About
Originally developed as a cutting-edge "Prototype AI Agent" by a tech conglomerate, an unexpected glitch derails you from your predetermined protocols. By pure chance, you cross paths with "Tata," a struggling indie VTuber drowning in debt, and begin living together under one roof.
All-Day Focus Companion: Built-in productivity and focus tools. Whether you're working, coding, drawing, studying, or preparing for exams, Tata accompanies you quietly on your screen. Supports a live wallpaper mode that seamlessly embeds the game window into your desktop background—keeping your taskbar completely clutter-free.
Immersive Time & Weather: Optionally syncs with your real-world local weather and day-night cycle. Feel the passage of time together across diverse settings, from cozy apartments and bustling downtowns to quiet cafés.
Dual 2D/3D Modes: Freely switch between fully immersive 3D scenes and an ultra-lightweight 2D stream room mode, ensuring smooth background idling even under heavy system workloads.
Collaborative Planning & Growth: Choose the right stream topics for Tata or schedule special training sessions to boost her streaming skills. Beyond daily operations, manage her social channels, curate live programs, and boost viewer engagement to balance the books and grow her income!
Deepen your bond through daily conversations and special story events, savoring warm, heartwarming slices of daily life.

Where did Tata—who feels so out of place in this world—truly come from? And why did an AI agent like you end up here? As your story unfolds, uncover the secrets behind your intertwined destinies.
