Summary
Fate is always a choice, even for a Demon King.
When Gwi-Ma’s existence can no longer sustain itself on stolen lives and hoarded memory, he is forced into rebirth as a human child—the very cycle he once defied as Demon King. Baby Saja is crowned in his place, much to everyone’s surprise. Becoming King, however, is not as simple as he thinks.
As one learns mercy as law and the other learns childhood as penance, the Saja Lords and the Huntrix must decide: how far will they go to keep their youngest from breaking under the weight of kingship, and to stop a child from becoming a monster again?
(This story is set in Gwima-gye, my original world. Gwima-gye is a demon realm shaped by Korean cosmology and xianxia, making it a xuanhuan world. If you’re new to this genre, I warmly invite you to give it a try.)
