Floating on a calm sea lies a small paradise for cats—"Cat Island."

Drawn to this mysterious island, college student Makoto Shiramizu arrives from the outside world in pursuit of its mysteries.

The player takes on the role of a white cat living on Cat Island, using feline abilities—sneaking into narrow spaces, nimbly climbing to high places, and more—to assist Makoto in his investigation.

What is the mystery hidden on Cat Island that Makoto is pursuing?

Why not step into this heartwarming yet somewhat melancholic 3D exploration adventure?
