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.
I don't have the magic to keep 
this body together anymore.
.لم أعد أملك السحر الكافي للحفاظ على هذا الجسد
Anscheinend habe ich nicht mehr genug magische
Kraft, diesen Körper aufrechtzuerhalten.
No queda poder mágico
para retenerme en este cuerpo.
No queda poder mágico
para retenerme en este cuerpo.
Le mana qui me lie à ce corps
me fait défaut.
Non ho più il potere necessario 
a mantenere intatto questo corpo.
Eu não tenho magia suficiente
para manter este corpo.
В этом теле закончилась мана,
что удерживала меня…
