Rena

Rena is one of the central sisters in Regalia: The Three Sacred Stars and is closely tied to the humanoid machines known as Regalia. She lives with Queen Yui of Enastoria before their peaceful life is disrupted by attacks connected with the failed Rimgarde experiment.

Rena: motives, abilities, and relationships

Quiet, devoted, and protective, Rena appears younger than Yui but carries a dangerous history and power that she does not fully control alone. She can merge or synchronize with Yui to operate a Regalia, producing enormous strength, armor, energy attacks, and large-scale mechanical combat.

Rena's abilities and defining relationships

Yui is her beloved sister and partner, while Sara, Tia, and the other Regalia-linked girls reveal the shared origin and cost of their abilities.
