Kokichi Fukami

Kokichi Fukami is a supporting character in the Jujutsu Kaisen: Resurrection series, he is an alternate version of the original Kokichi Muta from the Jujutsu Kaisen series. He is a second year student at ??? Jujutsu High and a Grade 1 Jujutsu Sorcerer.

Due to his Heavenly Restriction giving him a weak and fragile body with missing limbs, he could not physically attend Jujutsu High, which is why he used his Mechamaru model cursed corpses as his proxies in order to attend it. After his body was healed by Mahito during the Evening Festival of the Shibuya Incident, he is now able to use his own body to traverse through the world. After the events of Shibuya, his execution was mandated due to his suspected collaboration with Satoru Gojo, and was classified as a special grade level threat due to his ability to create and control an army of cursed corpses.

## History

Kokichi was born to non sorcerer parents and was born bearing a Heavenly Restriction that gave him a body which was described to be broken and incomplete. He was born without a right arm and both of his legs were incomplete; he had no feeling below his waist; his skin was so sensitive that even the levels of natural light provided by the moonlight would burn him and the pores on his body always felt like they were being stabbed with needles. In exchange for all of these physical limitations, he was granted boundless amounts of cursed energy and a vast increase in range over his cursed energy output and innate technique.

Upon learning that this child was born with a vast amount of cursed energy production, it attracted the attention of the jujutsu community, with him being raised by the Jujutsu High schools in particular. However, most members believed that there was no hope for this child to survive past the age of infancy and decided to abandon him, but due to the influence and opinion of Satoru Gojo, they were forced to raise the child in the best way that they were able to using advanced medical and jujutsu technology.

The condition for the arrangement to raise Kokichi was that the child would become a jujutsu sorcerer in the future, this incredibly difficult condition to fulfil was set despite the physical limitations of Kokichi's body in order to trap Satoru in a lose-lose situation and then punish him for his actions. Luckily for Satoru, he eventually became acquaintanced with the genius engineer " ", who developed and personalized Kokichi's Mechamaru model cursed corpse puppets after finding out about his situation and deciding that he would do whatever he could to help Kokichi, building and repurposing his failed designs so that Kokichi could use them as proxies to live out his live in a "normal" way for a jujutsu sorcerer, as well as to be able to fight against cursed spirits and curse users.

Kokichi's physical conditions were so severe that to this day it is considered a miracle (or a curse) that he survived through the stages of childhood. His parents were also made to believe that their child had died due to the astronomically low number of chances that Kokichi had to survive. When Kokichi was old enough, he eventually enrolled into Tokyo Jujutsu High, rising through the grades of a jujutsu sorcerer using his Albatross Mechamaru, and later, his Ultimate Mechamaru, managing to reach a rank of semi-grade 1 using the former, and a rank of grade 1 using the latter.

Kokichi eventually became very close with "Kidenshi", becoming his apprentice and being very invested in the study of jujutsu applied to engineering and programming, with the creation of more Mechamaru models, weapons that could be equipped onto them and software that could be uploaded to them. Kokichi, "Kidenshi", Satoru and Agoku were the main collaborators behind this weapon development which was kept a secret from the jujutsu higher ups in order for them to be able to avoid execution sentences for their ability to create an army of cursed corpses.

