There has been a popular rumor within a small village neighboring an abandoned kingdom... It is said that the kingdom's princess had been locked in the tower for her own safety during its downfall, and has since been trapped there for the past 73 months. A hero came each month, yet none returned. People believe the tower was filled with monsters and traps, making it impossible for anyone to save the princess...

Silver, who had been working as a wandering knight for experience, heard of this rumor felt sympathetic towards the princess he had never met. It didn't take long for him to decide he should try saving the princess despite all odds. So, the knight packed his bags and ventured into the kingdom, standing at the bottom entrance of the imposingly tall tower.
