Chapter 6 (Quartet Knights)

Bewitching Moon Plot (妖月の企み) is the 6th chapter of Tashiro Yumiya's Black Clover Side-Story: Quartet Knights.

Summary
Yami Sukehiro wonders what Karna Freese is talking about with her revenge of the Clover Kingdom. Asta agrees that Karna has to explain it so that everyone can understand it. Yuno says that that is not what Yami was talking about. Klaus Lunettes notices that the mages besides Karna are the Magic Knights that they lost contact with, and wonders if they are being controlled.

Karna then sends the Magic Knights under her control at the four, and the Magic Knights launch spells at the four. Klaus thinks that it is impossible that the mages can still use magic while being controlled. Klaus tells the others to leave everything to him and uses Steel Castle's Armored Wall to block the incoming spells. Klaus thinks about how much it takes to control a single person and that Karna is controlling an army of them, along with allowing them to use their magic. Klaus then wonders just who is this woman Karna. Karna uses Bewitching Moonlight on the four, and Klaus notices that the spell is weakening their mana. As more spells are launched at the four, Yuno and Asta manage to take care of the spells. Asta says that that kind of magic will not work on them and uses his sword to nullify the spell. Karna notices that Asta has dispelled her magic with Anti Magic and comments about how fascinating Asta is.

Yami appears behind Karna and tells her to not get ahead of herself. Yami attacks Karna, but Karna manages to block the attack. Karna uses Crescent Cut, but Yami manages to withstand the attack. Asta asks if his captain is alright, and Yami tells him to stop acting all formal with him. Yami thinks about how Karna's mana is different, along with her magic attribute, and wonders if she is really Karna. Yami recalls that Karna was looking for a place to call home and does not belong here. Yami says that they should go back to where the others are at.

Suddenly Yami is wounded with a Light Sword of Judgment, which shocks the others. The three rush to Yami's side, while Karna says that she has nothing to return to and will continue on her journey for her revenge. Karna also says that she will be accompanied with the Eye of the Midnight Sun. Licht, Vetto, and Fana appear on top of some pillars. Licht says that Karna is having fun and wants to join in.
