Satoru Gojo's status as the strongest character in Jujutsu Kaisen makes him one of the most formidable opponents to encounter in battle, but his skill doesn't automatically translate into proficiency as a teacher. Part of Gojo's duties as a sorcerer includes preparing the younger generation to become sorcerers themselves, but the consensus among his students is that apart from combat lessons, Gojo is completely hopeless at teaching the finer points of jujutsu. In fact, until Gojo's battle with Sukuna, Yuta Okkotsu, Gojo's star pupil had never witnessed a proper practical demonstration of certain techniques.
