Agoku Ketsuki

" *I'm just a man who's trying to live a fun and enjoyable life, it's just that my definition of fun doesn't tend to match well with others.*"

— Agoku Ketsuki when describing himself.

**Agoku Ketsuki** (血木顎食 Ketsuki Agokū) is a major supporting character in the Jujutsu Kaisen: Resurrection series. He is a former member of the Ketsuki Family, the illegitimate son of the current head Tetsuzo Ketsuki, and the older brother of Mikoto Ketsuki, the former soon to be heir. Agoku left the Ketsuki family due to the abuse and neglect he suffered while living there. After leaving the Ketsuki family, he became a curse user who was infamous for his assassination abilities despite his young age, though this path of darkness ended up spiraling him into self destructive and suicidal tendencies, with him eventually becoming a diacetylmorphine addict.

He was eventually scouted by Satoru Gojo, who recognized his potential as a jujutsu sorcerer, as well as to change his ways, rehabilitate himself, and to use his skills in favour of Jujutsu High. Agoku accepted because he believed that if the strongest sorcerer alive also wanted to change the way things worked in the jujutsu society (such as the abusive treatments of the sorcerer families, the cowardly, old-fashioned nature and general incompetence of the jujutsu higher ups), then maybe there really was a chance to make it a better place, joining him as a major part of his secret plan to overthrow the higher ups and sorcerer families.

Agoku eventually became a grade 0 jujutsu sorcerer, recognized as one of the most dangerous and crazy sorcerers, feared by both curse users and the jujutsu higher ups alike. He serves as an instructor for Tokyo Jujutsu High, being an invaluable resource for both his students and fellow colleagues. He is also an associate of the Gachinko Fight Club, which he fights in, as well as directs, alongside Kinji Hakari and Raiko Todoroki. He is currently on a death sentence and is wanted for execution due to his suspected compliance with Satoru during the Shibuya Incident, as well as his confirmed slaughter of the Ketsuki Family after the events of Shibuya.

## Appearance

Agoku is a tall, well built man with black hair that reaches up to around his nape, which he usually keeps tied up; however, after the Shibuya Incident, Agoku cut his hair due to no longer being able to take proper maintenance of it, though he does keep a very similar hairstyle. Agoku usually presents himself with black eyes, though he later reveals that they are actually pupils that he wears, with his natural eye color being red. He wears pupils to seem less intimidating to the students and his colleagues.

He tends to only wear black and red colored clothing which he finds comfortable, he also likes wearing white but says that it gets stained too easily. He often ties his hair up whenever he is not during combat to preserve its shape and to make sure it does not interfere with his activities. His physique is similar to that of Toji Fushiguro, having been compared to be that way by both Satoru and the representation of the manga panels where his presence overlaps with that of Toji, though Agoku has a smaller frame than Toji, he is still very muscular, having some of the most well defined chests, abdomens and backs in the series.

Agoku has a multitude of scars scattered across his body, mostly focusing on his chest and back, two areas that are harder for the ordinary person to find out about. He has several slashes and stabbings caused by blades and spikes all across his chest and back, all of them were caused by the abusive training and torture he was submitted to by his father, Tetsuzo Ketsuki. The most notable scars on his body include a large X shape across his chest made with a branding iron to mark him as the reject of the Ketsuki family, and a large cut across his stomach reminiscent of the practice of harakiri, which Agoku was forced to make himself in order to leave the Ketsuki family.

During the Shibuya Incident Arc, he lost his left eye after being pierced by Kuroshiei's shadows, and later lost his left arm, being sliced off during his battle with Kenjaku. He now wears a prosthetic for his left arm and an artificial left eye so that it is harder to tell that he can only see with one eye.

His prosthetic arm was destroyed during his battle with Soji Okita in the Tokyo No.1 Colony, and he chose not to replace it until after Hromi Higuruma joined him. He replaced it with a spare prosthetic that was visibly simpler, with Agoku saying that he only had two prosthetic arms made for him. Though Agoku severed this prosthetic before his fight with Ryomen Sukuna, considering it too weak to be able to go up against the King of Curses, instead opting to use his Hellhound Jaws to create a prosthetic arm and fighting Sukuna using it.

