Description
Seimiya, granddaughter of Queen Halumiya and destined successor to the throne of the Divine Kingdom of Lyoza, tragically lost her parents in a traffic accident around age six. Raised solely by her grandmother, she developed a kind and gentle nature, initially seeming sheltered from her kingdom's harsh political realities. She holds deep affection for her cousin Damiya, whom she calls "Uncle," but possesses a strong aversion to conflict and warfare.

After Queen Halumiya's assassination, secretly orchestrated by Damiya, Seimiya ascends as the new Yojeh (True Ruler). She initially rejects peace overtures from Shunan, the Aluhan's eldest son, suspecting his family's involvement in her grandmother's death. However, Elin's revelation of Damiya's treachery and his role in the assassination forces Seimiya to confront the political manipulation she endured. This leads her to renounce her engagement to Damiya, recognizing his ambition to rule through her as a threat to Lyoza.

Seimiya's relationship with Shunan evolves significantly. Despite an initial mutual attraction, political tensions and Damiya's interference create distance. Facing imminent civil war between the Yojeh's Holon territory and the Aluhan's Wajak forces, and recognizing the need to prevent bloodshed, Seimiya accepts Shunan's marriage proposal. This pivotal act of political maturity unites Lyoza's two conflicting territories through altar diplomacy, sacrificing generations of enforced royal bloodline purity for the kingdom's stability. Her decision to raise a surrender flag during the confrontation at Tahai Azeh directly prevents large-scale battle, though it coincides with the Aluhan's assassination by his younger son, Nugan.

Seimiya's interactions with Elin transition from initial distrust to profound respect, especially after Elin exposes Damiya's crimes and provides crucial historical context about their shared heritage. Seimiya demonstrates her commitment by assuring Elin she won't be forced to use Royal Beasts in warfare.

Physically, Seimiya inherits the blonde hair that is a royal hallmark of her lineage. She is noted for wearing traditional robes and styling her hair in twintails. Her resemblance to the kingdom's founder, Jeh, is particularly emphasized in manga adaptations.
