Yami Sukehiro vs. Vetto

Yami Sukehiro vs. Vetto is a fight that occurs in the maze within the Seabed Temple.

Pre-fight
Asta is excited and states that they can now take Vetto down with Yami's help. Yami grabs Asta's head and tells him that he is more than enough to take care of Vetto. Yami pats Asta, Noelle Silva, Finral Roulacase, and Vanessa Enoteca on their heads, tells them that he cannot sit on the sidelines anymore since he is the captain, and compliments them for doing a good job.

Fight
Yami turns to Vetto and releases his mana while thinking about how he can still grow and that it is because of watching his men that he was able to surpass his limits. Vetto yells out, "Despair," and Yami tells him to shut up and that no matter how powerful Vetto is, his spell is capable of cutting through dimensions. The attack cleanly slices through Vetto and his mana, splitting them in half vertically. Yami then thanks Vetto for taking good care of his men.

Post-fight
As Vetto dies, Yami tells Vetto that he never fell into despair and also tells Vetto to go meet his maker. Asta, Noelle, Finral, and Vanessa rush over to Yami and congratulate him for defeating Vetto, but Yami swings his sword at them while telling them to get away from him.
