Ever since he was small, Izark was shunned by his mother, who called him a monster and rejected having given birth to him, which in turn results in the rest of his village shunning him as well. All that resulted in his insecurity about being the Sky Demon and does not easily trust others. Noriko was the first person to really open up to him, as she did not know of his being. He quickly comes to care for Noriko and the feeling soon turns into undeniable love but because he believes himself to be an abomination, he hides his feelings because he thinks he can only hurt Noriko.