## Jujutsu

In exchange for being born with such a hellish and torturous body, Kokichi was granted a cursed energy production equivalent to that of a special grade jujutsu sorcerer, an external storing mechanism that could contain his vastless cursed energy and an increase in range in his Puppet Manipulation cursed technique, allowing him to control his cursed corpses all across Japan by bypassing the limits of his cursed energy output and range.
After Kokichi was healed by Mahito, his Heavenly Restriction was nullified, which completely stopped his cursed energy production, but left him with the external storage system and all of the cursed energy he had accumulated up to that point; though the range of his Puppet Manipulation was severely shortened, it is still vast enough to encompass an area as large as Shibuya and a sizable portion of Sendai. An important consequence of this healing is that since Kokichi can no longer produce cursed energy, if he runs out of his cursed energy reserves, he will no longer be able to act as a jujutsu sorcerer, as he would not be able to use cursed energy, though he would still be able to see cursed spirits and cursed techniques.
This storage system effectively allows Kokichi to never run out of cursed energy, as he can constantly fill his reserves of cursed energy by accessing this mechanism. Though there is a limit to how much cursed energy Kokichi is able to channel into his body at once, as overloading his body with too much cursed energy at once would cause it to strain and fracture due to the volume of energy. Kokichi is limited by the cursed energy reserves that his own body can hold, as he himself can only hold a small fraction of his total amount of cursed energy, he is also limited by the speed at which he can regain his cursed energy, with it being a more gradual process. Though a big advantage of this system is that Kokichi is able to channel cursed energy into his body while he is using cursed energy, making it possible to recharge cursed energy during a fight as he is using it.
To Kokichi's opponents, the amount of cursed energy he has presents two very strange qualities: the first is that either when Kokichi or his Mechamaru puppets use cursed energy, the amount of their cursed energy they have does not decreased, appearing as if his attacks are costing him 0 cursed energy to use, this is a result of Kokichi recharging his cursed energy as he uses it. The second quality is that when Kokichi or his puppet's cursed energy reserves start to deplete, they start to unexpectedly fill back up again in a gradual or burst amount, this is a result of Kokichi desperately filling up the reserves of his body when they start to deplete. These observations were made by Ryu Ishigori during their fight in the Sendai Colony, where Kokichi started to exhibit physical and mental drawbacks such as coughing up blood, bleeding internally and feeling like his brain was about to overheat or explode due to the amount of cursed energy; this was a result of him constantly filling up his reserves, as well as filling them up in large quantities in order to be able to equal Ryu's immense output of cursed energy. Kokichi can use reverse cursed technique on his brain in order to lower the overheating symptoms of his brain, though because of his limited use of this technique, it is only a temporary solution as this can cause more damage to him in the long run.

The total amount of cursed energy he has completely eclipses that of other special grades such as Yuta Okkotsu, Rika Orimoto and even Ryomen Sukuna. Kenjaku considers him to be one of the biggest threats Jujutsu High has simply because of how much cursed energy he possesses. He has enough cursed energy to pilot every single Mechamaru model cursed corpse he has owned at once, and has enough energy to cast his domain expansion dozens of times in a row, though in reality his body would not be able to handle the physical and mental stress of casting a domain expansion multiple times.
Kokichi had a more rudimentary understanding of cursed energy compared to his peers at the same level of strength as his puppets before he was healed, it was noted that his cursed energy "leaked" more and his use of it was inefficient when compared to other sorcerers, this also applied to his use of his Mechamaru puppets. Kokichi opted to overwhelm his opponents using vast amounts of cursed energy and heat emissions rather than precise cursed energy control. However, after he landed a Black Flash in Shibuya, his understanding of cursed energy, as well as his Heavenly Restriction skyrocketed, this let Kokichi have a much better finesse at using cursed energy than before, and to concentrate his cursed energy blasts in a more effective way than before, his ability to reinforce his body and his puppets with cursed energy also experienced a large improvement, as demonstrated with his fights against () & Ryu Ishigori.
The first time he was able to use this technique was in the Evening Festival of the Shibuya Incident after being healed by Mahito. After the arrival of his ally (Takagari Kidenshi) and Mahito's ally Fubuyama, Kokichi let his guard down, which allowed Mahito to break the cockpit of his Absolute Mechamaru, leaving him exposed to danger. In response, Kokichi threw the last remaining mechanical tube which contained the simple domain technique, he then remotely activated it as Mahito approached him for the finishing blow, disturbing the cursed spirit's cursed technique and leaving them wide open to an attack, Kokichi then imbued his body with the maximum amount of cursed energy he was able to muster and then jump kicked Mahito in the face, performing his first Black Flash and pushing the spirit back long enough for Kokichi and (Kidenshin) to be able to escape.