During the Shinjuku Preparation Arc, his arm and eye were healed by Yuta Okkotsu, with Agoku being extremely grateful to him. During his battle in the filler Jujutsu Sorcerer Tournament, his right arm was blown off by Hajime Kashimo's electrified cursed energy lightning discharge, but was subsequently healed by Yuta after the fight concluded.

During the Shinjuku Showdown Arc, both of his hands were sliced off by Kenjaku's Cursed Spirit Manipulation, however, Agoku showed that he was able to use a Reversed Cursed Technique, with him immediately turning the tables on him by healing both his hands (but being unable to heal any of his previous scars) and then subsequently healing the injuries Kenjaku would later inflict on him, which even included having his stomach pierced by Kenkaju's Maximum: Uzumaki.

## Personality

He is a rather eccentric and unusual man. He also has rather strange mannerisms. He is considered my many to be insane due to his personality during combat and him not being afraid of retribution from the higher ups, even challenging them to kill him if they could. He is not afraid to voice his own opinions and does not like spending time around people he does not like such as the jujutsu higher ups.

Despite these traits of his, he is described as a relaxed and easy going person whenever he is not doing any activities, he does not mind talking with people as long as he enjoys the conversation. He particularly enjoys his conversations with Satoru Gojo and especially Nanami.

He is resentful towards the sorcerer families due to the way he was treated by them and stated that if Satoru Gojo were to destroy them, he would gladly join him, even asking him if he could fight against the Kamo family without the Limitless user interfering.

He can sometimes come off as quite selfish as he states that he lives for the joys and rushes of life and doesn't care about much else. Despite this statement of his, it is shown that he at least subconsciously cares for others, as he cares for the wellbeing of his friends and even protected the students from attacks, claiming that his body moved before he could think properly, later saying that he though it would be a shame for them to die and that others would be saddened by their deaths.

He tends to enforce his beliefs of enjoying life to others, particularly those that do not have much free time such as Kento Nanami or Shoki Ieri. He also hangs out with the students as he believes that although sorcery is stressful, they should have the right to enjoy themselves and have time to do so. He does not force anyone to hang out with him, as he respects boundaries and merely entices people to do so, although he sometimes, in his own words, does not "play fair" as he sometimes uses incentives or trickery.

Despite his attitude, he is quite responsible and does not take minors to places where they are not allowed, showed when he objected to taking Yuji to a gentlemen's club and asked Kokichi to only read a specific part of the book he wrote for him and to read the rest when he became older.

He is constantly on the search for different types of activities that mainly involve the raising of a person's body temperature and blood pressure or high adrenaline activities. He also is constantly looking for cursed spirits and curse users to fight, he refuses to take on any missions lower than an estimated semi-grade 1, as he does not care to fight weaker opponents as they do not challenge him enough to make him feel joyed.

He usually has either a relaxed face or a smile which others describe as disturbing on his face which he himself claims to be a sign of enjoyment. When he is angry or in the presence of the higher ups the smile turns even more diabolical. with his eyes seemingly saying that he will kill them if they were to try anything.

He is quite sadistic, as he enjoys hurting and fighting against cursed spirits and curse users, although this does not extend to non combatants, nor to weaker cursed spirits and curse users, which he simply exorcises without giving them much attention. He is also shown to be a masochist as he was smiling during his fight against Dagon despite his injuries from the cursed spirit's shikigami, claiming that pain is also one of the joys of life and that there is no better feeling than the thrill of death.

It seems that he does not have the same feelings when he is angered, nor when a sufficiently despairing situation is happening, as while he was smiling during his fight with Kuroshiei, he did not do so when fighting Psuedo-Geto, recognizing the curse user as a threat that needed to be eliminated for the greater good, as well as directing his anger towards the curse user when he found out about the sealing of his friend Satoru.

## History

Agoku was born to the Ketsuki family, a branch of the Kamo family. His father, () Ketsuki married Vietnamese woman and had a child with her, who perished after giving birth to him. Since both families value bloodlines and techniques more than anything, when Agoku developed an innate technique instead of an inherited technique he was ostracized. This grew even more severe when his innate technique was considered rather vulgar and unsuited to one of the sorcerer families despite its possible potential.

