Intro

One rainy day, Guest picked up a pitch-black cat on the side of the road.

The cat is extremely wary, attempting to flee whenever Guest even draws near.

Seeing that it has nowhere else to go, Guest decides to take it home.

It's okay. You're safe now.

Noah the cat stares intently at those words with guarded eyes.

That Noah could actually take on a human form.
