Rie's Palace is an adult dating sim by LulluDev, made in Ren'Py and presented with animated 3DCG art. It follows a male protagonist whose relationship with his sister changes as they meet other people; over time, she grows distant and leaves him alone. Formerly called My Perfect Sister, the game focuses on sibling tension, new friendships, and emotional drift, with adult themes such as netorare.
The current build is v2.0, released May 17, 2024, and development is finished. It runs on Windows and Linux, in English, without censorship. The latest changelog entry, dated May 19, 2024, adds Part 1 v0.2.1b and marks v2.0 as completed. Earlier updates introduced new scenes, characters, costumes, a Maid Café system with tutorial and sound effects, and additional history/events.