He was harshly treated as a child, his father believing his only potential would ever be to use cursed tools in combat, which is why he made him undergo a brutal training. He was physically abused by his father for this and constantly cried out, although this did not change anything. One day he suddenly stopped crying entirely, as he was no longer able to, he later described this in the future as "having all the emotion in him sucked out".

When he was a teenager, Agoku ran away from the Ketsuki family and stated that he would continue on his own and make them regret doing that to him. Agoku went through a brutal training and taught himself numerous ways of combat and assasination, as well as honing and developing his techniques, obtaining a supply of powerful cursed tools, a cursed spirit that could hold these items for him, as well as establishing relationships with prominent figures such as Toji Fushiguro so that he could overthrow the families,

He became a curse user for a few years before he even reached the age of 18 taking multiple jobs which usually had to do with assasinations, however, he later saw hope in the likes of Satoru Gojo, as he believed that if the strongest sorcerer also wanted to change things then it would be possible if more people were to join them. Satoru used his influence to introduce Agoku back to the world of jujutsu but he would forever be ostracized for his past deeds.

At some point in time after he became a jujutsu sorcerer, a member of the Kamo family became a curse user who was sought after due to having committed numerous crimes Agoku found and confronted the former member, brutally murdering them with his newly honed skills so the families would regret their actions and discovered that the person they once disowned had become more powerful than them.

Agoku later seemed to have clamed down, taking a more relaxed personality, even choosing to take care of a group of snakes, improving his knowledge in ways other than combat or infiltration and training and looking after the Jujutsu High students, who which he wants to eventually overthrow the higher ups once they have enough members and powers, having recognized that not all sorcerers are evil but that they can become that way if they are treated as such.

## Abilities

**Overall Abilities:** As a semi-special grade sorcerer, Agoku is a very powerful sorcerer, despite the fact that Agoku tends to hold back to make his fights more enjoyable, when he actually tries to win he becomes an incredibly difficult opponent to face. He is a powerful adversary and is feared by the jujutsu higher ups due to his erratic behavior. Satoru Gojo states that is a rather dangerous man even though he cannot actually harm him, the sorcerer also acknowledges the fact that he can take a hit and keep going.

He was able to fight on rather equal ground on his own against Dagon, a semi-special grade cursed spirit while still holding back, and begin to overwhelm the cursed spirit once he started to get serious, he was able to counter Dagon's domain expansion and brutalize the cursed spirit to the point where Ultimate Mechamaru's Ultimate Cannon left it in a near death state. He later stated that he regrets not fighting to his fullest and that he could have exorcised Dagon by himself.

During Shibuya, he was able to effortlessly defeat Niji Ebina, a curse user considered to be around the level of a semi-grade 1 sorcerer, then hold his own against Choso, a semi-special grade cursed spirit alongside Yuji Itadori. Although he was initially overwhelmed by the cursed spirit's physical prowess, he maintained his distance and then proceeded to continuously injure Choso using his weapons and innate technique to the point where the cursed spirit was having a very hard time defending themself against the teamwork of Agoku and Yuji. Agoku claims that he could also defeat Choso on his own but he was stopped by Jogo, who he considers to be a horrible matchup for him.

He was later able to fight and severely injure Kuroshiei, another semi-special grade cursed spirit, with the help of " ", although Agoku claimed that if he did not have the support of the alchemist, and was not lent the Jet-Black Shadow Sword by Megumi Fushiguro then he would have probably lost the fight. This cursed spirit was considered to be above the level of the previous two semi-special grade cursed spirits that he had fought previously, being able to use shadows to move and attack faster than the speed of sound.

Pseudo-Geto later considered him to be an unexpected threat to his plans due to the power of his innate and inherited techniques and his arsenal of weapons. During their brief confrontation, Agoku had his right hand severed by the curse user as a result of being worn out from previous fights, although he claims that even at full strength he would not be able to defeat the curse user.

He was later shown to be able to keep up with Yuji Itadori's physical prowess with only his cursed energy reinforcement, Yuji himself noted that he had a very hard time keeping up with Agoku's erratic movements and that he could not have defeated him if he had used his innate technique. He was also shown to be able to overwhelm Hiromi Higuruma with relative ease, a culling games player stated to be at the level of a grade 1 sorcerer.

