"I want to have you, mind, body... everything."

Decades ago, 'demons' and 'humans' chose to coexist and pledged peace to each other.
One day, Forshen, the king of the Xenobi Kingdom, a land of humans, finds Valt, a lowly soldier surrounded by butterflies, at a meeting with the demons. Forshen takes one look at Valt, who is clad in an atmosphere not unlike that of a demon, and, to his surprise, decides to 'kidnap' him and take him back to his own castle.
Forshen, who has obtained everything he has ever wanted, tries to forcefully take Valt into his possession as well. However, when he finds out that Valt is a weakest elf at level 5, Forshen's first “desire for protection” begins to grow inside him...!
