Entering the Dungeon

Accepting the Mission
A few hours earlier, Yami tells everyone about a discovered dungeon. Asta asks what a dungeon is, after which Magna, Rack, and Vanessa tell him what a dungeon is. Yami reveals the location of the dungeon and how they have to work quickly. Asta volunteers, which Yami approves, as the Magic Emperor requested Asta for the mission. When Asta and the other leave, Vanessa asks whether they will be alright. Yami says that this mission will help them grow and that Rack is with them, commenting on how Rack has excellent sensory magic and would have been chosen by the other squads had his personality not been an issue.

Inside the Dungeon

Activating the Traps

Rack, however, senses other people and rushes off, leaving Asta and Noelle alone. Noelle is angry about it but is quickly caught by a high level plant trap. Asta frees her, but he then finds himself caught and cannot free himself. Asta, however, is saved by someone using wind magic.