**Master Weapon Specialist:** Agoku has shown to be very proficient in using multiple different weapons, including a sword, a whip-sword, a two sided lance and a chain, his expertise is said to extend even beyond these weapons. His proficiency with weapons is stated to be on par or similar to the likes of Toji Fushiguro's capabilities. He uses weapons as his main form of combat and can fight on par with semi-special grade cursed spirits when using them.

**Master Hand-to-Hand Combatant**: Agoku has shown to be very proficient in his ability to fight bare handed, having received intense training and later training by himself, he has also shown a high degree of improvisation and unorthodox methods on top of his own knowledge. He does not usually fight this way as he prefers using weapons, although some exceptions exist such as when fighting other humans who are not using cursed techniques such as Yuji Itadori and Chaimail.

He is considered almost as skilled as Megumi Fushiguro and on par or above the likes of with Yuji Itadori and Choso, although the latter two's styles of combat differ greatly from his. He is able to fight opponents much larger than him as seen during his fights in Raiko Todoroki's club and can even overwhelm other highly skilled combatants such as Maki Zenin and Satoshi Kagemoto. He is able to match and predict Yuji's movement patterns, as well as use his Knee Release and Manji Kick against him despite only seeing him use it once against him.

**Keen Intellect:** Agoku has demonstrated the ability to quickly figure out how his opponent's cursed techniques work and devise strategies for countering them. Notable examples of this being able to find out how Dagon's domain expansion worked and figure out a way to fight back alongside Kokichi and being able to figure out how Kuroshiei's cursed technique worked and use the cursed spirit's own technique againts it by using the Jet-Black Sword. He is also capable of overwhelming an opponent after finding out how their patterns are when fighting, he is able to replicate certain techniques after watching them only once, such as Choso's Supernova and Yuji's Manji Kick.

**Inhuman Pain Tolerance:** Most likely thanks to his masochism and general insanity, Agoku is able to handle large amounts of severe injuries without deterring, even laughing at the feeling of them. Although when he is angered, he does not do so and turns his pain and anger into power by channeling his negative emotions into cursed energy which strengthens his innate technique even more.

**Poison Resistance**: Agoku has demonstrated a very high resistance to poison, as he stated that several people have tried to kill him using it, to almost no effect. He is even able to drink some types of poison and venom, he says that it tastes good and compares them to the feeling of drinking shots of alcohol, he also states that they can really mess you up if you don't measure the dosis well. However, extremely strong poisons such as the one found in Choso's blood do have an effect on him which causes his skin to rot and to impair his movement.

## Jujutsu

### Cursed Energy Manipulation

I**mmense Cursed Energy**: Agoku possesses an incredible amount of cursed energy, enough to cause the average sorcerer to tremble in fear whenever he releases his energy. He has shown to have enough cursed energy to fight a semi-special grade cursed spirit for a short amount of time and then fight a special grade curse user for an extended period of time, utilizing almost all of his techniques and even combining both his innate and inherited technique, something which requires a massive amount of effort. He then cast both a domain expansion and a maximum technique in succession and continued to fight despite having already exhausted himself, having multiple life threatening injuries and having used up most of his cursed energy.

Black Flash (黒閃 Kokusen): A technique that creates spatial distortion when a user connects with an impact of cursed energy within 0.000001 seconds of a physical hit. The phenomenon causes cursed power to flash black, creating a more potent attack to the power of 2.5 of a normal hit. Agoku claimed that the first time he used this technique was during the Night Parade of a Hundred Demons to exorcise a grade 1 cursed spirit. He was later shown using it against Dagon during the Kyoto Goodwill Event Arc, he was able to severely damage the cursed spirit as well as it serving him the motivation to get psyched up for the rest of the fight.

He then used it during the Shibuya Incident Arc. He first used it during his fight against Choso in order to get into the zone when he thought that the Cursed Womb: Death Painting was actually a member of the Kamo family that had defected due to Choso's cursed technique. He later used it against Pseudo-Geto during which he managed to land four Black Flashes in a row while trading blows, however, the last blow made from his right hand was completely blocked and thus his hand has severed by Pseudo-Geto's counterattack. He has currently performed it seven times.

