Rika and Hanyū
Rika
Rika is the main character in Minagoroshi-hen. She is a younger classmate in Keiichi's school, and is in the same grade level as Satoko. Naturally, she is great friends with her, as they live together in the same house. She is revered by the villagers as the heir of the local shrine, and plays the role of a miko in the annual Watanagashi Festival. She has been the head of the Furude house since her parents died, but rarely attends town meetings due to her young age. While she does speak in normal context, she likes to say nonsense words such as mii (みぃ〜?) and nipa (にぱ〜?) and often ends her sentences with nano desu (〜なのです?, lit. "it is so"), which inflame Rena's passion for cute things. She also likes to describe events using sound effects, such as "The cat was going 'nya nya' and 'scritch scritch'" or saying "Clap! Clap! Clap!" when clapping her hands. In fact, she is one of the main components of the eternally repeating June 1983, and is the only one who is consistently able to remember the past repetitions. She believes she has lived over 100 years by the time of Tsumihoroboshi-hen, but continues to act like a child in order not to alarm her friends. Prior to Matsuribayashi-hen, she is the only one able to see Hanyū, who has been an "imaginary friend" to her all her life. Despite her young appearance, she seems to be quite fond of wine, as well as kimchi, which she uses to silence Hanyū when Rika is in a bad mood; this works because both Hanyū and Rika's senses are linked together, though this seems to be redundant by Matsuribayashi-hen, possibly because of Hanyū's coming into the world. The wine she drinks is hinted to be Bernkastel vintage.
Hanyū
Hanyū is the mysterious "transfer student" in Matsuribayashi-hen. 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 Matsuribayashi-hen and Miotsukushi-hen did she gain the power to interact with others. Like many of the characters, she can be frightening when angered, and with her spirit-like nature, her appearance can change with her mood until she takes a physical form. She is the one responsible for the eternally repeating June 1983, which she created in order to save Rika from being murdered. 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 dislikes alcohol and kimchi, which Rika imbibes in large amounts as punishment when she finds Hanyū annoying (as both Hanyū's and Rika's senses are linked together). She mentions that she is a "being above man" 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 Shion's chat with Rika in Meakashi-hen) but does not personally think of her as Oyashiro; instead, she sees her as a close friend.
