Larcei

Larcei is a playable character from Fire Emblem: Genealogy of the Holy War. She is the daughter of Ayra and the twin sister of Ulster.

After Seliph's army defeats the Grannvale Empire, Larcei will follow her lover to the destination of his choice. If she does not have a lover, Larcei will return to Isaach instead. She may ascend the throne, provided that both Shannan and Ulster have fallen in battle. Her substitute character is Creidne.

Taking after her mother, Larcei is a slightly hot-headed person, who is prone to hyperactive-like tendencies at times. She harbors feelings for Shannan, whom she looks up to, both as a mentor and a caregiver. Iuchar and Iucharba, sons of Danann, also have crushes on her, and either one may join Seliph's army, depending on who Larcei persuades first.

Another point to note is that Larcei is among the few who believe Ayra is still alive after the Battle of Belhalla. A conversation she shares with her brother has her heatedly chastising him when he openly doubts the possibility of his mother's survival, swearing to locate her once the war ends.
