Byron is a middle-aged man, with golden eyes and dark brown, spiky hair, kept under a baggy beanie. He also has a pair of red sunglasses on his head.
He has a small goatee. Byron sports a beige shirt, that resembles a Hawaiian shirt, with floral patterns on the collar. He was also seen using a similar shirt, but with circular patterns. He keeps his shirt opened, revealing his hairy chest and muscular body. He dons a pair of shorts and straw sandals.
Genius intellect: Byron's genius is the main reason why he achieved the position of chairman. Although proficient in combat skills, his true prowess is strategizing and quickly adapting to any battle situation.
Byron's "Sakura-chan" is a seamless Hatsu ability. Whilst simple in concept, its execution requires enormous skill in Nen. He summons a teenage girl, which he refers to as "Sakura-chan", dressed in a schoolgirl outfit. Sakura can do a variety of tasks when commanded by Byron, although she does possess a temper that may lead to refusal. As stated by him, these tantrums are most likely caused by "a lack of perfect control over [his] aura". In most cases, she can be seen helping with paperwork and organisation around his office. In severe situations, she is summoned for help in battle, and the two perform a series of coordinated attacks capable of making the toughest of opponents struggle.
