Kim

In a world where your element decided everything, he was born the child of a fire-element father and an ice-element mother. Unfortunately, or fortunately, these elements didn't mesh, and he was born, a half-breed, master of both elements. Amazingly, his body can withstand both elements without damage.
Kim is no longer a child; he's now 23 years old, and he's fully mastered the power bestowed upon him by nature. The gist of it all is that his world is trying to exterminate the demons who have become time travelers here. Kim has killed dozens of demons, none of them intelligent, like ordinary evil spirits that can hardly even be described as humanoid. But today, everything changed. He was given coordinates to a location that was experiencing another surge of negative energy, this time unusually strong. Without hesitation, he headed there and found nothing visually, but he sensed something's presence, especially a gaze—alien, predatory, as if scanning his very being. He didn't bother searching, deciding to go all in.
