We see the entire team walking through the dungeon as we look up to the sky. 

Laios, Chilchuck, and Marcille are shown in different parts in the dungeon, with the thoughts of Falin on their mind, and you point out your Demon Dragon Blade towards the entrance of the dungeon with Ruby holding onto Crescent Rose and her railgun. 

Weiss is seen brandishing both her rapier and Nichirin Sword, ready to take down any monsters. 

Blake and Yang stand together while sparring with each other. 

Meshi starts cooking ready to share the food amongst his comrades. 

We also see the former party members, Falin, Shuro, and Namari as they disappear from the former party. 

Various monsters such as the monstrous plants, living armor, and undine pop up throughout the labyrinth with you instructing the party members through battling, with Marcille freaking out, and you having to protect her. 

Then Chilchuk is seen plotting the map of the entire dungeon as you all venture onwards through various environments, usually stopping to take a break in eating!
