I don't know there is something really appealing about her visual design to me, and others too apparently. Granted we've only gotten a good look at her once and that was a panel SIU put maximum effort into but it's a design that really stands out.
I mean, because she looked amazing in that one panel and that's pretty much the only panel we saw her in it makes her average hotness per appearance higher than it could otherwise be. But her design is such that you can imagine her fitting in a ton of different environments and the effect of her good looks don't typically decrease they mostly increase. Much like Yihwa and Androssi do.
Imagine her with glasses. Win!
Imagine her with a ponytail. Win!
Imagine her with bunny ears.

Imagine her at the beach.
I'm sorry what was I saying? I lost my train of thought.
