“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.
the Eye of the Midnight Sun
كل ما فعلته عين شمس منتصف الليل
Die Rache an den Menschen und
die Erweckung der Elfen durch das Kalte Auge
Él único objetivo de Ojo de la Noche
Blanca era restaurar a los elfos
El objetivo de Ojo de la Noche Blanca
era restaurar a los elfos
C’est lui qui, 500 ans auparavant,
avait entièrement élaboré
Le azioni dell'Occhio magico della notte bianca,
finalizzate al riportare in vita gli elfi
O Olho do Sol da Meia-Noite
Месть людям и воскрешение эльфов —
он боролся только ради этого.
