Man in Type-moon, Creates a Magic Family Lineage

"We have discovered one of the oldest families." "Yes." "This family has been around since the beginning of the world. Its members from ancient times to the present include Anastasia, the last princess of the Tsarist Empire, Joan of Arc, the protector of France, the two talented women of the Heian period, Murasaki Shikibu and Sei Shonagon, and the British witch Morgan le Fay..." "Yes--!?" "In addition, we have discovered something." "This family has a humanoid treasure that has been passed down to this day-each generation will enter into a marriage relationship with these 'members'." "???"... People in Type-Moon get the family simulation period and can trace back to the past to add bricks and tiles to their own 'bloodline'. But in the end. I found out...I have become the ancestor of this family?
