A woman identical to me appears in my dreams, crying.

"Who are you?"

For three years, Shunaelle, the Demon King of the North, has been haunted by the same dream, growing curious about the woman and deciding to track her down.

The truth? She’s a fragment of Shunaelle’s soul, cast away into the human realm.

When Shunaelle tries to absorb the fragment back into herself, the woman resists.

『I don’t want to be absorbed!』

Instead, she makes a plea:
If you want me back, live my life—a life filled with regret—and make it right.
