Juan Crisostomo IbarraThe Hero of Noli Me Tangere and El Filibusterismo. He is a mestizo (Filipino with mixed foreign blood, in this case Spanish) who studied abroad in Europe for the past seven years and returns to the Philippines to visit his late father's funeral. A certified Wide-Eyed Idealist... until secrets are revealed and things promptly go to hell.
Padre DamasoA rude Spanish friar who was also a family friend of the Ibarra family. Key word being was, since Damaso definitely hated the guts of the Ibarra patriarch, Don Rafael Ibarra — Crisostomo Ibarra's father, and was not afraid to hide it. This hatred extends to Crisostomo, whom Damaso despises for studying abroad and thus being enlightened enough to understand the Spanish oppression. Padre Damaso bears a grudge against Filipinos (who they called indios during those times) and was once the parish priest in Ibarra's hometown, before he reassigned to another town by the Governor General because of something Damaso did.
Padre SalviPadre Damaso's successor as the parish priest of San Diego, Ibarra's hometown. Unlike the loud and rough Damaso, Salvi is quiet and sickly... but that doesn't mean he's any better than the former. Padre Salvi is often the one who makes decisions for the town of San Diego, something which irks actual town officials. He is bitter enemies with the alferez though they pretend as though they were not in public. He is implied to be the one who killed Crispin. Oh, and he also has his eyes on Maria Clara.
Maria ClaraIbarra's childhood friend and fiancee. A sweet and caring young lady, Maria Clara is the only daughter of Kapitan Tiago and Pia Alba.
Kapitan TiagoThe good captain, Don Rafael's good friend, and Ibarra's future father-in-law or was supposed to be. His kind heart is overridden by the fact that he's too weak-willed to fight back against the Spanish, whom he is loyal to.
SisaA loving mother of two boys, Basilio and Crispin. Also a loving wife of a gambler. She tries to make ends meet by sewing and selling homegrown vegetables, but her husband's habits and her children's workplace kind of obstruct her goals and dreams. This being a Crapsack World, Sisa loses two of her children (Basilio goes missing and Crispin presumably winds up dead) and subsequently goes insane.
BasilioA ten-year old sacristan at the parish of San Diego, he is the oldest of Sisa's two children, making him Crispin's elder brother. He tries to make ends meet by working as a sacristan at church alongside his brother. Unfortunately, church work is most probably the least rewarding job at the time, and he and Crispin end up being accused of stealing from the church collection. One night, they are confronted by the sacristan mayor and the parish priest. Crispin is captured and tortured while Basilio manages to escape by slipping down the ropes of the church bells.
CrispinA seven-year old sacristan at the parish of San Diego, he is the youngest of Sisa's two children, making him Basilio's younger brother. He tries to make ends meet by working as a sacristan at church alongside his brother. Unfortunately, church work is most probably the least rewarding job at the time, and he and Basilio (mostly Crispin, though) end up being accused of stealing from the church collection. One night, they are confronted by the sacristan mayor and the parish priest. Crispin is captured and presumably killed during interrogation while Basilio escapes by slipping down the ropes of the church bells. From what is seen during interactions with his brother, Crispin is the more idealistic and hopeful person between the two.
