Frederica Bernkastel
She is hinted to be "Frederica Bernkastel" in Higurashi no Naku Koro ni. She is also known as the Witch of Miracles. Unlike other witches she has lifeless eyes. She appears to see Beatrice's game to solve her boredom, and unable to stand seeing the player getting tortured by Beatrice's game.
More about Fredrica, Fredrica is an omni-present being surrounding the Higurashi universe. Frederica is the writer of the poem about Rika's struggle to escape the fate of June 1983, giving hints about each arc. She likes playing with time and events, as seen in puzzle piece #52 and the end of the second season of the anime, entering an alternate world and stopping Miyoko's (Miyo Takano's) parents from dying. She even has an intention of making a world where Rika's or Satoko's parents did not die, or pairing Keiichi with various girls. Although she claims that she is not Rika, it's implied that she is the collective mentality of the several thousand reincarnations of Rika. The pronunciation of Frederica roughly resembles Furude Rika, and Bernkastel is well known for its wine. She is one of the witches in Umineko no Naku Koro ni.
