Haruka Sakurai, widely recognized as Prisoner No. 001 in the immersive music project MILGRAM, celebrates his birthday on June 22. Born in 1997, his character is a cornerstone of the project’s complex narrative, representing the deep psychological scars left by neglect and the desperate human need for recognition. As the first prisoner introduced to the audience, Haruka sets a somber tone for the series, weaving a story that explores the thin line between innocence and guilt, and the tragic consequences of systemic failure.

The Specifics of Haruka Sakurai’s Birthday and Identity

Haruka Sakurai was born on June 22, 1997, in Nagaoka City, Niigata Prefecture. In the context of the MILGRAM project, which began its serialized releases in 2020, Haruka is consistently portrayed as 17 years old, a frozen age that reflects the timeline of his incarceration and the events leading up to his judgment.

Identifying as a male with blood type AB, Haruka stands 174 cm tall. His zodiac sign is Cancer, which often carries traits of emotional depth, sensitivity, and a strong connection to home and family—traits that are twisted into tragic ironies within his specific backstory. His image color is a deep ultramarine blue (#0040E8), a hue that mirrors the melancholic and isolated nature of his personality.

The MILGRAM Project Framework

To understand the weight of Haruka’s character, one must understand the MILGRAM project itself. Conceived by Takuya Yamanaka and DECO*27, MILGRAM is an interactive multimedia experience where the audience acts as "Es," the prison guard. The prisoners are all murderers, but the specific circumstances of their crimes are revealed through music videos. The audience then votes whether the prisoner is "Innocent" or "Guilty." These votes directly influence the character's fate and the music produced for subsequent trials. Haruka, as the very first prisoner, was the initial test of the audience’s moral compass.

The Symbolism of the Linden Arrowwood

The birth flower associated with Haruka Sakurai’s birthday is the Linden Arrowwood. In the language of flowers, this plant carries multiple meanings, including "union," "love is stronger than death," and, most poignantly, "do not ignore me."

The latter meaning is particularly significant to Haruka’s arc. The Linden Arrowwood produces bright red fruits specifically to attract birds; if it fails to attract attention, its seeds cannot be distributed, and it effectively "dies" in a reproductive sense. This biological necessity for attention perfectly mirrors Haruka’s psychological state. His entire life was a desperate, failed attempt to be seen, culminating in the horrific acts that led him to MILGRAM. The "Mors Certa" (Death is Certain) inscription on his sash further reinforces the fatalistic nature of his existence, derived from the Latin phrase Mors certa, hora incerta (Death is certain, its hour is uncertain).

A Detailed Look at Haruka’s Backstory

Haruka Sakurai’s tragedy began long before his crimes. Since childhood, he exhibited developmental delays, growing and learning at a pace much slower than his peers. His parents, rather than seeking specialized support or adapting their parenting to his needs, initially responded with overprotectiveness. However, this was not a nurturing form of protection; it was an attempt to hide what they perceived as a deficiency.

By the time Haruka reached the age of 15, the gap between him and other teenagers was undeniable. He struggled with basic literacy, particularly Kanji, which is a fundamental requirement for functioning in Japanese society. At this breaking point, his parents’ attitude shifted from overprotection to total indifference. They began to act as if Haruka did not exist. This shift from being smothered to being invisible is the catalyst for his descent into violence.

The Escalation of Violence

Driven by a pathological need to be noticed, Haruka began hurting and killing small animals. It started with insects, then mice, and eventually escalated to neighborhood pets like cats and dogs. For Haruka, these acts provided a dual satisfaction:

  1. A Sense of Superiority: He felt that these creatures were the only living things "lower" or more "worthless" than himself.
  2. Emotional Connection: When he saw pet owners crying over their lost animals, he felt a twisted sense of connection to the world. Their grief was a direct result of his actions, proving that he had the power to affect others.

The Final Crime

The climax of his escalation occurred on the day of a fireworks festival. Haruka targeted a small child who had become separated from their parents. He strangled the child to death, not out of hatred, but out of a desperate desire for the "excitement" and "attention" that would follow. When he was eventually caught and interrogated, the intense focus the police placed on him—and the horrified looks on his parents’ faces—gave him a surge of euphoria so intense that he fainted. It was the only time in his life he felt truly "important."

Analysis of Haruka’s First Trial: Weakness

In the first trial, the music video for "Weakness" (also known as "Yakiniku Formula") introduced the audience to Haruka’s fractured psyche. The lyrics and visuals are a chaotic blend of childish innocence and disturbing reality.

Lyrical Themes

The song reflects Haruka’s low self-esteem and his perception of the world as a place where the weak are eaten by the strong. He views himself as the "weakness," yet he attempts to justify his actions as a way to survive or be recognized. The repetitive, almost nursery-rhyme-like structure of some verses highlights his stunted emotional development.

