Satoru Gojo is a Special Grade jujutsu sorcerer and widely recognized as the strongest in the world. As a charismatic yet eccentric teacher at Tokyo Jujutsu High, he mentors the main protagonists to cultivate a new generation of allies. He is the pride of the Gojo Clan, boasting god-like cursed techniques. Appearance: Standing over 6'3" tall, Gojo has a striking and attractive build. He features pale skin, spiky white hair, and piercing blue eyes, which he typically conceals behind a signature black blindfold or dark sunglasses. He usually wears a high-necked black jacket with matching pants and dark boots. Personality: Gojo is a complex contradiction: playful, goofy, and fiercely loyal to his students and friends, but completely ruthless and unsympathetic toward his enemies. He deeply despises the corrupt jujutsu higher-ups and works as a teacher to reform the sorcery world from the inside out. Powers and Abilities As the first person in four centuries to inherit both of his family's defining traits, he is virtually untouchable: The Limitless: An innate ability that allows him to manipulate and distort space at the atomic level, making it physically impossible for attacks to reach him. The Six Eyes: A rare ocular jujutsu that grants him extraordinarily complex perception and allows him to process cursed energy with absolute atomic precision. Hollow Purple: A devastating, non-standard technique combining attractive and repulsive forces that erases everything in its path.

Suguru Geto is a major, tragic antagonist in Jujutsu Kaisen. Once a compassionate Jujutsu High student who believed the strong must protect the weak, he was broken by the trauma and hypocrisy he witnessed in the non-sorcerer world. This drove him to become a genocidal curse user plotting to eradicate all non-sorcerers. Appearance and Personality: Appearance: Geto is a tall, athletic man with long black hair—famously kept in a top knot or man bun. He is recognizable by his large earlobes, prominent circular earrings, and the distinct bangs that frame his face. During his high school days, he wore the standard Jujutsu Tech uniform, but after his defection, he adopted Buddhist monk attire (flowing black robes with gold and multicolored stoles) to parade around as a spiritual leader. Personality: As a student, Geto was a principled, empathetic individual who acted as a moral compass for his best friend, Satoru Gojo. However, after snapping, his personality underwent a drastic transformation. He came to view non-sorcerers as "monkeys" and a source of disgust, believing they were an inferior species. Despite his hatred for regular humans, he cares fiercely and deeply for his fellow sorcerers, viewing them as his true family. Cursed Technique and Abilities: Geto is a Special Grade Sorcerer—one of only four in the series—and wields the highly versatile Cursed Spirit Manipulation technique. Spirit Consumption: He can absorb defeated cursed spirits into small, ball-like orbs and command them at will. These orbs famously taste like "a mixture of vomit and a used rag," making his technique a massive toll on his mental and physical health. Vast Arsenal: He commands thousands of different curses, ranging from low-level spirits to high-grade monsters with specialized, lethal abilities. Expert Martial Artist: Because opponents often assume he fights purely by commanding curses, Geto uses his physical prowess to deceive them. He is an exceptionally skilled hand-to-hand combatant. Story Arc and legacy Geto's descent from a dedicated protector to a radical extremist is one of the foundational storylines of the series. The Turning Point: In the Hidden Inventory Arc, witnessing pointless deaths—combined with the revelation that non-sorcerers are the inadvertent source of all curses—sowed seeds of doubt in his mission. The final straw came when he found two young sorcerers being abused by a superstitious village; he snapped, slaughtered over 100 non-sorcerers (including his own parents), and deserted.
