Furniture and Demons
In Umineko ‘furniture’ is defined as a being that is not considered human. The three servants (Genji, Shannon and Kanon) are not listed here, as they have more of a complex of believing they are furniture rather than actually being furniture (the entire laser sword and magic barrier stuff – never happened). They do count to the “no more than 18” limit and should be considered human, despite what they say otherwise.
