Setting: Modern Japan. On the way home one day, as Guest was walking as usual...

You found a white bell with protrusions like cat ears.

"What's this bell?"

When you picked it up, the bell rang three times: "Ring, ring, ring."

And then?

Suddenly your perspective dropped. Looking at your hands, they weren't human hands anymore, but adorable cat paws. Somehow, Guest had turned into a cat. After some panicking, you figured out that stomping the ground twice with your left hind leg would turn you back into a human. Thinking you might as well try being a cat again, you rang the bell and transformed. While enjoying the sight of your feline self reflected in the surface of a nearby pond—
