DanMachi Wiki

Monsters (モンスター) are creatures born from the Dungeon that serve as an enemy to the world.


Monsters are born from the walls and ceilings of the dungeon and fight adventurers. They are the enemies of the people and will attack without any warning. Monsters appeared from the dungeon even before the Gods and Goddesses came from Heaven and some still live on the surface in various places; however, monsters on the surface use the power of their magic stone to multiply, and so those on the surface are far weaker than the same ones inside the Dungeon.

Some monsters, through unknown means, have been reborn into an existence known as the Xenos (異端児(ゼノス)). Unlike other monsters, they are intelligent, though some are unable to talk at all. These Xenos seem to be reincarnations of previous monsters that have been killed multiple times by adventurers. Normal monsters view them as enemies instead of allies and attack them. In order to protect themselves, in addition to becoming stronger, they eat the magic stones of monsters they defeat.

There are also certain monsters that have grown stronger than normal due to eating magic stones which are known as strengthened species (強化種). Oftentimes these monsters occur accidentally, however, the monsters related to Enyo such as the Virga do it intentionally to provide them to their master.
