Someone tell that white cat he's not welcome here...

I've seen that black cat before somewhere, it's not the Ghost Trick cat but I don't know where it's from either.
The shape of the eyes is the main thing that differs.

Stupid cat accessories. I could SWEAR it was the Ghost Trick cat. But yeah, you're right. It's also missing the white inside the ears and yellow sclera.

Are you talking about Sakamoto-san ?