Kokichi was able to make his Absolute Mechamaru shift its fingers into spikes or shooting mechanical tubes that were both capable of injecting Simple Domain's effect into Kokichi's target. In Mahito's case, being hit with a projectile containing Simple Domain affected his soul because it neutralized his Idle Transfiguration technique upon detonation. Kokichi was also able to use it to protect the cockpit from an enemy domain expansion.
Kokichi was only able to produce five of these tubes by the time of the Shibuya Incident, during his fight with Mahito, he used the first tube alongside tracking system of Absolute Mechamaru in order to accurately hit the cursed spirit, then following up with an Ultimate Cannon blast which destroyed half of the cursed spirit's body since the simple domain disrupted Mahito's Soul Transfiguration, allowing Kokichi to him them without having to use a technique that could also damage the soul. The second tube was intercepted and destroyed by Mahito in midair when it was fired, who recognized the danger that Kokichi's techniques possessed. The third was used to protect both Kokichi and his puppet from Mahito's Self-Embodiment of Perfection, he faked his defeat so that Mahito would let their guard down, after this feint, Kokichi used the fourth tube to activate Simple Domain inside Mahito's body after piercing them with his puppet's spiked fingers, before trying to follow up with a one handed Machine Press, which was intercepted by the arrival of Fubuyama. This allowed Mahito to break the cockpit area of Absolute Mechamaru, nearly killing him were it not for the arrival of "Kidenshi", when Kokichi jumped from the cockpit, he engaged in a brief close quarters encounter with Mahito, and by reinforcing his body with cursed energy, he increased his speed enough to make a quick movement to catch Mahito off guard, who underestimated the shut in by thinking that we would be useless once his puppets were destroyed, this allowed Kokichi to pierce Mahito with another Simple Domain, allowing Kokichi to kick Mahito back using a Black Flash long enough for "Kidenshi" to be able to set up an escape after a distraction.
After Kokichi's body was healed, he is now be able to perform this technique by himself, as well as being able to use even when remotely controlling his Ultimate Mechamaru V2. This was shown when he activated Simple Domain simultaneously on both himself and Ultimate Mechamaru V2 in order to protect themselves from Ryu Ishigori's ( ). He was taught how to use this technique by both Kasumi Miwa and Atsuya Kusakabe during his training after the Shibuya Incident.
Every single part that makes up his domain expansion except for the barrier itself is a cursed corpse, which he can control to attack the opponent all at once. The binding vow of this domain locks the target inside the center of the tub while also providing the sure-hit possessed by most domain expansions, however, Kokichi's domain expansion is not a sure-hit kill technique, as several strikes are often necessary in order to kill an opponent. It is possible to escape this domain without using any barrier techniques by escaping the bathtub, however, the red liquid is noted to be extremely dense and sticky which results in it weighing the target down. This liquid has been noted to be hard to move in and even harder to escape from, the liquid is of questionable origin and the ingestion of it can cause harm to the target's body, it is speculated that this liquid contains blood, as well as several other harmful components. This domain also seems to decrease the physical strength and speed of anyone inside it, including Kokichi's own capabilities.
Kokichi can attack the opponent using a large amount of methods such as firing from the broken Mechamaru: Albatross Models; using the tubes and wires which are filled with medications which are meant to slow down or incapacitate the opponent; using a variety of sizes of needles and syringes that are also filled with harmful substances; breaking any of the wires and causing a short circuit which electrifies anything inside of the bathtub; causing the opponent to trip and fall down in order to drown them; causing the tubes to collapse and fall on the opponent or to have them either wrap around or smack the opponent. However, the finishing move is a direct hit from a charged Ultimate Cannon shot fired from the large cannon from the cursed corpse puppet that resembles his Mechamaru: Absolute Model, but since this is not the version that once existed but rather one created from within his domain expansion, it has a much higher limit to the amount of cursed energy it can handle, enough to handle over one month's worth of his cursed energy at once to fire and decimate his opponent.
