One of the Younger Girls in Keiichi's Circle of Friends
This girl is one of Keiichi's younger classmates and is in the same grade level as Satoko. Rika is close friends with Satoko and the two live together at Rika's house. The last surviving member of the Furude family, Rika is the head of the family yet doesn't attend town meetings because of her very young age. The townsfolk revere her to be the next heir in line of the Furude shrine and she takes on the role of a priestess during Hinamizawa's annual summer festival. She has the habit of mixing nonsense words such as 'nipa' and 'mii' with her sentences and throws in sound effects when describing events.
Rika is also one of the major components behind the never-ending Summer of 1983 in Hinamizawa as each scenario she becomes involved in leads to her death and is able to retain her memories of each scenario that she got caught up in. She is the only one capable of seeing her "imaginary friend" Hanyuu and despite her young age, Rika shows a fondness of tasting wine which irritates Hanyuu since both of their senses are linked and would also get drunk.
