In the world of Solo Leveling, Shadows play a big role. They start off as undead beings created through a special ability called Shadow Extraction.
This ability lets someone turn a defeated enemy, like a monster or another person, into a Shadow. But there’s a catch: you can only turn someone weaker than you into a Shadow.
How Do Shadows Work?

Once turned into a Shadow, these beings serve the person who created them. Interestingly, the stronger a Shadow is, the more personality it has.
For example, Beru, one of the most powerful Shadows, even enjoys Korean dramas in his downtime, showing they can have unique interests and traits.
Growing Stronger
Shadows aren’t just stuck with the strength they start with, they can get stronger by defeating more enemies.
Plus, they’re super sneaky, being nearly invisible when hiding in someone’s shadow. There’s also a difference between Shadows made from beasts and those made from humans.
Beast Shadows aren’t affected by a magical item called the Cup of Reincarnation, but human Shadows revert to their original selves, forgetting their time as Shadows, if they come into contact with it.

Why Shadows Matter in the Story?
Shadows aren’t just cool, they’re crucial to the story, especially for Sung Jin-Woo, the main character who becomes the Shadow Monarch.
This means he commands a bunch of powerful Shadows. This setup adds an interesting twist to the story since characters who die can return as Shadows, giving them a second chance to shine in a new way.
