Jerome wears a white and blue striped collared coat with blue pants and white shoes. He has blue-gray colored hair, brown eyes, and wears orange-tinted glasses.
Jerome tends to not agree with or understand his actions and more than willing to see the Shadow Angels destroyed and humanity prospering in their defeat. At the end of the series, when Commander Fudou was missing, he heroically planned the operation to Atlandia, deciding to disobey to his order and help Apollo and his friends to save Silvia in Episode 23, Fleeting Wings.
