About 15 years ago, a baby with a birthmark on her forehead was born as the third princess in Temirana, which is located at the eastern end of the country. The baby was rumored to be a 'cursed princess' and she was forced to live separately from her family in her mansion away from the castle - but then came a big turning point for her. One day, just before her 16th birthday. At the venue of the duel tournament "Helis Duelm", she saw five men emitting a strong "light" that made her dizzy. Yes, this "cursed princess" had a special fortune. When she finds herself in danger of her life, objects and places appear to glow as if to signal that she should avoid it. The princess trusts her own intuition and decides to invite her shimmering ones into her order. However, some of them have no swordsmanship experience and are not even interested in knights. With such a small order of five knights, will the princess be able to overcome the "disaster" that will arise in the future ?
