Tears of Mary - Seeking the True Heart of the Mother

One winter day, Michio Fujiwara, a high school student, finds an oval-shaped medal beside a statue of the Blessed Mary at a church.
It is a "Miraculous Medal" of the Immaculate Mary. Fifteen years later, Michio has become a young and spirited artist, painter and sculptor.
He creates a replica of Michelangelo's Pieta that is unveiled at a ceremony to open the Museum of the Virgin Mary, and it wins him highest praise.
Two years later, however, the statue is vandalized by someone.
What is the purpose of destroying the Pieta?
Why does Mary in the Pieta keep shedding tears?
What was the true grief of Mary as she stood at the foot of Jesus' cross?
Mysterious incidents occur one after another in Kyoto and in Italy regarding the doctrine of the Immaculate Conception that hinders the unity of the Christian Church.
