Chapter 198

The Five-Leaf Grimoire (五つ葉の) is the 198th Page of Yūki Tabata's Black Clover.

Summary
As Asta and Yuno manage to crack the devil's arm, the devil uses its Kotodama Magic to heal its wound. The devil is impressed that they were able to wound it, and comments on Yuno's power form an elf and a spirit and Asta's power from a devil. The devil does not recognize Asta's devil and is not concerned with taking back Licht's grimoire. Rades Spirito and Valtos are hiding inside a corridor into the chamber. Rades wonders what the black creature is and if it used Patolli how the elf used the humans in the Eye of the Midnight Sun.

The devil turns its attention back to Patolli and explains how a five-leaf clover is born, while Patolli's four-leaf clover turns to a five-leaf. With the five-leaf grimoire now complete, the devil plans to enter the real world and unleash its true form and power. The devil explains that after its failed attempt 500 years ago, it used the corrupting effect of forbidden Reincarnation Magic to make the process easier.

As the devil takes the grimoire, Asta and Yuno rush forward to stop the devil, but the devil says that it is not their opponent and tells Patolli to go on a rampage, freeing him from the iron spears. The elf, who has given into his hatred and despair, has turned into a dark elf. Patolli uses Demon Light Magic to attack Yuno and Asta. Yuno is cut when he tries to dodge, as the black light is faster. Asta is pushed back into a wall and survives due to his overflowing Anti Magic weakening the attack's power.

The devil decides to exit through the corridor in the ceiling. Asta tells the devil not to leave, but Patolli suddenly attacks, forcing Asta to deflect the strike. Yuno uses this chance to attack with Spirit Storm, but Patolli dodges the spell, throws swords at Yuno, and loops back to attack Asta again. While blocking the thrust, Asta tells Patolli that they might not forgive each other, but they are still able to understand each other. Asta also tells Patolli to get out of their way and pushes Patolli back with his sword. Patolli gets angry and starts to charging an attack, which Asta recognizes. Nozel Silva and Yami Sukehiro also recognize the magic as they make their way down to corridors to the eleventh chamber.
