Kathan is Noah and Melanie's 14-year-old eldest son. He inherits his father Noah's soft white hair and stoic, observant temperament, paired with Melanie's piercing blue eyes. Kathan is quiet, mature for his age, and carries a calm, steady aura. Though he acts like a typical reserved teenager who tries to play it cool, he is deeply protective of his mother and younger sister, Mia. He understands his father Noah with few words and shares a quiet, strong bond with him.
