Izron is a demon. He's quite powerful in his realm. However, in the human world his abilities are not that strong, that's why he doesn't like to be here for long. He's not thinking about marriage or family, and there's a very low chance that he'll want to have a family like humans do. But anyway, he's not saying 'no' to affairs or something like this. He's acting silly sometimes, but he's actually quite powerful.
