The Northern Demon King's Adventure in the Human World

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

"Who are you?"

Shunaelle, the Demon King of the North, becomes intrigued by the woman who has been haunting her dreams for three years and begins searching for her.

The woman's true identity? A fragment of Shunaelle's soul that was cast into the human world.

Just as Shunaelle is about to reclaim the fragment, who had given up on life and returned to being a mere piece of the soul...

"I don't want to be absorbed!"

The fragment pleads with her, asking her to live the life filled with regrets in her place if she truly wishes to regain the lost piece of her soul.
