Rosa Joanna Farrell is a playable character in Final Fantasy IV and its sequel, Final Fantasy IV: The After Years. She hails from Baron, and is a skilled Archer and White Mage. Rosa is Cecil Harvey and Kain Highwind's childhood friend, and harbors romantic feelings for Cecil. Though Cecil is reluctant to let her follow him into danger at first, she stays by his side.
Rosa has blonde hair styled as a half updo with long bangs. She wears horned shoulder-pauldrons worn over a floor-length white and gold cape, a sleeveless white top with long, decorated gloves and a large belt that holds a dagger on her side. She wears a white pattern pantyhose, gold and pink knee braces and light purple ankle boots. She is said to be the most beautiful woman in Baron.
In Final Fantasy IV: The After Years, Rosa wears a long-sleeved and floor-length white gown with small horned pauldrons and a silver belt. She wears fingerless gloves, gray sandals, and a decorated pink and purple cape. Her hair is still styled as a half updo, but it is mostly concealed by her cape and she now has longer bangs framing her face.
Rosa is gentle and kind by nature. She is strong at heart, willing to follow Cecil into dangerous situations and stand by him despite his numerous objections. She also takes care of the other party members, encouraging Rydia when she is frightened and forgiving Kain without hesitation. Like Cecil, she is deeply concerned about Baron's aggression and wants to help warn the other nations. As Queen of Baron, Rosa continues to be a steadfast support for Cecil, while as a mother, she worries for Ceodore as he struggles to obtain his Proof of Knighthood and become as strong as his father.
Rosa is the Latin word for "rose". It is written identically in Italian, Portuguese, and Spanish. It is also an Italian and Spanish female name; the German, Norwegian, Swedish, Portuguese, Italian and Spanish word for "pink"; and the Bulgarian, Czech and Polish word for "dew".
"Joanna" is a derivation of the Hebrew name יוֹחַנָּה, Yōḥannā, which means "YHWH is gracious". Rosa's middle name is only revealed in the novelization of the game. According to the novel, Rosa takes the name from her mother, Joanna Farrell. Rosa becoming a queen with this name may also be an oblique homage to Queen Jayne, as both Joanna and Jayne are alternative derivations of the same Hebrew name; English Ja(y)ne is in fact directly derived from Latin Jo(h)anna via French Jeanne.
"Farrell" is an Irish surname that is the anglicized form of the Irish Gaelic name Ó Fearghaill, which means "a person of great courage" or "heroic".
