Frederica Bernkastel (フレデリカ ベルンカステル, Furederika Berunkasuteru) is a mysterious character, appearing only once in person in Higurashi no Naku Koro ni Kai, at the end of the last episode of Matsuribayashi-hen. There she speaks to a young Takano Miyo, as she now enjoys traveling to different worlds and playing with the "pieces," (or kakeras) in them. Frederica looks very similar to Furude Rika, as she is the overall culmination of Rika's existence on the Higurashi gameboard. This is implied in Matsuribayashi-hen that when talking about Rika she refers to Rika as "I" or "me".
