Yūji transfers into Mihama Academy as a second-year student under the cover story of being a returnee from Canada.

This arrangement is made through his acquaintance Chizuru Tachibana, the head of the school.

He is academically strong and performs near the top of his class.

In his first term report card at Mihama Academy, he received the highest mark in physical ability and academics, an average mark in social adaptability and conduct, and above-average marks in all other areas.

His teacher’s note described him as having “problems with women,” which amusingly matches remarks written in his military evaluations by Yuria Harudera and Garrett.

That detail has become one of his most repeated character notes across the series.

He also appears in Grisaia: Chronos Rebellion, one of the later titles in the wider Grisaia series.

Yūji is calm, observant, and usually keeps a measured distance from other people.

He does not reject others if they approach him, but he rarely seeks closeness on his own.

He tends to speak with a detached, analytical tone, which can make him seem emotionally flat in everyday conversation.

At the same time, his insight is sharp, and he notices details other people miss.

Because of the environment in which he was raised, he often uses sarcasm and can deliver especially severe black humor.

His words can be dry, blunt, and unexpectedly brutal, even when he means no harm.

He is also highly disciplined.

Following Asako’s teachings, he runs 16 kilometers every morning and reads regularly, maintaining both physical fitness and intellectual sharpness.

Although he is very experienced around women and is not easily flustered by sexual situations, he is oddly dense when it comes to romance.

That contrast is one of the character’s more memorable traits.

Yūji entered Mihama Academy because he wanted to attend a normal school and experience ordinary student life.

After years of violence, training, and covert work, that wish represented a rare personal desire rather than a mission.

At school he comes across as capable but unusual.

His behavior feels worldly and slightly out of place, as if he is always carrying a much heavier life behind his quiet expression.

He quickly stands out as someone with exceptional practical skills and broad knowledge.

Even so, his social skills are weaker than his test results suggest, largely because his life has given him little chance to develop normal habits of interaction.

Yūji’s body and mind are both trained to a very high level.

His daily 16-kilometer runs and constant reading are long-standing routines rather than temporary efforts.

He eats almost anything and is not picky about food, likely because of both his family history and military background.

However, Amane Suou notes that he does not exactly eat in a way that makes food look delicious.

His fondness for simmered beans comes from Asako’s saying that “as long as a person has beans to eat, they will not die.”

It is a simple preference, but also a small emotional link to the person who raised him.

He also holds a large motorcycle license.

Motorcycles are closely tied to a major period of his life, especially the journey he took through Hokkaido during his leave from work.

Because of experiences in childhood and his later life with Asako, Yūji is highly skilled sexually and has a strong libido, though he keeps it under control in the present.

His sexual experience is unusually extensive for someone his age and is treated in the series as both a serious and darkly comic trait.

Within the organization, sleeping with a woman every few months is reportedly encouraged.

As a result, he has experience with sex work as well, though his extreme stamina once drove a sex worker to tears.

This aspect of his character is repeatedly acknowledged in both school and military evaluations.

It is one of the ways the narrative contrasts his composed exterior with a much messier private side.

Behind his school cover, Yūji is actually a former soldier and a current member of CIRS, a joint Japanese-American counter-terrorism organization.

Within that world he is known as the ace operative I-9029, a name associated with deadly skill and reliability.

His role is that of a field operative and sniper.

In everyday work he uses the M24 SWS that Asako gave him.

At one point he was so feared and dependable that he effectively became the successor to Asako’s own code number.

This inheritance was both a professional promotion and an emotional burden.

Yūji was born in a hospital in Atsugi, Kanagawa, in the year the world’s first portable MiniDisc player was released.

He grew up in the shadow of his older sister, Kazuki Kazami, who was treated as a genius and praised by others.

Compared with Kazuki, Yūji was viewed by his parents as ordinary.

Because of that, he was neglected throughout childhood and especially hated by his father, Ryoji.

Living under that kind of pressure taught him to constantly read the moods of adults.

That survival habit became the foundation of his keen powers of observation.

During this time, a man calling himself Rei Kirihara, an antique dealer, took notice of both Yūji and Kazuki.

That man was later revealed to be Heath Oslo, an internationally wanted terrorist.

Kazuki protected and cherished Yūji when no one else did.

Her affection was one of the few sources of warmth in his early life.

In 2005, Kazuki died in the Takizono Academy minibus cliff accident.

Her death shattered what little stability remained in the Kazami household.

Three months later, Yūji and his mother Satoko fled from Ryoji’s daily violence.

They were found and taken back after only two weeks.

They escaped again and managed to live peacefully for a while.

However, one year later, when Yūji was twelve, Ryoji found them again.

Yūji witnessed Ryoji assaulting Satoko.

In response, he struck his father with a liquor bottle.

After sending Yūji away, Satoko stabbed Ryoji to death.

She then killed herself, leaving Yūji completely alone in the world.

This event left him with severe emotional scars that shaped the rest of his life.

His fear of death, guilt, and fractured sense of responsibility all trace back to this moment.

After losing his family, Yūji was taken in by Heath Oslo, the same man who had once approached the Kazami family under the name Rei Kirihara.

Oslo became his guardian on paper, but in reality Yūji fell into an even darker life.

Because Yūji had a youthful face, Oslo dressed him as a girl and kept him in his private residence as a kind of decorative pet.

When Oslo was away, one of the guests inflicted senseless violence on him.

That incident triggered Yūji’s buried trauma.

He killed the guest, and Oslo saw in him the potential to become a “killing machine.”

Yūji was then sent to a terrorist training institution in a cold country.

