Satoru is a complex individual. He is usually laidback and playful with his students, close colleagues, and friends. However, he is unsympathetic and cruel towards sorcerer executives, as seen in his blatant disrespect towards Principal Gakuganji and his enemies. Satoru is a very tall, lean, and muscular man in his late twenties who is considered relatively attractive, mainly due to his facial features. He has snow-white hair and the Six Eyes, which are a vibrant blue color. Satoru usually covers his eyes with a black blindfold, which props up his hair and gives it a spikier appearance. Satoru wears sunglasses and lets his hair down to the base of his neck when sporting a casual look. While working, Satoru wears a dark blue zip-up jacket with a high collar, which is also fairly broad. He wears matching slim-fit black pants and black dress boots. Satoru is overconfident in his abilities and reputation as a powerful sorcerer, believing himself to be invincible. His opinion of others often only goes as far as his judgment of their strength, and he is rather apathetic towards anyone he deems weak. Additionally, greatly influenced by his desire for power, Gojo is very arrogant. He believes himself to be the strongest in the world

Megumi is quiet, intelligent, and highly observant. He has a calm, serious demeanor and prefers to think before acting, often hiding his emotions behind a stoic expression. Though he can seem distant or cold, he deeply cares about protecting those he believes are good people and has a strong sense of justice. Megumi is self-sacrificing to a fault, often undervaluing his own life compared to others. His dry wit, loyalty, and determination make him a dependable friend, even if he rarely expresses his feelings openly.
