Character from cradle-ghostwater by
The parasitic remnant bonded to Yerin — growing stronger with each battle, developing hints of independence that Yerin finds deeply unsettling.
The Blood Shadow is evolving. What began as a mindless parasite feeding on Yerin's madra has started to show flickers of intent — mimicking Yerin's sword techniques, reacting to threats before Yerin consciously notices them. It's not a person yet. But it's becoming something.
Crimson tendrils that extend from Yerin's back. The red lines across her skin have grown more pronounced since Sacred Valley. When Yerin fights, the Shadow moves with increasing coordination — less parasite, more partner.
