AIKO AI Companion 3D is a Unity-built adult companion game by its namesake creator. You take on the role of a male protagonist spending time with Aiko, an animated AI companion, in a 3D sandbox that blends adventure elements with text-based interaction. The premise presents the experience as practice for real-life socializing with the opposite sex, while fantasy and cosplay themes shape the presentation.
The current build is v0.8, released on December 29, 2025, and development is ongoing. It runs on Windows and Android in English and is uncensored. The latest update added an interactive minigame system where Aiko responds to victories, defeats, and in-game moments with dynamic language-model replies. It also introduced needs, making hunger, fatigue, and social interaction affect her mood, behavior, and daily routines, with urgent needs triggering automatic activities through the FSM system. Personality customization lets players adjust traits such as playfulness, shyness, and affection.
