With the arrival of the Augustinian Order in 1623, Magdalene served as an interpreter for the friars Francis of Jesus Terrero and Vincent of Saint Anthony Simoens.

Seeing so many apostatize, some time later, attired in her Augustinian habit, Magdalene turned herself into the authorities and declared herself a follower of Jesus Christ.

At age 23, she died on October 15, 1634, after thirteen days of torture, suffocated to death and suspended upside down in a pit of offal on a gibbet (tsurushi).

She was beatified by Pope John Paul II on February 18, 1981, in Manila, and canonized on October 18, 1987, at Vatican City among the 16 Martyrs of Japan.
