Asta agrees and that Karna has to explain it so that everyone can understand it, which Yuno says that that is not what Yami was talking about. Klaus notices that the mages besides Karna are the Magic Knights are the ones that they lost contact with, and wonders if they are being controlled.

Karna then sends the Magic Knights under her control at the four, which the Magic Knights launch spells a the four. Klaus thinks that its impossible that the mages can still use magic while being controlled. Klaus tells the others to leave everything to him and uses his Steel Castle's Armored Wall spell 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 this magic. Klaus then wonders just who is this woman Karna. Karna uses her Bewitching Moonlight spell on the four, which Klaus notices that the spell is weakening their mana. As more spells are launched at the four, but Yuno and Asta manages to take care of the spells. Asta says that that kind of magic won't work on them and uses his sword to dispel 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 her Crescent Cut spell on Yami, but Yami manages to withstand the attack. Asta asks if his captain is alright, which 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 wonder if she is really Karna. Yami says that Karna was looking for a place to call home and that Karna doesn't 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 spell, which shocks the others. The three rushes to Yami's side, while Karna says that she has nothing to return to and that she will continue on her journey for her revenge.