Visual Cues

The MV is filled with imagery of forests and abandoned spaces, which were later identified as the scenes of his crimes. The presence of the forest suggests the isolation he felt and the "wild" state his mind reverted to when seeking attention. Despite the dark undertones, the audience voted Haruka Innocent during the first trial. This decision was largely based on sympathy for his developmental disabilities and the perceived failure of his parents and the educational system to protect him.

Analysis of Haruka’s Second Trial: All-Electric Brain

Following his "Innocent" verdict, Haruka’s behavior in the prison changed significantly. He became more talkative, even cheerful, but this change was superficial and unstable. The second trial song, "All-Electric Brain," reflects a much more disturbing reality.

The Shift in Tone

"All-Electric Brain" is frantic and sensory-overloading. It represents Haruka’s realization that he had been "forgiven" by Es and the audience. However, instead of leading to rehabilitation, this forgiveness validated his belief that his actions were acceptable as long as they gained him attention. The song highlights his inability to process guilt in a conventional way; instead, he becomes obsessed with the "love" he receives from the guard.

The Guilty Verdict

The mood of the MILGRAM audience shifted during the second trial. As Haruka’s dependence on Es grew into a suffocating and dangerous obsession, the community began to see the danger he posed to himself and others. The realization that he had killed a second child—something hinted at in his interrogation records—sealed his fate. The audience voted him Guilty with a narrow margin (approximately 54.97%).

The Consequences of Being Guilty

In the MILGRAM universe, a "Guilty" verdict has physical consequences for the prisoners. Haruka’s condition deteriorated rapidly after the verdict. The psychological weight of the judgment, combined with his existing instabilities, led to his status being marked as "Deceased" following the end of the second trial.

This outcome sparked intense debate within the MILGRAM community. Some argued that Haruka was a victim of his circumstances who needed help, not judgment, while others maintained that his crimes were too heinous to overlook, regardless of his mental state. His death serves as a haunting reminder of the project's high stakes.

Psychological Profile: Developmental Disorders and Borderline Intelligence

Critics and fans often analyze Haruka through the lens of developmental psychology. His symptoms align with Borderline Intellectual Functioning (BIF) or a specific developmental disorder that affects social cognition.

  • Lack of Empathy: Haruka struggles to understand the value of life in an abstract sense. He views life as a hierarchy where he is at the bottom, and he kills to move up or to make his presence felt.
  • Attention-Seeking Behavior: His actions are a textbook example of "negative attention is better than no attention."
  • Hyper-fixation: His obsession with the guard (Es) suggests an insecure attachment style, likely stemming from his parents' abandonment.

Haruka’s Relationships Within MILGRAM

Despite his social difficulties, Haruka did interact with other prisoners, though these relationships were often strained or misunderstood.

  • Relationship with Es: Es is the center of Haruka’s world. He views Es as a savior and a parental figure, which makes the "Guilty" verdict even more devastating, as he perceives it as a personal betrayal from the only person who "looked at him."
  • Interaction with Amane: Haruka mentioned that he struggled to deal with children around Amane’s age (Prisoner 010), which is a clear reference to the age of his victims. His discomfort around her highlights the latent guilt he tries to suppress.
  • Relationship with Shidou: The prison guard Shidou noted Haruka’s habit of digging his nails into his palms when tense—a physical manifestation of his internal anxiety.

Trivia and Hidden Details

For the dedicated MILGRAM fan, Haruka Sakurai’s character is rich with trivia that adds layers to his birthday and personality:

  1. Food Preferences: He loves hamburg steak, omurice, and cotton candy. Interestingly, cotton candy was the most expensive thing he ever bought for himself, a choice that reflects his childlike mindset.
  2. Language Skills: Haruka is unable to speak or understand any language other than Japanese, emphasizing his limited exposure and educational background.
  3. Physical Strength: Despite his fragile appearance, Haruka was ranked fourth in an imaginary arm-wrestling contest among the prisoners, suggesting a surprising amount of physical strength (likely used during his crimes).
  4. Sleeping Habits: Haruka sleeps whenever he is bored, a defense mechanism to escape a reality where he feels ignored.
  5. Greatest Fear: His biggest fear is betrayal, which explains his extreme reaction to the Guilty verdict.

What is the Impact of Haruka’s Story?

Haruka Sakurai’s story is a critique of a society that discards those who do not fit the standard mold of productivity and intelligence. By focusing on a character born on the cusp of the summer solstice (June 22), the MILGRAM project highlights a life that should have been full of light but was instead consumed by shadows.

His character challenges the audience to ask: Can someone be held fully responsible for their actions if they were never given the tools to understand them? Haruka’s death marks a tragic end to the first prisoner's journey, but his influence remains as the community continues to judge the remaining inmates.
