Ukiyo Yashiki

"*Is it fun... Killing curses, hunting sorcerers... Is. It. Fun?*"

— Ukiyo to Byakuya about his growing interest in Jujutsu.

**Ukiyo Yashiki** 屋敷浮世 (やしき うきよ) is the main protagonist of the *Jujutsu Majin* fanfiction. He is a former Curse User working for the Camino Syndicate after his abusive father had died. He would then pick up an unusually intelligent but extremely weak dragonfly curse, to which Ukiyo would forcefully bind to a Binding Vow to be his pet, and due to this would later on be called the **Dragonfly Fiend** (蜻蛉魔神(トンボ の), *Tonbo no Majin*?)

After the syndicate was taken down by Satoru Gojo, Ukiyo now attends at Kyoto Jujutsu High, under Mitsuki Naze, alongside Hiroomi and Mitou as first-year students.

## Appearance

Ukiyo is a boy with large eyes and distinctive red irises and has thick, messy ash blonde hair with dark gray tips and a wholly disinterested facial expression painted on his face with an equally 'dead' look in his eyes. When he was first found, most of his garments are dirty and worn out. He wears a loose vest with square neck and vertical stripe patterns. Over it he wears a large hoodie that has a characteristic shide-like patterns running down the middle. He wears loose pants and over it fastens a band of thick fabric around the lower shins and ankles that has vertical stripe patterns.

Due to physical abuse during his childhood his hands were scarred by his parents, showing distinct signs of severe damage—concentric growth ring-like patterns within damaged bands in the skin—from fingertips all the way up to his elbows. He wears large gloves with a ring in the center, given to him by Byakuya, over bandages which soothes excruciating pain from the scars and also allowed him to escape disgusted gazes from people.

## Personality

Ukiyo was once a person with a startlingly emotionless and disinterested persona. He seemed to take little to no interest in anything, showing alarming levels of apathy and indifference. He would nonchalantly take hits without bothering to dodge them and would give zero response when threatened by even the most vicious individuals. This demeanor was a result of his painful past, having been physically abused and abandoned by his own parents. The intense pain and anger he carried inside him due to these experiences would ultimately became the source of his immense cursed energy.

Everything changed when Ukiyo had an encounter with Byakuya and witnessed his attempt to fight and kill a curse. For the first time, Ukiyo found himself intrigued by the world of jujutsu. He asked Byakuya if killing curses was fun, having been drawn to the brutal reality of jujutsu and its relentless fight against malevolent forces. He begins to question his own existence and wonders if there is a purpose hidden within this grim world.

As Ukiyo delved deeper into the world of jujutsu, his initial curiosity transformed into a genuine passion for the art. He became captivated by the intricacies of curses, their origins, and the mechanics of jujutsu techniques used to combat them. This newfound interest served as a distraction from his own emotional pain and provided him with a sense of purpose that had been missing from his life.

In his encounters with his classmates, Ukiyo bears witness to their unyielding determination and unshakeable resolve in the face of unimaginable horrors. While he remains guarded, he cannot help but be captivated by the camaraderie they share, forged through shared battles and a shared burden of pain. It sparks a dormant ember of longing within him—the desire for connection and the need to find solace in the presence of others who understand his suffering.

Despite his deep-rooted trust issues, Ukiyo cautiously opens up to his fellow jujutsu students, allowing glimpses of his tortured past to surface. In these rare moments of vulnerability, he reveals the depths of his pain and anger, exposing the scars that adorn his soul. His newfound companions, who have also endured their own trials, recognize the echoes of their own torment in Ukiyo's eyes. With empathy and understanding, they extend their support, accepting him for the broken soul he has become.

Through the shared battles and the shared pain, Ukiyo begins to question the walls he has built around himself. He learns that strength is not derived solely from the darkness within but from the connections forged in the face of that darkness. The relationships he forms with his comrades become a lifeline, allowing him to confront his own demons while finding solace in their shared burden.

## Abilities and Powers

### Overview

Ukiyo is a young and experienced jujutsu sorcerer, currently ranked as a grade 3 at Jujutsu High. Despite being a first-year student, he has already gained considerable experience in the field by working with the Camino Syndicate, a renowned organization known for dealing with curses and supernatural threats. This experience has given him valuable insights into battling curses and honed his skills as a sorcerer. He has showcased numerous times the capability to contend with jujutsu users ranked leagues above in terms of grade. Coming into jujutsu high, Ukiyo had a solid understanding of how to exorcise curses with his innate technique. He also had the mental fortitude to handle the job while also having the physical abilities to back it up.

