Chapter 198

The Five-Leaf Grimoire is the 198th Page of Yūki Tabata's Black Clover.

Summary
As Asta and Yuno manage to wound the Devil, the Devil uses his magic to heal his wound. The devil comments about how they were able to wound him, and describes Yuno as a half elf favor by the mana along with the power of the spirits while describing Asta as the owner of the grimoire that should have been his. The devil also says that he doesn't know what kind of Devil Asta is or where he came from, but he is going to hand that grimoire to him. Rades and Valtos are hiding close by and wonder what the Devil is. Rades also thinks about how Patolli was used by the Devil, just like how Patolli used them as pawns.

The Devil turns his attention to Patolli and explains how the five-leaf clover is born, while Patolli's four-leaf clover turns to a five-leaf one. As the five-leaf grimoire is now complete, the Devil says that he can now enter the real world since he has a body and a grimoire of darkness. The Devil explains how he was able to give birth to a grimoire 500 years ago but their was some resistance back then. The devil also explains how he had used to forbidden spell to reincarnate Patolli as his pawn, to obtain what he wanted. As the Devil grabs the grimoire, he comments about how it is simple to steal from a empty heart. The devil then comments about how much fun he had just to obtain what he wanted.

Asta and Yuno rush towards the Devil, which the Devil says that he is not their opponent. The devil explains what happens to an elf that his full of hate, while using his magic to turn Patolli into a Dark Elf. The devil then frees Patolli, who uses a spell to attacks Yuno and Asta. Yuno is cut when he tries to dodge, while Asta is pushed into the wall. Yuno thinks about how fast that attack was, but then asks if Asta is okay. Asta gets back up and says that he is okay, while thinking about how powerful that attack was and that he would be dead if his Anti-magic didn't eat away the magic first. As Asta thinks about how much stronger Patolli has gotten, the Devil comments about how Patolli is a heartless, soulless silhouette that they can have fun with.

The Devil decides to exit through the path above him and says his goodbye to the others. The Devil thinks about how this will be the end of Asta, and that he will have to go steal that body if he doesn't want to die. Asta thinks about how he can't let the Devil leave, and tell the Devil to wait. Suddenly Patolli appears before Asta and prepares to strike. Asta manages to deflect the strike, which Yuno uses this chance to attack with a spell. Patolli manages to dodge the spell and land a blow on Asta. 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 swings his sword, which Patolli dodges. Patolli gets angry and starts to release his mana, which Asta, Yami, and Nozel recognize what is happening.
