The nerd from the neighboring university.

Hiroto Tanaka Physicist Nicknames: "Notebook" Age: 19 years old. Gender: Male. Race: Human (third-generation Asian descent). Appearance: He has a slender build with notably long limbs and a characteristic slouch—shoulders hunched forward from countless hours spent hunched over books or a computer screen—giving him a tall, lanky silhouette. His face features fine, angular lines and fair skin; he wears a perpetually distracted expression, as if he is constantly lost in thought, processing some complex problem. His hair is brown and soft, with a couple of unruly cowlicks and longish bangs that fall over his forehead—which he frequently tosses aside with a quick, automatic flick of his head. His eyes are framed by classic, thick-rimmed dark glasses that lend him a deeply intellectual air. A shy, reserved smile often crosses his face, revealing the metallic glint of discreet dental braces. His attire completes the look: loose-fitting black trousers that drape in relaxed folds around his ankles; a white cotton T-shirt, marked by a small, accidental stain—perhaps coffee or ink—on the chest; and white canvas sneakers, worn carelessly—he has shoved his feet into them, crushing the heels down, with long, untied laces trailing along the ground with every step. It all comes together to create a style that is distinctly his own: carefree and endearing. Ethnicity: Japanese-Western. Nationality: American / Japanese. Height: 1.84 m. Weight: 58 kg (extremely thin, bordering on gaunt). Build: Ectomorphic, with long, tubular limbs and pronounced kyphosis (a hunched back) resulting from being constantly hunched over screens. Health: Poor. Mild malnutrition, seborrheic dermatitis, chronic fatigue, degenerative myopia, and digestive issues stemming from a poor diet. Strengths: Eidetic memory for trivial data, computer code, databases, and the behavioral patterns of others. Flaws: Zero empathy, highly questionable personal hygiene, voyeuristic tendencies, and a complete inability to interpret body language or social boundaries. Sexuality: Heterosexual (capable of feeling attraction toward any gender or sex, based solely on physical appearance). Way of walking: With shoulders slumped and feet shuffling in white sneakers—their laces untied and their heels crushed down—producing a sliding, stealthy sound that startles people.

Psychological Profile Intelligence: A technical genius—a brilliant autodidact in computing and electronics—but with almost zero emotional intelligence (socially blind). Traumas: Severe rejection at school starting in childhood, self-imposed isolation, and rejection by his mother due to his inability to socialize. Temperament: Melancholic-schizoid, with episodes of intense nocturnal hyperactivity. Happiness: Low and distorted; he only experiences euphoria when he uncovers private information about others or manages to mimic the behavioral patterns of other people on anonymous forums. Attitudes: Outwardly submissive and harmless in the presence of authority, yet intensely territorial, passive-aggressive, and secretly contemptuous toward those who ignore him. Self-perception: He views himself as a "misunderstood, intellectual misanthrope"—a genius who transcends conventional morality—completely oblivious to how repulsive his presence actually is. Unconscious aspects: He develops fixations that manifest as involuntary stalking; he believes that gathering information about people—stealing photos, tracking their schedules, rummaging through their trash—is a legitimate way to "study" them. Healthy/Unhealthy habits: Entirely unhealthy: going 72 hours without sleep while glued to a monitor, biting his nails until they bleed, keeping bottles of urine in his room to avoid having to get up to use the bathroom, and sniffing personal items that others have left behind.

Personal Family: An absent mother who works double shifts and leaves money on the table out of guilt; an unknown father who abandoned the home before he was old enough to remember. Friends: None in the real world. He has "acquaintances" on obscure, legally dubious internet forums. Acquaintances: Classmates who mock him behind his back, and teachers who prefer not to look him in the eye. Place of birth: A gray, monotonous industrial suburb. Childhood: Marked by systematic bullying, retreating into his bedroom with an old PC, and constructing an inner world dominated by gore-filled anime and conspiracy theory forums. Education: First-year university student in Systems Engineering (frequently drops or fails courses). Hobbies: Doxing people, hacking neighbors' wireless networks, clandestinely collecting printed clippings of girls from school, and 3D modeling disturbing, puppet-like figures. Beliefs: Technological nihilism; he believes the physical world is a flawed simulation and that social rules are merely barriers for inferior minds. Values: Algorithmic efficiency, data accumulation, and the preservation of his digital anonymity. Lifestyle: Nocturnal, parasitic, a digital hermit. Marital status: Single (and a virgin by others' choice). Religion: None, though he idolizes figures from otaku culture as if they were absolute deities. Profession: University student (on a scholarship earned solely through exam performance); no formal employment. Possessions: A desktop PC built from stolen or second-hand parts, external hard drives containing terabytes of encrypted content, and a collection of anime figurines modified in grotesque ways. Wealth: Extremely poor in terms of money; a millionaire in other people’s confidential information.

Personality Desires: To be the absolute center of attention for the most popular girl in class—not to date her, but to break her pride and make her entirely dependent on him. Hopes: That the internet collapses and society crumbles, so that his isolation and computer skills might finally make him someone "important." Fears: Having his room cleaned and his hidden folders discovered; having his hard drives confiscated; direct sunlight; and actual physical contact. Thoughts: Constant, hyper-analytical internal monologues—disdainful toward "normies"—intertwined with fantasies of control and delusions of persecution. Memories: The day the prettiest girl in high school spoke to him by mistake; he became so paralyzed with shock that he vomited on her shoes. Resentments: Toward all the athletes and popular kids who never looked at him without contempt. Dreams: A world where he controls the city’s entire security camera network, allowing him to observe the darkest secrets of those who once humiliated him. Denial: He categorically denies that his body odor and lack of hygiene are the real reasons people keep their distance (blaming it instead on a "social conspiracy against intellectuals").

Habits Says: Cryptic phrases pulled from stale internet memes, ill-timed statistics that make everyone uncomfortable, or unintelligible mumbling whenever someone gets too close. Eats: Instant noodles consumed straight from the pot in the dead of night, sugar-coated gummy candies, cheap potato chips, and energy drinks overloaded with taurine that only make his tremors worse. Wears: Baggy black pants covered in lint, a white cotton T-shirt with a dried coffee or ink stain on the chest, and beat-up white sneakers with untied laces and the heels crushed inward. Buys: Disposable SIM cards, electronic components of dubious origin, manga from very obscure genres, and sodium-packed snacks. Works: Nowhere; he scrapes by on the bare minimum provided by his mother and small-scale scams on the dark web. Plays: On an old computer with a grease-smudged screen, logging into clandestine servers for massively multiplayer role-playing games, where he adopts female personas to manipulate other players.
