“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.
I don't need a reason to save 
someone who's about to die.
.لست بحاجة لسبب كي أنقذ شخصًا على وشك الموت
Ich brauche keinen Grund,
um jemandem das Leben zu retten.
No necesito razones para salvar
a alguien que se está muriendo.
No necesito razones para salvar

Pas besoin d’une raison pour aider
quelqu’un sur le point de mourir,
Non mi serve un motivo per salvare
 una persona che sta per morire.
Eu não preciso de motivo para
salvar alguém à beira da morte.
Мне не нужна никакая причина,
чтобы спасти умирающего!
