“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.
but I can definitely sense 
Captain Vangeance from him.
.لكن يمكنني الشعور بالقائد فانجانس منه
Aber ich kann bei ihm definitiv
pero percibo claramente
al capitán Vangeance en él.
pero percibo claramente
al capitán Vangeance en él.
mais je ressens clairement
ma percepisco senza alcun dubbio 
il comandante Vangeance dentro di lui.
mas eu consigo sentir o
Capitão Vangeance nele.
Но я чувствую,
что в нём заключена душа Вандженса.