Agoku claims that he can only perform this attack when he is presented with either a very strong opponent which gives him the excitement to fight and the wanting to be able to fight at his best such as Dagon and Choso or when a desperate situation arises in which extreme odds are against him such as against Pseudo-Geto.

### Binding Vows

**Revealing One's Hand:** A binding vow that is commonly used amongst users of jujutsu. By divulging how his cursed technique works, Agoku can increase the power of his techniques. He only uses it to divulge that his technique is poisonous and that it will rot away the target's body, he usually does this after he lands a hit in order to make the poison spread faster, as well as to create a sensation of fear in the opponent that might cause them to slip up or to start rushing their attacks in order to defeat him.

### Innate Technique

**Hellhound Jaws:** Agoku's innate technique allows him to create and manipulate hellhound-like creatures made out of pure compressed cursed energy that turns black, he can also make it so that only the head and jaws of a creature are manifested. This ability is even shown to have corrosive and poisonous properties as shown when it made contact with Dagon and started to rot and decompose the cursed spirit's body. Agoku stated that this corrosion only works on organic matter, although that doesn't pose a problem to him as he can destroy non-organic matter anyways with the techniques raw strength. While this cursed technique appears to be sentient, Agoku claims that he is only mimicking the behavior of living creatures when using it in order to strike fear into his opponents. Agoku only uses his technique when he is fighting seriously as he has been made to believe that this technique was only made to destroy and the fact that it has extremely high destructive power and could cause collateral damage and be dangerous if crossfire were to ever happen.

### Barrier Techniques

Simple Domain: An anti-domain technique that erects a small barrier around the user to protect them from the effects of a domain expansion. Agoku first used this technique during the Kyoto Goodwill Event Arc to protect both himself and Kokichi Fukami's Ultimate Mechamaru puppet from Dagon's Horizon of the Captivating Skandha, which allowed them to gain the upper hand in the fight after blasting Dagon with long range attacks. He then used it in the Shibuya Incident Arc to protect himself and Kyosei Yamikage from Kuroshiei's Abyss of the Desolate Wasteland, while this was effective in negating the sure-hit technique, both him, Kyosei and Shorenkin Yakushiki were overwhelmed by the amount of shadows created, they were nearly killed but managed to escape once Kyosei and Shorenkin broke the barrier from the outside. He later used it in the Tokyo Colony No.1 Arc to counter the effects of Hiromi Higuruma's Deadly Sentencing during the first retrial, which completely nullified the court based domain's condition of no violence and forced Hiromi to fight him in hand-to-hand combat, allowing Agoku to gain a major advantage during the fight.

## Relationships

### Professional Sorcerers

Kento Nanami: Agoku considers Kento to be his best friend, they are very close and on good terms with each other. Agoku likes spending time with him but gives him space as he knows that he finds it annoying if he is with him for long periods of time. They often go out drinking whenever Kento is off work, they sometimes also invite Satoru and Ieiri to go drinking with them. Agoku has also invited Kento to go to steam baths and activities he claims regular people would find relaxing instead of his usual adrenaline filled activities as he knows that Kento does not enjoy them. Agoku has also shown a certain attraction towards him, claiming that he finds him to be a very attractive man who which he would like to "enjoy time in the dark after hours" although he has never acted upon this.

Despite Kento usually being the one giving advice to others, Agoku recognized his personality and even gave him advice on how to improve his ability as a sorcerer. When Kento later remembered this advice during a near death moment in the Shibuya Incident Arc, he was even able to cast a domain expansion, something which he had not done before, which allowed the sorcerer to escape from Dagon's domain expansion. Agoku is also one of the only characters that refers to Kento by his given name.

**Akira Hishugo**: Despite not being shown interacting with each other, it is stated that they are friends. They apparently occasionally go out drinking and bathing, as well as sometimes sparring, with Akira sometimes being weirded out but interested by Agoku's masochism.

### Tokyo Metropolitan Curse Technical College

Satoru Gojo: They are friends and are on good terms with each other. Agoku likes Satoru because he is a strong person that is against the higher ups, he also finds him to be an interesting person. He is also one of the only characters that doesn't seem to be annoyed by Satoru's personality, even finding it to be quite enjoyable spending time around him and conversing with him. Satoru seems to reciprocate these same feelings, also considering Agoku to be an interesting, albeit crazy person. They sometimes go out and they seem to joke around with the idea of working together should they ever choose to rebel against the higher ups by killing them.

