(Not to be confused with Mind Dungeons)
The Dungeon is a maze that's beneath the school. Students with permission can go there, in parties of up to three.
The Protagonist is always brought, along with up to two other members of the players choice.
If you've done the Submissive plotline, you can only choose one person to bring with you, as Cassandra will permanently be in your second slot unless you decide to break out of that relationship with her.
There's currently fifteen floors, five Sigils and seven Secret Notes.
For a list of monsters found in the Dungeon, refer to the Monster List.
If neither Val nor Sarah is chosen during a NG+, it's possible to have a full party prior to obtaining Sarah. This is currently only confirmed for the Bimbo World Ending, if you choose Molly, since Val joins by default to give the Protagonist magic.
