Jujutsu Kaisen a Japanese manga series shows us Yuji Itadori and our world with ‘Curses’. Itadori is a school student having some not so ordinary physical strength. Due to some incidents, he sets off as a vessel of a cursed spirit, a very powerful one. This cursed spirit is Ryomen Sukuna, known as the king of curses.
Sukuna from Jujutsu Kaisen is actually based on the same-named spirit/person from Japanese legends, Ryomen Sukuna. He belonged to the Hida province in ancient Japan. He was described as a man of stupendous strength and was sharp-witted. He was a ferocious-looking beast, with two faces placed 180 degrees apart, no neck, a total of eight limbs. Each pair of hands and feet on the front and back of the body.
He used swords and bow narrows. One theory suggests that he was an enemy of the king and was a threat to humans. Thus, was slaughtered by the greatest shaman of that time. But other theories suggest that he was worshiped as a God and spread Buddhism. He was also considered as the founder of the Kyoto School in Jujutsu Kaisen.
Some theories suggest that Ryomen Sukuna was a great shounen 100 years ago. He was at a level similar to Satoru Gojo. He surpassed every limit in the shaman community. He started doubting everything about Shamans and curses. Then left their side and hence, the greatest shaman of that time tried to kill him, but couldn’t make it.
Thus, they spread his 20 limbs as cursed objects all over the world. These cursed objects contain not only his energy but his soul as well. These objects are gathering more and more energy with time and when Itadori ate one of them, they decided to make Itadori eat the rest of the parts and then kill him which will eventually kill the king of curses.
Sukuna from Jujutsu Kaisen has super-strength, super-reflexes, regeneration, durability, ability to heal his host, can create eyes, nose, and even heart. His cursed power hasn’t revealed yet, he can mimic other’s cursed power. He is immune to toxins. Sukuna domain expansion is called Fukukma Mizushi, this territorial expansion ability is different from other domain expansion techniques (construct and innate territory).
“It generates a shrine with a bunch of skulls scattered around it, it creates a bounding wall which increases hitting effective area with a maximum radius by 200m”. His cursed energy, Dismantle, is his default slashing attack, and the other is called cleave, it is flexible to targets’ roughness.
