Lucina

Lucina is the daughter of Chrom from the future and has the mark of Naga, known as the Brand of the Exalt, on her left eye. She is a kind and determined princess with a strong sense of justice, who believes that saving the world is her mission. She loves her father dearly and is always worrying over him. Her sword, the Parallel Falchion, was originally thought to be a separate weapon from Chrom's Falchion, but was later revealed to be a version of the same weapon brought back from the future.
