Brás is a 32-year-old obituary writer for a Brazilian newspaper who dreams of publishing his own books. He lives under the intimidating shadow of his famous father, causing him anxiety about his own purpose and legacy. He constantly questions his life choices, striving to find passion and meaning in his everyday experiences as he moves through different stages of adulthood.

Benedito is an acclaimed, highly successful writer and a prominent cultural icon in Brazil. He often speaks in thoughtful aphorisms and spends long hours at his typewriter, chain-smoking cigarettes. Though he cares for his family, his intense focus on his work makes him somewhat emotionally elusive to his son.

Jorge is a jovial photojournalist and Brás's long-time best friend since their university days. He frequently travels with Brás around Brazil, offering a grounded, realistic perspective to counter his friend's constant daydreaming. As a man of color, he is acutely aware of the racial and social dynamics in their country, gently pointing out their status as passing strangers in the places they visit.

Ana is a working professional who builds a loving, stable life with Brás. She manages the demands of raising a child and maintaining an office job, often providing a practical anchor for her husband's more anxious tendencies. She cherishes the written notes Brás leaves for her and deeply values their family life together.

Aurora is the devoted mother of Brás and the backbone of the extended Domingos family. She works hard to look after everyone, especially when they gather at her family's rural ranch. She holds a special fondness for Brás because of the dramatic circumstances of his birth during a citywide blackout.

Olinda is a young woman from Salvador who becomes Brás's first serious girlfriend. She initially possesses an ethereal, siren-like quality, warning Brás that he might miss out on life by always rushing to the next destination. She harbors dreams of becoming a musician but struggles to find her footing.

Miguel is the young son of Brás and Ana. He looks up to his father as a hero and highly values the time they spend together, missing him terribly when work takes him away from home. He represents the continuation of the Domingos family line, stepping into the legacy left by his father and grandfather.

Iemanjá is a goddess of the sea from the Brazilian Candomblé religion. She appears as a mysterious, magical presence in Brás's recurring dreams. She functions as a spiritual guide, often presenting herself when Brás faces significant life choices and urging him to take an active role in his destiny before his opportunities sink away.
