Regalia: The Three Sacred Stars - S01

In the kingdom of Rimgarde, two colossal robots clash in a battle that wipes out most of humanity before vanishing without a trace. Twelve years later, Yuinshiel Asteria, the young empress of Enastoria, struggles to uphold her rule and keep her people’s trust. But when survivors from Rimgarde arrive in Enastoria, wielding massive machines known as Regalia Gear, they seek out Yuinshiel’s adopted sister, Rena. Forced into the open, Rena reveals she is not just a Regalia Gear pilot but a true "Regalia"-a human who can transform into a giant robot-and the one responsible for Rimgarde’s destruction. Now entangled in a global conflict, Yuinshiel must safeguard her nation while defending Rena from those who would exploit her power. Yet, by standing with her sister, she risks unleashing the same disaster that once ravaged Rimgarde. As tensions escalate, the two sisters test the strength of their bond, fighting not only for their own survival but for the fate of the world.
