Luce has blue hair and wears a yellow rain jacket, which is colored in reference to the flag of the Vatican City as well as a symbol for "journeying through life's storms". She carries a pilgrim's staff, which represents "the pilgrimage toward eternity", and wears mud-stained boots to represent "a long and difficult journey". Her eyes have highlights in the shape of a scallop shell, a traditional symbol of Catholic pilgrimage, as shells were used in place of a chalice before they were common.
