Hinayama, Rio

雛山理緒

Rio possesses a bright, cheerful, and childlike personality. Although she appears younger than Akari and Hiroyuki, they are all actually the same age. A defining trait is her terror of dogs, despite the fact that dogs seem to really like her.
Rio has a paper route that covers Hiroyuki's neighborhood, but she has actually known him for some time (even though Hiroyuki, as always, doesn't remember).
