Summary
As Asta and Noelle are running down a hallway, Noelle thinks about how Asta is acting weird since Asta would normally what to help out his comrade. Noelle asks Asta about it, which Asta tells her that he believes in Yami. Asta also says that he has felt a bad Ki a while ago, and that Luck might have encountered the enemy. Asta then says that he believes in Yami and that they should go to where Luck is at. Asta says that they should head forward, which Noelle thinks about how Asta is still himself. Suddenly Asta sets off a trap and wonders why this has happened after he said all that stuff, which Noelle asks what has Asta done.

Back at the entrance, Yami tells the Sand Monster to let him go since there is no time. Suddenly the floor collapses, which Yami manages to land on the lower floor safely. Yami notices that there are more sand monsters and says that he will have to hurry and not make his comrades wait.

On the lower floors, Luck and Vetto clash. As they clash, Luck launches a Thunderclap Crumbling Orb at Vetto but Vetto easily counters it. Luck gets behind Vetto and attacks, but Vetto manages to reflect Luck away. Vetto comments about how Luck is so full of life, while Luck is excited about the fight. Luck then asks why Vetto is like the old version of him, and wonders if Vetto was restored with magic power since Vetto power and attack are so weak. Luck comments about how Vetto is boring, which Vetto gets angry. Vetto says that trash like Luck will not know, the despair that they cannot forget, and that humans deserve huge despair. The despair that the humans receive, will be like the despair that they have felt. Luck thinks about how even through Vetto is different, but how this is nonsense. Luck also thinks about how until now he did not win, but it is alright since he has changed. Luck also thinks about how he does not fight for himself anymore and that victory needs to be secured for his comrades. As Luck activated a spell, Vetto notices that Luck's magic has evolved. Luck then says that for now on, they will be fighting for real.
