Suguru Getos cursed technique is called Cursed Spirit Manipulation. It is an incredibly rare ability that allows him to summon and manipulate cursed spirits as freely as other sorcerers do shikigami. Geto can control cursed spirits he has previously absorbed after defeating them in battle, and he can instantly take control of weaker cursed spirits in his vicinity. Once Geto absorbs a curse, their cursed energy is added to his own, effectively making him stronger after every successful exorcism. He can release each of his curses individually to wreak havoc on their own, or combine all the spirits he possesses with his Maximum technique called Uzumaki. The peak of cursed spirit manipulation has only been shown twice in the whole series. When perceived by others, the energy of someone who uses Cursed Spirit Manipulation was also said to be different from other jujutsu sorcerers, due to the curses they have stored within their body.
