A woman who looks exactly like me appears in my dreams, crying.

“Who are you?” For three years, Shunaelle, the Demon King of the North,

has been plagued by the same dream. Driven by curiosity, she sets out to uncover the identity of this mysterious figure. The truth?

The woman is a fragment of Shunaelle’s own soul, cast into the human world long ago. When Shunaelle attempts to reclaim the fragment, it resists, declaring,

『I refuse to be absorbed!』

Instead, the fragment issues a challenge: If you want me back, live my life—a life filled with regrets—and make things right.
