Oboro Mu

**Oboro Mu** (おぼろ 無, *Mu Oboro*): Is a major supporting character in the *Jujutsu Kaisen: The Star, The Blight, and The Rose* series, and one of the main protagonists of its prequel, *Jujutsu Kaisen 0: Jujutsu High Rebirth*. He is currently a special grade second-year at Tokyo Jujutsu High and a Hybrid human-cursed spirit. He is the adopted son of Naobito Zenin, and heir to become the next Clan Head. He is classmates with Maki Zenin, Toge Inumaki, Panda, Yuta Okkotsu, and Death Scythe, while also serving as a role model to the first-year students.

After the death of Naobito Zenin, his adoptive father, Oboro was made the 27th Clan Head of the Zenin Clan ahead of his older brother Naoya.

## Appearance

Oboro is a tall and fit young man, standing taller than most of his classmates. He wears his brown hair down to his neck with his hair parted to reveal the black markings on his forehead. He has cyan blue eyes and typically wears a blank, unexpressive look, which Panda attributes to him trying to “seem cooler than he is”.

As a second-year student, Oboro wears a custom jujutsu high uniform jacket, missing the buttons with plain gray pants and dark colored boots.

As a first year, Oboro and Maki had recently left the Zenin Clan. Oboro’s hair was slightly shorter, and he wore a lip chain along with his multiple ear piercings, and had an eyebrow piercing on his right eye. He wore a custom jacket and pants, with dark red shoes.

## Personality

Prior to his adoption into the Zenin Clan, Oboro was “raised” in a poor household in an even worse environment, leaving him very unexpressive and isolated. After his fathers death and Oboro’s being discovered by Naobito Zenin, Oboro was taken in by the man, becoming his adopted son.

As a member of the Zenin Clan, Oboro was enveloped in its terrible ideals, becoming close to his older brother, Naoya, and being instilled with his brothers ideals and beliefs. It was here that Oboro gained his multiple piercings, becoming a cruel and boastful individual, with these characteristics only growing after the revealing of his cursed technique.

It wasn’t until witnessing Naoya’s violent and physical abuse of Maki that Oboro began to realize the true nature of his new family, and after stopping Naoya, he began to reform from the vile teachings of the Zenin Clan. Although Maki initially hated Oboro, just like the rest of the clan, Oboro befriended her when they were 12, and both began to plot their escape from the Zenin Clan. By the age of 15, the two had become the black sheep of the clan, with even Naoya attempting to bully his younger brother, but to no avail. When Maki and Oboro were leaving the clan grounds, Naoya attempted to stop them with force, only to be bested by his younger brother, who was now determined to leave all of his past behind.

After enrolling in Tokyo Jujutsu High, Oboro is a more cheerful and energetic person, constantly joking with Panda and watering plants with Toge. He became Maki’s de-facto sparring partner prior to Yuta’s enrollment, and developed romantic feelings for her. After meeting Yuta, Oboro became fast friends with the oddity, the two bonding over their unique circumstances, with Yuta claiming Oboro to be his best friend during the pairs battle against Suguru Geto. Oboro had made a habit of calling Rika “my girl”, and jokingly claiming that he would marry her if Yuta didn’t.

As a second-year, Oboro is much more mature and confident. He is greatly respected by Nozomi, Megumi, and Ai Barahata, his underclassmen, and was able to quickly earn the respect of Nobara Kugisaki and Saki Rindo. Oboro acts as the ringleader of the students at Tokyo Jujutsu High, being seen as the de-facto leader by the students due to his confident and cocky nature and consideration to his underclassmen.

According to Maki, now his girlfriend, he has grown up a lot in the previous years, and believes him to be “more of a man than anyone else in the clan”. Oboro has been noted to be rather rude to those he’s trying to train, such as when he was exasperated with Yui Sakamoto’s inexperience during their fight, saying that Yui’s rank as a special grade was a joke and an insult to the title of special grade, stating that he was nothing like himself and Yuta, or even Nozomi.

Oboro has a habit of being a self-proclaimed “technique connoisseur”, judging almost every cursed technique he comes across, and rating it’s value based on how well he could use it, if he decided to copy it. This was shown when he confronted Uraume for the first time, and upon witnessing his Ice Formation Technique up close, called it an “extravagant technique”, with his cursed mouth licking its lips as he claimed he wanted to “devour it.”

## Powers and Abilities

**Overall Skills**: Oboro is one of only a few special grade sorcerers recognized by Jujutsu High and possesses one of the highest potentials of any student at Jujutsu High. Satoru Gojo, the strongest sorcerer of the modern era, believes that Oboro has already surpassed prodigies like Yuta and Hakari, and thinks that he could reach his own level soon. He has been recognized by Jujutsu society as a powerful sorcerer befitting and even exceeding the title of special grade, with even the likes of Kenjaku and Sukuna recognizing him as a threat enough to take very seriously, with the latter comparing Oboro to Shichihyaku Fujiwara, one of “the strongest” sorcerers in history and the only other person to have ever nearly killed him.

As a self proclaimed “cursed technique connoisseur”, Oboro is extremely well versed in the functions of cursed techniques and cursed energy applications, being able to deduce techniques from seeing them used once. He is very picky about the cursed techniques he copied, an example being when he chose to copy Toge’s Cursed Speech due to its applications, but did not copy Death’s Cursed Tool Empowerment technique due to the uncertainty of its effectiveness in combat. He also feels “attached” to certain cursed techniques that he has copied, such as when he refused to give up his Survey technique in exchange for Mei Mei’s Black Bird Manipulation.

