Chapter 10 (Quartet Knights)

Twilight Vow (夕暮れの誓い) is the 10th chapter of Tashiro Yumiya's Black Clover Side-Story: Quartet Knights.

Summary
At the Black Bull base, Klaus has recovered and regained consciousness. He says that being knocked out while his comrades fought against the Eye of the Midnight Sun is his greatest failure. Mimosa tries to reassure Klaus that it couldn't be helped with how strong their opponents were. Mimosa then comments that Klaus has spent a few days asleep in the Black Bull base. Klaus tells her that they should be excusing themselves. Noelle notes the discrepancies between what they saw in the dungeon and the last time they encountered Vetto and Fana. Vanessa asks Yuno who Karna was being controlled by. Yuno replies that Karna told them that she's being controlled by her father. Vanessa wonders if Karna has also become young like Yami. Noelle notes that their captain was with them in the dungeon, and wonders if he and Karna walked into trap magic at the same time. Magna says that they have to stop Karna since she has joined forces with the Eye of the Midnight Sun to destroy the Clover Kingdom. Mimosa informs the others that they have contacted the Wizard King and await instructions. Noelle then asks if the others have collected any information. Charmy says she was eating, and Finral says he's out of mana. Magna wonders where Asta and Yami went. Luck doesn't know either, but he saw that Asta had followed after Yami. Lucks suggests that they might be fighting, but Magna says they wouldn't do such a thing.

Elsewhere, Yami is meditating on a rock when Asta (with Nero on his head) shows up. Asta says that Yami hasn't recovered yet, but Yami replies that Asta hasn't recovered either. Asta assures him that he's fine, and that this kind of pain is nothing to him. Yami calls Asta crazy, but then Asta asks what Yami is doing here. Yami replies that he was meditating due to all that's happened, but Asta asks what meditating is. Yami explains that it's a technique from his homeland that helps with calming the mind. Asta wonders if that's his thing now that he's young. Yami scolds him for not taking this seriously enough, then talks about how Karna is like family to him. Although Yami wants to bring her back no matter what, he admits that the Eye of the Midnight Sun is powerful and wonders if he'll be able to get Karna back from them. But then Yami notices Asta's face and asks what he's doing. Asta claims to be meditating; he's turned off his senses and entered a state of trance. Yami bursts out laughing and calls Asta an idiot, but Asta tells him to not say that even if he is an idiot. Asta says he doesn't understand difficult things either, but that they should try. He then declares that they'll bring Karna back, beat the Eye of the Midnight Sun, and restore Yami's body back to normal; and that everyone will help out because if Karna is Yami's family then they'll treat her like family too. Yami thinks to himself that his future self is lucky to have someone like Asta by his side. Meanwhile, Nero pecks Asta's head. Asta wonders if it was something he said, but startles when Yami draws his sword. Yami thanks Asta for his support and asks him to lend him his power. Asta pulls out his Demon-Dweller and crosses the sword with Yami's, agreeing to help.

Magna shows up on his broom and tells them that the Wizard King has contacted them for a strategy meeting, and they all go back to the base. Through a screen of communication magic, Julius Novachrono comments that Yami has truly become younger, and begins to ask him questions about it. However, Yami doesn't remember Julius and wonders who he is. Julius says they've conducted some research, but they should come to the capital so they can discuss the details. Julius warns that this is a serious matter: this will be a major battle for the fate of the Clover Kingdom.
