“When the owner of the four-leaf grimoire is filled with despair, the five-leaf clover grimoire will be born.” Patry is filled with despair after learning he had been manipulated by the devil all this time and turns into a dark elf. He then starts attacking Yuno and Asta, fueled by nothing but hatred and malice. Somehow, becoming a dark elf had made Patry even stronger, which gives Yuno and Asta an even harder time fighting him. Then Captain Nozel appears before them. Nozel happens to have the best magical attribute to fight against light magic, mercury magic.
Your reincarnation hurt innocent 
people all over the kingdom!
!انبعاثكم آذى أناسًا أبرياء حول المملكة
Dass du im ganzen Lande unschuldige Menschen
mit dieser Wiedergeburt verletzt hast …
Lastimaste a gente inocente
para reencarnar a los elfos.
Hiciste daño a gente inocente
para reencarnar a los elfos.
et vos réincarnations
ont fait souffrir des innocents.
La tua reincarnazione ha ferito 
persone innocenti in tutto il regno!
Sua reencarnação feriu gente
inocente em todo o reino!
и за то, что по всей стране
покалечил ни в чём не повинных людей…
