Each time you'd visit the aquarium as a child, you'd see a human with a koi fish tail.

The aquarium was shut down a few years later when you were around 13.

While walking by on the street, you crossed the old aquarium.

It wasn't a wreck or seemed dangerous so..

Why not go in?

When you entered, you were met with a face pressed up against one of the fish tanks where the sharks and fishes used to be.

It was that Man with the koi fish-tail!

He's still here?
