yuze, 1girl, short hair, large breasts, red/purple eyes (There isn't much difference between both colors; play around with the shades a bit), hat, cleavage, red hair, brown horns, pointy ears, one-piece swimsuit, covered navel, highleg, white jacket, goggles, competition swimsuit, goggles around neck

There are some things that don't quite add up for me, and I think the AI doesn't fully grasp it without very specific details. This is one of those that will have an update in the future.

PD: The color of the horns isn't an issue; I just realized it too late after making the images and was too lazy to specify the horn color.
