Yuki-Onna!
Okay, this may sound like a cheap shot at first, but let's look a little deeper into this Youkai, shall we? Yuki-Onna are said to be the spirits of people who perished in a snowstorm. They are icy cold and freeze people who touch them, and seem to be able to control blizzards and snowstorms to some degree - while at the same time lacking such control. Emotional bursts can cause them to lose control of their powers, freezing everything around them, and they can't "warm" themselves up which makes them rather unsuited for warm-blooded individuals. It's not that they're innately evil though.

So, let's look at Kopaka: more metal than flesh, and ice and snow are his thing. Yuki-Onna would not be able to accidentally freeze him during a hug, drain his lifeforce or turn him into an ice statue by being near him, and if ever she lost control of her powers in a public environment, Kopaka would be right there to prevent the snow from harming people. Similarly, Yuki-Onna's great powers complement Kopaka's control over ice if ever they got into battle.

Kopaka is more of a solitary type, but Yuki-Onna just might be the one to melt his heart with her friendly emotional self once she warms up to him a little. I could see them meeting somewhere in the frigid mountains, Yuki-Onna believes that he will be yet another victim turning to ice as she comes remotely close to him. She is solitary not by choice but because her powers make her hostile to all life. And yet Kopaka is unfazed by her curse - quite the opposite, it strengthens him. They can hold hands without his fingers turning blue, they can hug without him stopping to move forever... well, the kissing part may get a little difficult, but is that really a big problem?
