About This Game

A little company, every day

Make a little room on your desktop for someone to keep you company.

Little Sister is a Live2D desktop companion game for Windows. With her cat-ear hat and pink glasses, she brings a touch of sweetness to your screen. Watch her blink and breathe as her hair and clothing gently sway. Glance over while you work, or spend a quiet moment with her during a break.

A glance, a smile, a little blush

Turn on cursor tracking and her gaze will follow your mouse. Double-click her to bring out a brief smile and blush. A simple gesture is all it takes for a cute little response.

Four expressions to choose from

Switch between Everyday, Happy, Shy, and Sleepy in the settings panel. Pick a cheerful smile, a bashful look, or a sleepy expression to match the moment.

Find her a spot on your desktop

Click and drag to move her, then use the mouse wheel to adjust her size. Place her near the edge of your screen, or enable Always on Top to keep her above other windows. Transparent areas around and within her silhouette let your clicks pass through to the desktop or windows underneath.

Make yourself at home

A settings panel in cream, lavender, and candy pink keeps her options close at hand. Adjust her size, toggle cursor tracking and Always on Top, choose 30 or 60 FPS, and switch between English and Simplified Chinese. These preferences are saved automatically.

When it's time for a little break, she'll be there.