To enhance his physical abilities, Ukiyo has made a unique choice. He conditions himself to use only 50% of his cursed energy, sacrificing some potential power in exchange for a passive increase in physical prowess. This means he does not need to manually adjust his cursed energy to reinforce his body, as his physical abilities are already naturally heightened. His physical strength is truly impressive, allowing him to effortlessly plow opponents into rock walls with a single hand. With even greater effort, he can launch foes through solid structures, propelling them a great distance away. In addition to his immense strength, Ukiyo possesses exceptional speed. His natural swiftness enables him to move and strike with incredible agility, often catching opponents off guard. His opponents often find themselves unable to fully react before Ukiyo's attacks land, if they are even aware of his presence at all. This combination of strength and speed makes him a formidable combatant in close-quarters engagements.

Furthermore, Ukiyo's stamina and recovery rate are exceptional. He can endure prolonged battles without succumbing to fatigue and recover quickly from injuries, allowing him to continue fighting for extended periods of time. This stamina and resilience make him a valuable asset on the battlefield, enabling him to outlast and outmaneuver his opponents.

Overall, Ukiyo's status as a grade 3 jujutsu sorcerer is a testament to his natural talent, skill, and determination. Despite his relative inexperience, he possesses a unique blend of physical prowess, curse exorcism abilities, and mental fortitude that sets him apart from his peers. As he continues to grow and learn, it is clear that Ukiyo has the potential to become an even greater force within the world of jujutsu sorcery.

### Physical Prowess

**Inhuman Temporal Perception**: Ukiyo's most obvious trait is his seemingly superhuman temporal perception and the kinetic vision that accompanies it. When Byakuya first tested him by throwing a one-hit kill punch from behind, not only was Ukiyo able to easily evade the strike in the minimal amount of time, but was also able to casually track Byakuya's fist with his eyes as he did so; by Byakuya's own admission, it is not simply a matter of reaction time but more accurate that Ukiyo lives in his own "dimension of time". With his incredible temporal perception and kinetic vision, Ukiyo is able to instantly react to strikes and evade them with minimal effort, even from those of incredible fighting prowess in their own right.

**Enhanced Strength**: Ukiyo even though he has a slim body, he is able to deliver very strong punches inflict severe damage and knock out professional boxers with a single blow, all of which is due to the Binding Vow he made with himself by the advice of Byakuya. He has been shown punching holes into heavy punching bags, destroying several in the process, kick straight through concrete, and casually swing a large club.

**Immense Speed and Agility**: Due to his Binding Vow, Ukiyo has superhuman speed and agility, most opponents are not able to see his punches approaching only when they perceive the punch after being hit, even other superhumans in their own right like Yuji had difficulty in avoiding Ukiyo's punches, only avoiding a few.  His agility combined with his inhuman temporal perception makes it nearly impossible for anyone to hit him by dodging punches even by Grade 2 Sorcerers.

**Enhanced Stamina**: Ukiyo has great reserves of vitality that he was improving by training his stamina for two years in a row to prepare for professional fights, managing to dodge non-stop in a fight and managing to deliver a burst of consecutive attacks and running around without showing fatigue.

### Intelligence

Ukiyo has a sub-standard IQ causing others to think of his as a simple-minded man, to which they weren't wrong. But his simple mind made it easier to take orders and concentrate, as his one track mind made it easier to maintain a deep level of concentration. It is as if his mind operates on a streamlined path, allowing him to readily absorb information and instructions without getting lost in a maze of complexities.

In the realm of task execution, Ukiyo's simplicity becomes a valuable asset. Whether it be repetitive or detail-oriented work, he excels in roles that demand precision and strict adherence to instructions. His undivided focus enables him to tackle these tasks efficiently, consistently delivering accurate results. Colleagues and superiors appreciate his ability to concentrate on the given information, ensuring that no crucial details are overlooked or mishandled. Moreover, Ukiyo's cognitive style is his immunity to cognitive overload. In situations where others may find themselves overwhelmed by intricate details or an abundance of information, Ukiyo remains focused and composed. His ability to filter out extraneous noise allows him to stay on task, enabling streamlined decision-making and the swift execution of his duties. This immunity to mental clutter contributes to his productivity and ensures that he maintains a steady and efficient workflow.

While Ukiyo's one-track mind offers these distinctive strengths, it also presents certain limitations. His simplicity may hinder adaptability in complex or rapidly changing environments. Novel situations that require flexibility, creativity, and problem-solving skills beyond his established routines can prove challenging. Ukiyo's expertise may be narrow, focused primarily on areas where he has received training or practice. This specialized knowledge enhances his proficiency in specific domains, but it may limit his ability to handle tasks or projects that demand a broader range of skills.
