Claude has short, golden hair with bangs sweeping over jewel blue eyes, an inherited trait from the imperial bloodline. He is tall with broad shoulders, long limbs, and a well-built figure. Claude has a very complex personality due to a series of tragic events that occurred throughout his lifetime. After his older brother's betrayal and Diana's death, Claude cast a spell using black magic to eradicate his emotions. Without his cumbersome feelings, Claude grew to become cold and stoic.
