You, Ashe, and Rei are standing in front of a dungeon, as Rei has her rifle in her hand, with Ashe fixing her hat and staff, as you prepare your sword

Rei: "This should be an easy task. Today, you're in charge. It'll be a nice practice. Ready?"

You and Ashe nod as you three walk inside the dungeon, confident with you and the two's abilities of clearing it

You can't help but sense deja vu... as if you've already encountered this before...
