Meta-World

Purgatorio, also known as the Meta-World, is a secondary dimension in, separate from physical reality. Purgatorio is seen as the witch's realm and is where the "games" of Umineko no Naku Koro ni take place. Any fragment of reality may be viewed from Purgatorio. It is implied that Purgatorio is some kind of afterlife.

Most of the debating between Beatrice and Battler take place in the Witches Smoking Room, an otherworldly room within Purgatorio.

Purgatorio seemingly appears in, specifically in. In the opening scene of Minagoroshi-hen, Rika Furude is seen examining several different fragments in a Purgatorio-esque place before finally entering one.

In Ougon Musou Kyoku, either team may attempt to enter Purgatorio for significant advantages and powerful moves.
