Type-moon, Do You Promise That Your Family Simulation Will Last Forever?

"We've discovered an ancient family." "Hmm." "This family has existed since the beginning of time, its members spanning from ancient times to the present. Among them are Anastasia, the last princess of the Tsarist Empire; Joan of Arc, the Patriarch of France; Murasaki Shikibu and Sei Shonagon, two great women of the Heian period; and Morgan le Fay, the Witch of Britain..." "Hmm—!?" "Besides that, we've discovered something else." "This family possesses a humanoid treasure passed down through generations—each generation forges a marriage relationship with these 'members.'" "???" ... In Type-Moon, I obtained a family simulator, allowing me to trace my past and add to my 'bloodline'—but in the end... I discovered... I'm the same person in every life? I've become the ancestor of this family?
