Summary
Yami and Asta manages to defeat Vetto, which Noelle says that they did it. Yami and Asta says that its not done and that they will finish this all at once. Asta and Yami charge at Vetto, which Rhya steps in front of them. Rhya says that he hates to say this, but it's over. Rhya says that their time is up, and uses a light spell to blind the Magic Knights. When they are able to see again, they notice that Rhya and Vetto has disappeared.

Yami notices that the dungeon is collapsing. Noelle says that the dungeon's full blown destruction has started, and that they will have to leave or they would be in troubled. Suddenly Noelle and Luck are captured by some sand. Yami and Asta attack the sand, which Yami comments about how he has defeated loads of them already. Noelle explains that sand is a sand magical worm that has no concept of death as long as their is sand. Yami hears this and comments about how annoying it is. Yami tells Asta that he will destroy everyone, much to Noelle's confusion. Yami says that its all broken anyway and starts cutting his way through with the others right behind him. Noelle says that they are all meatheads, which Luck says that he wants to do it too but Noelle tells him to act like an adult.

Elsewhere, Rhya and Vetto arrives at a location through a portal. Rhya tells Vetto that that was dangerous, and that they would have been in trouble if they had stayed there. Vetto is frustrated and says that he would forgive those humans. Vetto tells Rhya to not get carried away and that they would never lose to trash like them. Vetto then says that he would never be defeated by humans like Noelle and Yami, and that he will never forget this disgrace. Rhya thinks about how Vetto is losing his mind, and that their is no helping since this Vetto is a copy. Rhya then thinks about how the copy's strength is no where near the original one, but its alarming that the humans where able to fight him to this point and that they will have to be careful. Rhya finally thinks about how the humans should not get carried away with the magic that they stole from them, since their time is soon up. Rhya tells Vetto to rest for a bit to restore his mana. Rhya also says that Licht and Karna will be back soon and then they will enter the final stage.

Back at the sand dungeon, Asta and Yami break through the sand and escape the dungeon with each everyone. Yami tells Asta that he understand the Ki thing now, and that he knew about it but didn't understand it until now. Asta comments about how he had learned from Captain Yami, which Yami says that he is amazing. While Luck is berried in the sand, Noelle thinks about how she thought that she was going to die. Yami says that he will become even stronger, which Noelle wonders why Yami and Asta have some much energy. Luck says that the stone table was destroyed again and what they did was completely useless, which Asta asks why Luck can smile while saying that. Yami comments that the stone tablet was destroyed again and that maybe next time that succeed, which Asta comments about how they couldn't do anything. Noelle sees this and thinks about how Yami and Asta look happy.

Suddenly Asta's communication magic tool starts to ring and he pick it up. Yami asks what that is, which Noelle explains that the devise allow people to contact with people that are far away. Noelle wonders who is contacting Asta, which Asta says that Mimosa is calling him. Noelle is shocked by this, and wonders if Mimosa wants something secret from Asta. Noelle then realizes what could Mimosa want from Asta. Asta asks Mimosa what she wants, which Mimosa says that Asta needs to save Yuno. Asta asks what is happening at their location, Mimosa explains that they went to the snow dungeon and met Karna. Mimosa says that she manage to get away, but Yuno and Klaus are being controlled by Karna. Mimosa asks Asta to save Yuno and Klaus, and collapses. Asta asks where she and Yuno are at, but doesn't get an answer. When Mimosa doesn't answer, Asta continues to call out her name.
