Yuvanta's peaceful history spans 2500 years. Since ancient times, an unsettling legend has been passed down in Yuvanta's history: on the day the four moons floating in the sky overlap, everything will return to its origin. Two Magenta Stones, possessing mysterious powers that have existed since the dawn of time, hold the answer to this legend. Kruger of the Deltas Empire, drawn by the power of these Magenta Stones, launches a large-scale invasion, targeting one Magenta Stone passed down through generations in the Kingdom of Ishtin. As a result of this incident, the Kingdom of Ishtin is destroyed along with its king. However, thanks to the king's swift action, Princess Adel narrowly escapes with a Magenta Stone, but is pursued by Massone, who steals her Magenta Stone and causes her airship to crash. Just then, Ryan, who was traveling with nomads to escape the war, discovers Adel and learns about the circumstances of the incident. He then realizes he is a member of the Shasan tribe, a descendant of the last warriors, and becomes enraged that the Deltas Empire harmed the Shasan tribe. To protect Yuvanta, he embarks on a journey with Adel to retrieve the Magenta Stone. Ryan gathers his best friend, Calip, and they infiltrate Governor Kruger's airship by plane to try and retrieve the stolen Magenta Stone, but paradoxically, Princess Adel becomes a hostage.
