Okayu nyumu! R (Okayunyumu! R / おかゆにゅ～～む！R) is a romantic visual novel game featuring the VTuber Nekomata Okayu as its main heroine.

The story begins with an unusual encounter: one day, the protagonist meets a mysterious purple stray cat with beautiful fur but a clearly hungry appearance. Out of kindness, the protagonist shares an onigiri (rice ball) with it. However, the next morning, the protagonist wakes up to find not a cat, but a cat-eared girl sleeping peacefully in the same bed. She introduces herself as “Nekomata Okayu,” and with nowhere else to go, she begins living together with the protagonist.

As daily life unfolds, the two share quiet, warm moments—walking along familiar rural paths, visiting a nearby shrine, and going on ordinary shopping dates. Through these simple routines, their relationship gradually deepens into something between friendship and romance, filled with soft affection, humor, and gentle emotional development.

The game focuses on an immersive “you are the protagonist” experience, allowing players to freely set their own name and directly participate in the story. Through everyday interactions, players build a close bond with Okayu while slowly uncovering the mystery behind her true nature and hidden secrets.

A key feature of the game is its emphasis on exclusive content that can only be seen within this title, showcasing new sides of Okayu—her private expressions, unique behaviors, and intimate scenarios that reveal a more personal and unseen aspect of her character.

Overall, Okayu nyumu! R is a cozy romance visual novel centered on peaceful cohabitation, emotional bonding, and lighthearted daily life, blending warmth, mystery, and soft romantic progression into a gentle coming-of-age style narrative.
