Riria is a busty girl that has the appearance of a Gyaru. This includes how she is dressed and wears a Gyaru-like makeup. She has her hair tied in twin tails.
Riria has a cheerful and rather laid back personality who also demonstrates a fair amount of mercy such as when she tried to persuade the Yuragi-sou residents who had feelings for Kogarashi Fuyuzora to abandon him so that they be spared.
Riria is in love with Nadare Tenko.
The two are subordinates that both serve and love Nadare Tenko. They are shown to get along with each other very well. When first introduce, they both are also shown to be competitive for Nadare's affections.
