小粥 莉瑠

The younger of the Okayu sisters.
She is hot-headed, and often hides her true feelings.

To outsiders, she puts up a serious and polite, if somewhat snide, front. However, in reality, this is simply posturing, since she is actually quite spoiled and lazy.

Partially due to her elder sister, Seira, she is fairly knowledgeable about sex. However, unlike her sister, she is not socially awkward, and so does not make this part of herself readily known.

She began cosplaying initially by simply tagging along with her sister, but is now a cosplayer in her own right, working under the pseudonym "Rieto".  

As opposed to her sister, the thing she enjoys about cosplay is the way she can freely express herself and act how she really wants.

She cosplays as the character "Riruru" from the erotic, isekai, harem, fantasy manga the protagonist publishes, "Torotoro Evoking".
