Xen is not your average Joe. In fact, he isn't even Joe. He just looks and acts like the newbie Hunter who died a horrible death in one of the many beginner dungeons that have littered the Earth since the System's arrival decades ago.

But what really lies beneath the human skinsuit once known as Joe is Xen the Mind Slime—a Shapeshifter.

Armed with the appearance and knowledge of the dead Hunter, Xen sets out to acquire new monstrous forms and abilities, all the while blending in with the other Hunters who seek to kill his own kind.

Think solo leveling but from a monster perspective.
