Picking up where the previous episode left off, Minori, Touya, Isuzu, Serara, and Rundelhaus are underneath their tent when Minori decides to tell the others that they should go to the dungeon in the afternoon. Although Rundelhaus disagrees, Minori points out that they only get two to three hours in the dungeon before they have to repeat, silencing him momentarily. She then goes on to say that she doesn't actually know any of them: what they liked, dislike, how their class worked; to prove her point, she asks Rundelhaus why he always used Orb of Lava. From there, each person began discussing their individual spells and capabilities. In the end, the team spent the entire day discussing strategies for fighting, which they would implement the next day.