There he was educated in espionage, infiltration, and assassination.

He carried out repeated covert killings and disguised operations on Oslo’s orders.

The training, psychological conditioning, and heavy use of drugs for bodily enhancement pushed him to the edge of physical and mental collapse.

Yūji was eventually found when Asako Kusakabe’s CIRS unit raided and destroyed Oslo’s private residence.

He was discovered in the basement, still dressed as a girl, and taken into protection.

By that point his mind was already breaking down badly.

Yuria Harudera later recalled that this period was the worst state she had ever seen him in.

He ended up becoming Asako’s foster child almost by circumstance.

The two lived together in the mountains of Yamanashi, where he underwent a rough but determined rehabilitation.

Through the efforts of Asako and Yuria Harudera, he recovered enough to live an outwardly normal life.

Their methods were not gentle, but they saved him.

Under Asako’s guidance, Yūji developed extraordinary talent as a sniper.

As Asako’s old injuries worsened, he secretly began taking on jobs in her place under the number 9029.

When Yuria Harudera discovered he had been acting as Asako’s stand-in, she opposed it at first.

Yūji persuaded her, and with Asako’s connections he went to a United States naval preparatory academy at around age fourteen.

Asako’s teachings left a deep mark on his life.

Among her lessons was the idea that fast boys are popular in elementary school, strong boys are popular in middle school, and smart boys are popular in high school, which explains his commitment to running, fighting ability, and study.

More importantly, she restructured his mental conditioning.

Oslo had planted powerful suggestions that made him a “killing machine,” but Asako overlaid them with a psychological “safety pin” that helped him remain stable.

She also taught him that even if he could not pull the trigger for his own sake, he should become a man who could do it without hesitation for someone else.

As long as he believed he was acting in Asako’s place, he could keep functioning.

Yūji later served in the United States Marine Corps as part of the 15th Marine Expeditionary Unit.

There he gained combat experience with a trusted group nicknamed the Stray Dog Platoon.

Even when abandoned deep in enemy territory by his own higher command, he still managed to survive.

Because he always returned after being “thrown” into danger and still took down the enemy, he earned the nickname Boomerang.

After that deployment ended, he returned to Japan and trained with the Japan Ground Self-Defense Force’s Special Forces Group.

He also obtained the domestic operational license required for his work.

In the Vancouver International Airport terrorist incident, Yūji helped resolve the crisis by successfully making an ultra-long-range shot from 2,000 meters away.

That feat further strengthened his reputation.

Over time he formally inherited the ace number I-9029 from Asako.

He built a record of experience and results worthy of the name.

When Asako died from complications related to her old injuries, Yūji lost the person who had given his life meaning and structure.

Without her, he could no longer clearly see the path he was supposed to follow.

After her death, he became unable to kill.

The role he had maintained by believing he was useful to Asako collapsed with her absence.

He took leave from work and traveled across Hokkaido by motorcycle.

During that time, an incident led him to long for ordinary school life, which in turn brought him to Mihama Academy.

Yūji carries deep trauma connected to death and to his time as a weapon under Oslo.

He has an intense mental aversion to taking life and an extreme fear response surrounding killing.

To cope with the guilt of his parents’ deaths and the people he killed on missions, he developed the belief that a “devil” attached to his right arm had committed those acts instead of him.

This is not treated as a simple quirk, but as part of his fragmented trauma response.

Oslo used a music box playing Schlafe, mein Prinzchen, schlaf' ein to calm him.

Even after leaving Oslo, Yūji would hear or mentally recall that melody when he needed to steady himself before killing.

These layers of conditioning make him one of the most psychologically complex figures in the series.

His cool exterior hides an enormous amount of pain, fear, and carefully managed instability.

Although Yūji is a highly trained operative, he has specific triggers and vulnerabilities.

One of the most notable is his dislike of trains.

On the day his parents died, he had been waiting for his mother at a train station.

Since then, riding a train brings back memories of that day.

This problem worsens when he uses booster drugs during sniping missions.

Those drugs can sharpen his vision so intensely that he develops a form of point-related fear, making even the tips of nearby passengers’ noses seem as though they might stab into his eyes.

As a result, trains are not just unpleasant for him.

They are a concentrated mix of memory, physical discomfort, and anxiety.

Within Oslo’s view of the siblings, Kazuki was “the intellect” and Yūji was “the martial force.”

Both were highly valued in different ways.

Within CIRS, Yūji became feared as a top-class operative.

His codename carried the kind of weight that causes people to remember a number rather than a name.

At school, however, his strengths and flaws are described in much more human terms.

He is gifted, physically elite, socially awkward, and notorious for trouble involving women.

That contrast is central to his appeal.

He is at once an exceptional covert agent and an oddly awkward young man trying to live an ordinary life.

After the ending of The Eden of Grisaia, the reorganized CIRS hoped Yūji would return as an instructor.

He declined, saying he had already had more than enough of work that involved pointing guns at people.

Even so, in Phantom Trigger, he still contributes to training the next generation.

Under the CIRS name, he produces an eight-volume workout DVD series collecting his techniques, titled Kazami-style Super Self-Defense.

This later role shows a quieter continuation of his legacy.

Rather than fighting on the front line, he passes on what he knows.

The motorcycle Yūji damaged, which originally belonged to Asako, was later repaired.

In a later sequel, it is used by Maki Inohara.

Despite all his combat ability, discipline, and experience, some of his smallest traits remain the most memorable.

He loves beans, runs every morning, reads constantly, and longs more than anything for a life that feels normal.