Prior to enrolling in Tokyo Jujutsu High, Oboro received elite training from the Zenin Clan, becoming a member of their most elite group, The Hei, at the age of 12. During his and Maki’s own flight from the clan, Oboro bested Naoya Zenin, a powerful sorcerer and leader of The Hei, with his own cursed technique, nearly fatally wounding his older brother.

As a first-year, Oboro was labeled a special grade sorcerer upon his enrollment, being the only one until the enrollment of Yuta Okkotsu. During a mission to exorcise a grade 1 cursed spirit with Yuta, Oboro easily exorcised it within seconds, much to Yuta’s amazement.

During 2017, Yuta and Oboro were sent to Kyoto to even out the numbers for the Goodwill Exchange event. Both Oboro and Yuta decimated the event and all the students, including Aoi Todo. This led to the pair being called “The Demon Twins” by jujutsu society.

During the duo’s battle against Suguru Geto, the curse user continually attempted to separate the two, believing Oboro to be the far more dangerous opponent of the two. Due to Oboro’s still lack of understanding of his technique, he was hit with a semi-Maximum:Uzumaki upon mimicking Geto’s Cursed Spirit Manipulation, knocking him out of the fight temporarily.

As a second-year student, Oboro gained near perfect control of his technique, and was seen as the strongest student Tokyo Jujutsu High had, being greatly respected by his underclassmen. During the Goodwill Exchange Event, no one on the Kyoto Jujutsu High team, save for Todo, wanted to be anywhere near Oboro, claiming him to be a “complete monster”, with Noritoshi Kamo attesting to this, recalling Oboro and Yutas overwhelming victory during the last Exchange Event, as well as “stealing” the Kamo Clans prized technique. During his fight against Yui Sakamoto, Oboro easily outclassed the inexperienced fighter, which the formers technique being near useless against Oboro’s superior speed and fighting capabilities, with Oboro “allowing” Yui to activate and preform his technique to the fullest purely because he wanted to see if “It was worth stealing”, before ultimately deciding Yui’s technique was too complicated to be effective in one-on-one confrontations. Before Oboro could begin to fight the special grade curse Hanami, a large amount of grade 1 cursed blocked his path, and he was stalled by Makaze before both special grade curses retreated, with Oboro nearly destroying Makaze with a close range Maximum: Uzumaki.

During the Shibuya Incident, Oboro was able to pressure Kenjaku after Satoru Gojo’s sealing, with the ancient sorcerer being forced to use 6 special grade, 80 grade 1, 259 grade 2, and over 400 grade 3 and 4 cursed spirits to simply block and evade Oboro’s onslaught, causing Kenjaku to need to use his reverse cursed technique to heal his broken body on multiple occasions during their battle. Oboro was later locked in combat with Meirei, an extremely dangerous and powerful curse user, with both fighters being forced to withdraw after Kenjaku’s finding of Mahito. Oboro was also one of the last sorcerers standing in the final attempt to stop Kenjaku, Doku, Uraume, and Meirei.

During the Shinjuku Showdown, Oboro was labeled one of the Heavy Hitters of the jujutsu sorcerers, being considered extremely crucial to the plans to defeat Sukuna. During his bout against The King of Curses, Sukuna himself believed that Oboro was reaching toward surpassing Satoru Gojo, and fully believed that Oboro could kill him, especially after Oboro’s activation of Petty Decree, which was a technique compared in power to Satoru’s Limitless and Six Eyes technique by “the strongest” sorcerer himself. Sukuna acknowledged both Oboro and Yuki Tsukumo during their battle to defend Hiromi Higuruma, putting their jujutsu abilities on par with his own, calling the two of them by their full names. Sukuna was further impressed by Oboro after his simultaneous activation of Mythical Beast Amber alongside Petty Decree, with the King of Curses seeing vestiges of Shichihyaku Fujiwara in the young sorcerer, stating that this fight against Oboro would be only the 2nd time he’s had to genuinely fight for his life.

During his battle against Sukuna utilizing Mythical Beast Amber, Oboro learned to see the “start” of cursed energy, something even Satoru couldn’t understand. Oboro was capable of far surpassing even the initial user, Hajime Kashimo, in utilizing his technique, with Sukuna crediting Oboro’s rapid growth in their battle superior to Satoru’s or even his own.

### **Physical Prowess**

**Unique Physical Makeup**: As a human-cursed spirit hybrid, Oboro was born from a human father with a unique body composition, and a cursed spirit. As an anomaly, Oboro is physically stronger than most, comparable to the likes of superhuman strength of Yuji and Maki. Along with this, Oboro was born with two brains, which allow him to utilize his technique.

**Expert Hand-to-Hand Combatant**: Oboro is an exceptional close quarters fighter, having had elite training from The Hei, the strongest of the Zenin Clan. He can easily keep up with incredible fighters like Maki, Yuji, and Nozomi. Due to his multitude of techniques, Oboro is a very unpredictable fighter.

### Jujutsu

The techniques true strength, however, comes from its ability to use multiple techniques at the same time, allowing the user to mix several techniques at a time into even more powerful moves.
