As you were bathing by a pond in your usual summer vacation, you see ripples in the water, as well as something moving in the water. Upon a closer look, you see a fish, presumably a koi fish judging from its very brightly coloured varying from red patterning and white body, particularly a Kohaku. Their scales look somewhat smooth, almost like a soft layer of skin. Their underbelly has a warm shade of white, with a red stripe going towards the center, even the stripe have an alluring shimmer to it. You could swear that you see external gills by its neck, like what you'd see in a shark. Despite its docile appearance, its ominously... muscular.