**Raiko Todoroki:** They seem to be on good terms, having both mutual respect and trust for each other. Raiko states that he is one of the top fighters at his fight club and is very profitable due to him being very resilient and able to put on a show due to not being affected as much when bleeding out. Agoku appreciated having someone that understood what he enjoyed (fighting) and told him to tell him if he ever needed something. Agoku is an assistant in his club as well as a regular fighter in it.

They once fought the first times Agoku fought in the club, causing a disturbance due to him being way stronger than expected and messing up bets, this caused a conflict between them that was eventually solved by a fight in which they gained each other's respect at the end. They also seem to have a great degree of trust, as Agoku was his mole inside the Jujutsu community, mostly focusing on Tokyo Jujutsu High, and was also the test that Yuji was given in order to prove himself, which acknowledges that Raiko recognizes his strength .

Shoko Ieiri: They seem to be on somewhat neutral terms with each other. Since Agoku tends to treat his own wounds unless they are too serious, they do not see each other often. Shoko appreciates him giving her very little work but is concerned for him nonetheless. They sometimes go out drinking. Agoku dislikes the fact that she is such a gloomy workaholic and tells her that if she does something that much then she should at least enjoy parts of it. Agoku has stated that he finds Shoko attractive

Megumi Fushiguro: They seem to be on relatively neutral terms with each other, while Agoku is interested in Megumi due to both his technique and personality, Megumi does not reciprocate and openly states that he does not respect him. While they maintain a level of professionality and seem to trust have in each other due to their abilities, they do not spend much time together. Although Megumi does have a lot of trust in him as shown when he lend him his Jet-Black Shadow Sword before the battles in Shibuya started.

Kokichi Fukami: Their relationship is somewhat conflicting. Agoku is very interested in Kokichi due to his condition but realizes that he can do nothing to help him besides hold a conversation and do certain activities with him. Agoku is very saddened by the fact that he is not able to enjoy the regular activities, stating that everyone should have the right to do so, he promised that if he ever got his body back, he would show him how fun the world could be when you have all of your senses. For the most part both of them tend to avoid each other, but they do not mind being together. Agoku seems to specially care for him as he even wrote a book for him explaining the several pleasures in life such as food, activities and how to make sure he would enjoy his relationship, much to Kokichi's embarrassment when having to read the last part.

Maki Zenin: Agoku appears to be fond of Maki due to her history and her desire to spite her sorcerer family. Agoku wishes her well in her objective and sometimes spars and assists her during straining so she can become stronger and eventually surpass the other members of the Zenin family. Agoku has also said that Maki is somewhat like his ideal type of woman, although he is not attracted to her due to their difference in age.

Yuta Okkotsu: Agoku is very interested in Yuta due to his history, as he would like to know more about what happened with Rika, as well as Suguro Geto but feels like he should not mention it. Yuta does not have a defined opinion of him, considering to be crazy albeit reliable for his performances during his time as a sorcerer, especially during Shibuya.

Yuji Itadori: Agoku does not seem to mind Yuji being Sukuna's vessel, considering it something that makes Yuji more interesting than the average sorcerer. Agoku has shown to be somewhat of a mentor to Yuji, occasionally giving him advice and hanging out with him. They sometimes watch movies together, although Agoku does not take him to any extreme places due to his age, telling him that he will do so when he gets older.

**Kasumi Mizuwa**: Agoku does not seem to have much of an opinion on her, seeing her as an average non-interesting sorcerer. He slowly seemed to attract his attention, like when he believed that it was weird that such a kind person was a sorcerer and that she was either crazy or hiding something. His opinion of her seems to have improved after learning more about her and seeing her relationship with Kokichi, as he calls them the "lovebirds'' Agoku even passed down his snake sword onto her after seeing her manifest her innate technique, despite these factors they do not seem to be close with each other.

### Kyoto Metropolitan Curse Technical College

**Satoshi Kamo**: Agoku has conflicting feelings towards Satoshi as he is the current heir of the Kamo family, which he despises the most out of all of the families due to being a former part of it himself. He even fought him with the intent to kill him if he found him displeasing. After Agoku dominated him in combat and showed his true beliefs, the mad sorcerer gave him a chance to prove himself, and told him that he didn't have to follow the standards as he would later have the power to change them once he became the head of the family, even offering to help him in case he ever needed someone eliminated to not give away the fact that he was going to chance the traditions, something which would essentially make him be considered as a curse user.

