Black Clover Chapter 198

The true mastermind reveals that Patry's four-leaf grimoire has transformed into a five-leaf grimoire under deep despair, allowing the devil to claim its physical form and a black grimoire. As the overwhelming malice consumes Patry, he turns into a dark elf while a barrage of light swords devastates the surrounding area. Asta and Yuno barely survive the onslaught, protected only by their surging magic and anti-magic powers. Desperate to reach Patry, Asta tries to reason with the transformed elf, but Patry is completely consumed by hatred and anger.
