Parasite Black: Grim Days -
Karak, a Wei orphan adopted into the noble Lupinegar household, has spent his life sworn to protect Renia — heir to Gerano and the last hope of her fading house.
When the Demorai invasion reduces their city to ash, Renia refuses to accept defeat. Driven by legacy, bloodline, and a promise carved into her very identity, she sets her sights on a forbidden relic — a weapon whispered to restore what was lost.
But power does not come freely.
As Renia’s dream begins to consume her, loyalty twists into something far more dangerous. And Karak — hiding a truth even he barely understands — must decide whether devotion means standing beside her… or standing against her.
In a world devoured by war, what is more dangerous:
the enemy at the gates — or the dream that refuses to die?
