Vivian Uchechi Ogu was born on April 1, 1995, in Benin City, Nigeria, to Mr. and Mrs. Peter Ogu, becoming the second of four children in her family. She attended Air Force Nursery and Primary School, where she distinguished herself as an intelligent and diligent student. Vivian was an active member of St. Paul's Catholic Church on Airport Road in Benin City, participating in various church activities, including the Catholic Charismatic Renewal and the children's choir, where she served as choir mistress. At the age of nine, she was elected as the first president of the Holy Childhood Association in her parish, demonstrating early leadership and a deep commitment to her faith.

Vivian's dedication to her faith extended beyond her church involvement; she was passionate about missionary work and guiding her peers in spiritual matters. She organized fundraising efforts to assist underprivileged children in hospitals and frequently visited orphanages to provide support and companionship to orphans. Her peers and mentors recognized her as a light to others, always reaching out with advice and shared experiences to encourage maintaining purity and defending one's values.

Tragically, on November 15, 2009, at the age of 14, Vivian's life was cut short in a harrowing incident. That evening, armed robbers invaded her family home, robbing them of valuables and forcibly taking Vivian and her elder sister to a nearby bush. When the assailants attempted to assault them, Vivian courageously resisted, opting to face death rather than be defiled. Her steadfast faith and bravery led to her martyrdom, drawing parallels to saints like Maria Goretti, who similarly chose death over compromising their chastity.