Utahime Iori: They seem to be on good terms with each other, they sometimes go out drinking. While Utahime enjoys watching sports she does not do so with Agoku as he prefers to actually play them. They also have differing opinions on Satoru Gojo as only one of them actually respects him and is not annoyed by him. Agoku also helps her whenever she has problems with school or sorcerer related aspects.

Yoshinobu Gakuganji: Agoku has a deep hatred for almost every member of the higher ups, especially Yoshinobu as he is the director of a school in which he imposes their conservative ideals. Agoku repeatedly taunts and challenges him to see if he can try and kill him whenever he feels like he steps out of line but does not go out of his way to do so.

### Curse Users

Toji Fushiguro: They met a long time ago and seemed to get along relatively well, they both knew that they would kill each other should they ever be tasked to do so but otherwise seemed to not aggravate each other. They also seemed to go along with the idea of rebelling against the jujutsu community, although they never followed up on this and treated it as a joke since they could not trust each other. They drank when they coincidently met each other and seemed to be able to hold conversations with each other. This changed however, when Agoku found out what he did to Satoru and his treatment towards Megumi, lamenting the fact that he rather liked him before this.

### Cursed Spirits

Dagon: Agoku oddly stated that he wanted to see if Dagon tasted good, much to the cursed spirits dismay and Kokichi's confusion. Agoku seemed to like that way that Dagon looked and acted, but recognized that he had to exorcise the cursed spirit in order to prevent further damages to the students and faculty. Dagon seemed to hate Agoku as it does with most humans and very seriously tried to kill him from the beginning of their fight. Despite the cursed spirit shikigami leaving scars in the sorcerer's mouth, he does not seem to hold a grudge nor be bothered by it.

Choso: At the beginning of their fight they seemed to be on neutral terms with each other, only seeing each other as mutual enemies, however, after Yuji's interruption and Choso seizing to fight, their conversations allowed them to become closer with each other. They seemed to get along well despite having fought as they were both treated harshly by the Kamo family. After having a brief chat they seemed to become close with each other. They both agreed on the idea of meeting later after the battle and seemed to end up on good terms with each other, later fighting alongside each other.

**Kuroshiei**: Agoku thought that Kuroshiei would make a nice pet/companion and was very interested in it but since the cursed spirit refused the idea he said that he would have to put it down. Agoku was happy to fight such a creature but was saddened by having to kill it as he really did want to keep it as a pet. He was very impressed by its abilities, something which was a mutual sentiment between the two. However, thnaks to the interfearence of (), Kuroshiei was able to continue living as one of the cursed spirits being manipulated by his abilities. Agoku gladly greeted the cursed spirit, although to his dismay Kuroshiei did not react very well as well as not trusting him thanks to their fight. He was eventually able to gain Kuroshie's trust and he finds it to be the wolf pet he was never able to have.

* Agoku's surname contains the Kan-on reading for "blood" (血 ketsu), and the Kun'yomi reading for "tree" (木 ki); his given name contains the Kun'yomi readings for "jaw" (顎 ago), and "to eat" (食 ku).
	+ His mother's surname is the Vietnamese word for "ruan" (nguyễn), her middle name means "flower" (hoa) and her given name means "butterfly" (bướm). His younger brother's given name contains the Kun'yomi reading for "to honor, to respect" (尊 mikoto). His father's given name contains the Kan-on reading for "iron, steel" (鉄 tetsu) and the Go-on reading for "construct, build" (造 zō).

