Kokichi Muta ( (むた) (こう) (きち) Muta Kōkichi?) is a supporting character in the Jujutsu Kaisen series. He was a second-year at Kyoto Jujutsu High using Ultimate Mechamaru as his proxy to attend school. Kokichi himself could not due to the sickly and fragile body he was born with as a result of his Heavenly Restriction.


Kokichi is a slim young man with light peach skin and sharp brown eyes. He had black hair tied into a top knot above his head and the majority of his body was obstructed by the bindings of his Heavenly Restriction. His entire body was scarred with grotesquely thin wrinkled skin that he dressed in bandages. His right forearm was missing entirely and both legs were too weak to support his weight beneath the knees. Immobile, Kokichi sat inside a bathtub attached to several tubes inside a remote cave.

Following his healing at the hands of Mahito's Idle Transfiguration, Kokichi obtained a healthy body. Only a single scar on his cheek remained and he was able to stand up on his own. Like his Mechamaru stand-in at school, Kokichi donned a normal jujutsu high uniform with a white puffy scarf-like cloth around the collar of it.


Kokichi was a reclusive and reserved individual who resented being born without a future outside of the jujutsu world. He proudly admitted he'd give back every ounce of cursed energy to gain a normal body.

Kokichi's dream of walking among his classmates in Kyoto.

Kokichi's resentment lead to him projecting on those undeserving. During the Goodwill Event, Panda suggested he and Mechamaru should get along since they're both cursed corpses. Kokichi took exception to this and thought of Panda as nothing more than just a doll.[3] This was because Panda got to live free in the sun while Kokichi was trapped inside, ill with his restriction.[4]

Around his classmates, Kokichi embraced the quiet robotic type persona while acting as a student through Mechamaru. He wanted to walk amongst them one day in spite of his condition and however they might have treated him.[5] Kokichi felt especially close to Kasumi Miwa, who confessed to sharing romantic feelings with.[6]

In order to achieve his dream, Kokichi was willing to engage in a Binding Vow with the enemy in order to gain a healthy body. He leaked information with them but included the conditions that they couldn't hurt his fellow Kyoto students in the contract. Kokichi attempted to kill Mahito and Pseudo-Geto after his body was healed. Fighting desperately to achieve his goal, Kokichi bet everything on his planning and determination. However, his desperation, unfortunately, lead to his demise before he could meet his classmates and Kasumi.[7]

Abilities and Powers

Overall Skill: Kokichi Muta was a semi-grade 1 jujutsu sorcerer while he was still a student at Jujutsu High. He could control several puppets at once remotely from a great distance, with each puppet possessing high combat abilities worthy enough to earn him his rank.

In order to defeat Mahito, Kokichi was prepared to unleash his entire life's worth of reserves of cursed energy to win. Pseudo-Geto acknowledged that Mahito's skill and strategies were exceptional in this battle.[8] It was nearly enough to exorcise the special grade curse or as Mahito puts it, Kokichi puts too much stock into his strategy. He was ultimately defeated because Mahito was able to lure him into a false sense of security after believing he had achieved his objective.[9]

Great Tactical Intellect: Kokichi was a highly tactical thinker and fighter who tried to always stay a step ahead of his opponent. While in combat with Panda, Kokichi ascertained Panda's strengths and weaknesses as well as his own at every stage of the fight.[10] Pseudo-Geto also praised Kokichi for having decent tactical prowess while fighting Mahito. Kokichi was well prepared for their fight and his tactics nearly succeeded in wearing Mahito out and damaging his body while neutralizing his technique.[8]

It can also be used to protect the cockpit from an enemy Domain Expansion. Technique Charge.png
