古手羽入, Hainiryuun Ieasomuuru Jieda Oyashiro-sama
Hanyuu is the mysterious transfer student in Matsuribayashihen. She has a pair of dark colored horns on her head one of which is chipped slightly however no one seems to notice or mention them with the exception of Takano who calls her a monster. In fact she has appeared to Rika all her life but only in Matsuribayashihen and Miotsukushihen did she gain the power to interact with others posing as a distant relative of Rikas and given the name Hanyuu Furude. Like many of the characters she can be frightening when angered and with her spiritlike nature her appearance can change with her mood until she takes a physical form. She is very meek and often makes the noise Au au au au when she is nervous or uncomfortable or sometimes while trying to make a point. She also tends to end her sentences with nano desu ? lit. it is so. She dislikes alcohol and kimchi which Rika imbibes in large amounts as punishment when she finds Hany annoying as both Hanyuus and Rikas senses are linked together. She mentions that she is a being above humans after being sacrificed to atone for the sin of humans while both Rika and Takano describe her as a kind of deity. Rika refers to her as Oyashiro when talking with others evident from Shions chat with Rika in Meakashihen but does not personally think of her as Oyashiro instead she sees her as a close friend. In Higurashi no Naku Koro ni Rei Hanyuu tells Rika that she was sacrificed to atone for the sins of the people of the village and Hany asked Ouka Furude Hanyuus own daughter and Rikas ancestor to kill her and then make the village a better place.
