Last note of the Golden Witch/Tea Party
Summary
Beatrice, Ange Ushiromiya, Battler Ushiromiya, Bernkastel, Piece, and Lambdadelta discuss the nature of creation and agree that any sort of creative endeavor is made greater by being given restrictions. Lambdadelta ponders whether there was originally a seventh person alongside them who Piece erased and Piece confirms this. The others speculate who it could have been and Piece offers hints: the missing person is skilled with chopsticks, immensely proud of their reasoning abilities, and is self-proclaimed as a great detective. Nonetheless, none of the others are able to guess at the missing person's identity.
The group speculates on how many "pieces" had been lost in the creation of the Umineko no Naku Koro ni franchise. Using an inverse of her powers, Piece summons three of the lost pieces as a special present for the reader.
The first of these pieces is the original incarnation of the Goats. The second piece is a variation of Beatrice, bearing the appearance of Natsuhi Ushiromiya. This original version of Beatrice was rejected for being too "calm". Natsuhi-Beatrice acts out some of Beatrice's lines from previous stories and Piece summons the last piece. The third piece is Virgilius, a character whose purpose as a detective was eventually given to Erika Furudo and whose name was given to Virgilia. One of the few scenes Virgilius was originally in was transformed into the story arc of the man from 19 years ago.
Piece un-erases Erika Furudo's existence, who then guides everyone towards a tea party being hosted by Featherine Augustus Aurora. However, Lambdadelta and Bernkastel lag behind and claim they want to "take a peek" at "the next time something cries".
