The Secret of the Mystery Painting, 'The First Supper'

For 2000 years, the clan of Judas Iscariot, betrayer of Jesus Christ, have searched for the whereabouts of Christ's legacy, but have been unable to solve the mystery. The current descendant, Nova, has succeeded in inventing an eye medicine that gives one the power to see through anything. She gives it to Zenigata, and stirs him up by telling him that Lupin will only interfere with their getting married. Zenigata goes all out for love, but Nova's objective is the half of the mystery painting, "The First Supper, " painted by Christ, that is in Lupin's possession, having been stolen by Lupin I. The painting has a map concealed within it showing the location of Christ's treasure.
