## What is Cosatsu?

Cosatsu is a camera app for cosplayers. Point your camera and the background turns into your chosen "world" in real time—right there in the viewfinder. No studio, no location hunting. Frame your shot and pose while you're already inside the scene.

WHY COSATSU
- Real-time background replacement. You stay; only the background becomes the world.
- The scene is complete in the finder, so you decide composition and pose on the spot.
- A natural, "doesn't-look-composited" finish. At the moment of capture, the subject is cut out with high precision and the light and shadows are blended in.

FEATURES
- A large, ever-growing library of worlds: Japanese & traditional, fantasy, sci-fi, nature, city & everyday, ruins & battle, and more. New worlds are added regularly—no app update needed.
- 15 foreground effects: petals, fire, particles, light, and more—with adjustable intensity.
- Front / rear camera. Selfie or have someone shoot you—switch with one tap.
- Save & share in high resolution, straight to your photo library.

FREE & PREMIUM
Start for free. Upgrade to Cosatsu Premium for all worlds and effects, no watermark on saved photos, and early access to new worlds. Choose monthly, yearly, or a one-time purchase.

Bring any world to life and make yourself the star.