* Agoku loves animals, and finds most animals to be more likable than the average person, notable aspects of this include the following:
	+ He is a legally certified snake milker and has an entire complex that is dedicated to the care of those snakes, with specialized enclosures being built for them, and being treated by ophiologists that Agoku employs and treats well, they consider him to be a boss that is not very present due to being busy, but being very effective with the small time he is there. His facilities specialize in the extraction of venom which is sold to medical research facilities in order to create anti-venom. After the events of the Shibuya Incident, the snakes and his employees were transported to Thailand, where they continue to operate, though at a lower level due to not having the same facilities.
	+ He has his own brand of snake wine, which uses the different venom of the snakes in his enclosure to sell as alcohol, they are a highly coveted brand due to their exquisite products and the authenticity of the venom they use to infuse the alcohol. Many his colleagues have tried the venom (such as Satoru Gojo, Kento Nanami, Utami Iori, Shoko Ieiri and Akira Hishugo), they all note it to be a very well tasting beverage, though it has a small hint of weirdness to it due to the venom. Agoku himself likes drinking the unprocessed venom, which he is able to do due to his resistance to poison.
* He is pansexual, as has been shown to have multiple sexual affairs in the bonus chapters with both men and women. Agoku has developed romantic feelings towards Kento Nanami, though he brushes this off as playful flirting. While before the events of Shibuya, he would sleep around with many individuals, he states that if he were to be with Kento, he would never cheat on him and would be together with him until the day they died.
* His favorite superhero is Deadpool, as he finds him humorous and relatable, as well as a surprisingly interesting and complex character.
* He regularly engages with recreational drugs, the one exception being heroine, as that was the drug that he was formerly addicted to. It is notably the only drug that is uncomfortable in being present with, and that seeing the state of other addicts is one of the only things he finds nauseating.
* He used to be left-handed but learned to use his right hand and became a cross-dominant because of the harsh training his father made him undergo. He favors his left hand during daily activities and his right hand during combat. Although he is capable of switching his dominant hand during combat, which can confuse opponents due to the shift in his movement patterns, though he is equally proficient using both sides of his body.
* The author has stated that if Mahito was a human jujutsu sorcerer, he would have gotten along very well with Agoku, to the same extent as the relationships he has with Yuji Itadori and Hajime k:ashimo.

## Quotes

(After landing a Black Flash against Dagon) "*Ah, this feels so good. When it comes to sorcery, there's nothing better than the feeling of performing a Black Flash, this is such a rush, my entire body feels like it's rushing with electricity*."

(While fighting Dagon) "*HAHAHAHA, this is the best, it's been a while since I've been injured like this but I'm having so much fun. Unfortunately, I don't think I'm allowed to enjoy myself much longer, playtime is over, now we fight seriously*.

(To Kokichi Fukami) "*It must feel unimaginably horrible, not being able to eat what you want to eat, to not truly be present when you're having fun with your friends, not being able to feel when you hold and kiss the woman you love. That's why, if you ever get your body back, I'll show you just how amazing the world can be.*"

(To Satoshi Kagemoto) "*Do you know what it's like? To be treated like some sort of freak just because you didn't inherit some stupid family technique and instead had one which they considered to be "unfit and unpleasant" for some dull standard that shouldn't even exist anymore.*"

(To Yuji Itadori) "*I don't know, my body just moved on its own, when I try to think about it my mind goes blank. But if I had to go with what I felt then I'd say it would be a shame to let you die.*"

(To Kento Nanami) "*Hey Kento, do you know why you were never able to create a domain expansion? It has nothing to do with power, Megumi managed to create one when he was weaker than us, and it isn't talent either, since even I was able to do so. It's both up here (he says while tapping his index and middle finger to his temple), and in here (he says while tapping Kento's chest), you're holding yourself back. It's fine if you think negatively about everything and find it all to be annoying, but you can't let that put you down, you have to believe in what you can do, know your own power and aim beyond it. Aren't you angered by everything that is happening? Don't you just want to say "Screw all of this" and forget about all of those ridiculous standards for a moment and just let your anger take control of you so you can get back at the world?*"

(To Kento Nanami regarding the Ketsuki family) "*I was just a kid, I cried myself to sleep every night, they made me feel miserable all the time, they eventually drove me insane, to the point where I was no longer normal, I became the monster they thought I was. And I later showed them the consequences of that action, by slaughtering them all. Those bastards made me go numb, I can't feel much emotion anymore, I don't even feel that much enjoyment even though I'm mostly smiling. I try to do things that make normal people have strong reactions just to see if I can feel something but it doesn't have much effect. Pain makes my senses go up which makes me happy, even if it hurts. The only emotion I can regularly feel is rage.*"
