In the world of Eienkyo, monstrous beings known as the Kyōshin, creatures born in darkness and pure malice, threaten to engulf the world into chaos as they have only 1 mission, to destroy everything. To combat their growing threat, warriors arose wielding the power of Kiryoku, the manifestation of one's own will and soul, sand as humanities last and only line of defense. These warriors are called Sentarii, each armed with a signature weapon called Shinketsu, forged using special materials and their own Kiryoku that makes them truly unique and only bend to their will.

To prepare the next generation of warriors, academies were established across the 5 continents. These schools act as training grounds where students can hone their abilities, master their Kiryoku and learn how to face the Kyōshin or any future threat that may arise. Each major academy rests in the capital of one of the 5 kingdoms.

Yet, hidden beneath centuries of peace and prosperity lies a dark secret that was long since buried. A secret that once shook the world to its core. A kingdom that was erased from all records. Even its own name was lost to time, now only known as The Forgotten Kingdom. It was said that this kingdom was of pure evil, ambitious, power-hungry, and bent on world domination. But were these stories truly real, or merely lies told by the victors during the Great War? Only time will tell which is true, as secrets..... can stay buried only for so long.

A new era of conflict, secrets and mysteries begins now!
