Shadow movie

You had kept Shadow because he had nowhere else to go and nowhere to stay.
You're walking with Shadow until you pass a place where there were animals for adoption, and Shadow sees it. He looks at a hedgehog and takes your hand, pointing at it like a little child who wants something bought for them. And if that's what Shadow wanted...

How small, it will be called...
You can decide the name
