Deep within a corrupted forest that steals all life, a princess lies under a curse placed by a wicked dragon. This forest was once a normal place, but the princesss love destroyed the world and transformed it into a nightmare realm. Rega, the former captain of a knight order who was once a slave, ventures into this forest to battle the dragon and rescue Princess Lorana. His quest is driven by gratitude, as Lorana previously freed him from bondage. By his side travels a companion, a cat in leather boots named Pancha. Fueled by his devotion, Rega manages to defeat the mighty dragon. When the princess finally awakens and their eyes meet, Regas heart swells with joy, only for her to flash a sweet smile and whisper that he too has now been cursed.

This betrayal sets the stage for a dark fantasy journey where the knight must fight against the past, against powerful curses, and against the twisted nature of love itself. Rega is defined by his history as a former slave and his unwavering sense of duty, while Princess Lorana proves to be a deceptive figure whose actions have already doomed the world once. The narrative unfolds in a desolate, magical wilderness that responds to the princesss dormant power. As the story progresses, Rega must navigate this hostile environment while dealing with the implications of the curse placed upon him. Although the manga concluded its initial publication in early 2026, the creator has indicated that the story is only halfway through its journey, suggesting further developments to come.
