Is this?

C'mon. Just one pic?
My guess from what you provide is Hariwake.

 

[Jimmy16]

I think you're right

I’m kinda leaning towards shusui. It looks like it has a zipper line down the dorsal.
It could very well be a mix of the two. Shusui x Hariwake
It’s a cutie either way
Also, a top view picture for a koi Id is always a plus.
