Chapter 267

The Devil-Binding Ritual (従魔の儀) is the 267th Page of Yūki Tabata's Black Clover.

Summary
After being summoned to the real world, the Anti Magic Devil says that he has not been in the physical world in a long time and takes on his true appearance. Asta proceeds to thank the devil for lending him power throughout all of his battles. The devil laughs at Asta and reminds him of the fact he took his right arm. However, Asta tells the devil that he is not bothered by his arm as it was a part of their deal. The devil laughs and calls Asta an idiot, which is why the devil wants to kill him. Asta recalls their first time meeting each other and criticizes the devil for calling him short as they are both the same height. He goes on about not wanting to get defeated by someone like that. The devil laughs at Asta and says he does not understand his situation. The devil then summons the Demon-Slayer Sword from Asta's grimoire and tells him that he will not win. The devil proceeds to attack Asta and proclaims that he will be taking all of Asta this time.

Asta tries to explain how he does not want to fight but Nacht insists that he does. Nacht reminds Asta that he is there to get stronger, and explains that if Asta loses, he will become a grotesque monster. Nacht points out that all the skulls in the chamber are of people who failed the ritual. Nacht tells Asta that he will put up there along with them should Asta lose. This prompts Asta to ask if the Devil-Binding Ritual is something forbidden, to which Nacht replies that they only have two days to train Asta to become stronger and that Asta would not have gotten stronger with decent methods.

The devil attacks Asta again, destroying one of the columns of skulls. Nacht tells Asta that the devil will kill him if he continues not to fight. Asta says that he read the devil's ki and can tell the devil is not trying to kill him. Nacht dismisses this claim and reminds him that his opponent is a devil who cannot have a good heart. The devil agrees with Nacht and says that all devils are scumbags. Asta senses that his devil is not like Zagred. The devil starts to attack Asta and once again claims that he will steal Asta's body. Asta anwers that just because he is a devil does not mean he is a bad person. Asta's words stun the devil and remind him of a woman saying those exact words.
