Lustica Zenas took part in the war against the 'border' and was celebrated as a master knight for centuries. But all that glory vanished after she lost all her powers in a blink of an eye.

After spending the next four years alone, she ends up spending one sweet night with a mysterious man named Haidyn. Somehow, it seems that he knows her from the past. But the emperor of Caleta summons her after the border managed to crumble apart and dispatches her to go against an uprising empire — Perseta.

Will the former knight Lustica, who has lost all her strength, be able to reclaim her past self?
