DanMachi - Is It Wrong to Try to Pick Up Girls in a Dungeon? - Season 4 - Volume 2 - Blu-ray (German)

"The Hestia Familia receives an expedition mission from the guild that takes them to the deeper levels of the dungeon. Not entirely without danger, after all, there are far greater dangers and more brutal monsters lurking there than on the levels that Bell and his friends already know. You need strong allies to accompany you on this expedition and a lot of preparation. It soon becomes clear that all the hard work is sorely necessary and Cassandra's premonitions fuel this suspicion. The Hestia Familia and her companions get caught up in a whirlwind of hair-raising battles with extremely powerful monsters, a strange murder case and a massive hunt. In addition, things seem to be happening in the depths of the dungeon that once had to do with the extinction of an entire Familia...? The fourth season is bursting with events and transformations - so it's no surprise that it has 22 episodes!"
