Regalia: The Three Sacred Stars

Finished

レガリア The Three Sacred Stars

Twelve years ago, a mysterious calamity known as the "Rimgarde Incident" devastated a kingdom, caused by the appearance of giant robots called Regalia. In the present, Empress Yuinshiel Asteria rules the peaceful nation of Enastoria alongside her beloved younger sister, Rena.

Their tranquility shatters when survivors from Rimgarde arrive, seeking Rena. They reveal her true nature as a Regalia—a human who can transform into a giant mechanical weapon—and blame her for the past disaster. As enemies close in to exploit her power, Yuinshiel must fight to protect her sister and her country.

Caught in a growing international conflict, the two sisters find their bond tested to the limit. Yuinshiel's determination to shield Rena risks triggering a catastrophe on the same scale as the one that destroyed Rimgarde, forcing them to confront a destiny that threatens the entire world.
