The battle comes to an end, and Secré now begins her new life as a member of the Black Bulls.
Even if it meant dabbling in forbidden 
magic, he gave us our last hope!
حتّى وإن عنى ذلك استعمال السحر 
!المحظور، فقد منحنا أملنا الأخير
Auch wenn er seine Hände
mit verbotener Magie beschmutzt hat,
Aunque fuera usando Magia Prohibida,
Aunque fuera usando Magia Prohibida,
Il s’est corrompu
avec un sort interdit
Ci ha dato lui la nostra ultima speranza, 
anche se per farlo ha dovuto usare la magia proibita!
Mesmo que isso significasse flertar com magia
proibida, ele nos deu nossa última esperança!
Даже испачкав руки запретной магией,
он вверил в наши руки…
