Regalia: The Three Sacred Stars - S01

In the kingdom of Rimgarde, two colossal robots engage in a battle so devastating it wipes out almost all human life 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, they bring unrest-and giant robots known as Regalia Gear. Their target is Rena, Yuinshiel's adopted sister. Rena is forced to expose her true nature: not just a pilot of Regalia Gear, but a "Regalia"-a human who can transform into a giant robot-and the one responsible for Rimgarde's destruction. Now entangled in a conflict that spans nations, Yuinshiel must safeguard her kingdom while shielding Rena from those who seek to exploit her power. Yet in defending Rena, she risks unleashing the same disaster that ravaged Rimgarde. As the two sisters face these impossible choices, their bond is tested like never before. Their fight is no longer just for their own survival-it's for the fate of the world.
