This article is about a character in Higurashi no Naku Koro ni.

Frederica Bernkastel (フレデリカ・ベルンカステル Furederika Berunkasuteru) is a writer of poems that appear throughout the chapters of Higurashi no Naku Koro ni.


Frederica is not given an appearance in the original visual novels. When she appears in the secret ending of Matsuribayashi, she is assumed to look like an adult version of Rika Furude, which is carried across in various adaptations.

The manga version of Minagoroshi features her as looking the exact same as Rika with her dress but with an empty look in her eyes obscured by her hair.

"I am Frederica Bernkastel. I am a different person than Rika Furude. ...It might be better to call me a 'different personality.' Some call me 'witch.'"
— Frederica'self-introduction in the Minagoroshi manga


Frederica speaks very directly. She can be seen as the mature persona of Rika and thus has a different speech pattern, which is more apparent in the Japanese version: Frederica speaks with the pronoun "watashi" (私), a polite pronoun used by women as opposed to how Rika normally speaks with "boku" (僕), which is used by young kids in a humble manner.


In Minagoroshi, Frederica refers to herself as one of many Rika Furudes and says she was created when Rika lost interest in breaking her fate.[1]

In Saikoroshi, Frederica is created from Rika after she is sent to a new world and becomes aware of how desensitized she has become as a result of her journey through the Fragments. Rika calls herself a cruel witch and decides to name that cruel part of her personality Frederica Bernkastel, with "Frederica" derived from her own name ("Furude Rika" in katakana [フルデリカ] is one character off from "Frederica" [フレデリカ]) and "Bernkastel" derived from the Bernkastel brand of wine she was drinking. Interviews with Ryukishi07 add that Frederica is meant to be the amalgamation of every Rika that had died in her 100-year journey, comprising all of her memories and negative emotions.[2]

In any case, it is suggested all of Frederica's poems are actually written by Rika. Minagoroshi features Rika reciting a poem[3] that is later recited by Frederica in Matsuribayashi.



Frederica's poems preface many of the arcs.


Frederica Bernkastel makes her first proper appearance and speaks to the reader about the Rules X, Y and Z that affect Hinamizawa in every Fragment.

Rule X is where someone succumbs to paranoia because of Hinamizawa Syndrome and winds up turning violent, using Keiichi Maebara, Shion Sonozaki and Rena Ryuugu as the prime examples.

Rule Y is where Jirou Tomitake and Miyo Takano are killed on the night of the Watanagashi Festival, marking the fifth year of Oyashiro-sama's curse.

Rule Z is where everyone believes the Sonozaki family are responsible for carrying out the curse every year amongst other things, which makes it difficult to find the true answers otherwise.

The manga adaptation has Frederica appearing in physical form and conversing with Rika about these Rules.


Frederica speaks to the reader once more and tasks them with connecting Fragments and revealing the truth of everything that happened before June 1983.

In a secret Fragment, unlocked after redoing the Fragments section after finishing the story once, Frederica in adult form explores a Fragment where she meets a young Miyoko Tanashi and averts the situation that led to her parents being killed. Afterwards, Frederica continues to have fun exploring other Fragments.


  • Bernkastel from Umineko no Naku Koro ni is theorized to be the same character as Frederica due to their similar names. The side story Bernkastel's Letter even ends with a poem listing Frederica Bernkastel as the author. An interview with Ryukishi also suggests that he enjoyed making Rika evil in regards to Umineko.[2]
