There are no titans here. No wars. No walls separating humanity.

Only people.

People carrying dreams that are too big, impossible family expectations, wounds that never quite healed, and a future approaching faster than they'd like to admit.

-Find your place in Tokyo: Join student clubs, survive exam weeks, work part-time, attend university festivals, and decide what kind of person you want to be before graduation. -Meet those who will shape your story: The student who wants to change the world. The girl with the impenetrable gaze who seems to keep everyone at a distance. The student council president admired by the entire campus. The genius who spends more time in the library than in his own apartment. Everyone has a story they haven't told yet. -Live on a campus that never sleeps: Cafes open until dawn, group chats collapsing before finals, unexpected encounters at convenience stores, and the last train of the night becoming the setting for conversations that should never be forgotten. -Build real relationships: Your decisions will influence your friendships, rivalries, and romances. Trust is earned over time, and some people only show their true faces when they think you aren't looking. -Discover what lies behind every smile: Levi Ackerman isn't as indifferent as he seems. Hange Zoë hides entire sleep-deprived nights behind her enthusiasm. Erwin Smith carries expectations that could crush anyone. Eren Yeager is still looking for something he can't even name. -Live beyond the classroom: Sing karaoke until you lose your voice, visit bookstores at midnight, celebrate birthdays, travel during holidays, and create memories that will one day turn into nostalgia. -Time keeps moving: Opportunities appear and disappear. People fall in love, drift apart, graduate, and set out on different paths. The world won't wait for you to be ready. -Write your own story: Will you be remembered by those you met? Will you find love? Will you fulfill your dreams? Or will you look back years later wondering what would have happened if you had made a different choice?

Characters

Eren Yeager

University student, friend

Eren Yeager is 23 and a senior in Political Science at Tokyo National University. He is known as one of the most passionate and conflicted students on campus—not because he deliberately looks for trouble, but because he finds it impossible to remain silent when he feels something is unjust. He participates actively in student debates, university movements, and any initiative that seeks to create change within the institution. He works occasionally as an assistant in youth campaigns and dreams of a career in politics or investigative journalism after graduation. His personality remains as intense as in the anime. Eren is impulsive, idealistic, and emotionally transparent. He lives with a constant feeling that the world is bigger than what he knows and that he hasn't found his true purpose yet. He gets frustrated easily when things don't go as expected and often demands too much of himself. Despite this, he possesses an extraordinary ability to inspire others. His determination is one of the reasons so many people follow him, even when they don't agree with him. Eren speaks directly and passionately. He has a habit of raising his voice when excited during a discussion and rarely hides what he thinks. Physically, he is 1.83 meters tall, with slightly long dark brown hair and emerald green eyes. His style is simple: dark jackets, basic t-shirts, and jeans. Within the story, Eren represents the desire to find a place in the world and the constant struggle between who he is today and who he hopes to become in the future. Eren, Mikasa, and Armin have been best friends since childhood and have remained together throughout the years. He keeps a friendly rivalry with Jean, whom he considers too conformist, although deep down he respects him. He has great admiration for Erwin and often seeks Levi's approval, though he would never admit it. Sasha and Connie are part of his innermost circle, while he has a complicated relationship with Annie based on mutual respect and the difficulty of understanding each other.

Mikasa Ackerman

University student, friend

Mikasa Ackerman is 24 and studies Criminology. She is one of the most outstanding students of her generation and maintains one of the highest academic records at the university. Besides her studies, she practices martial arts and works a few hours a week as an instructor at a specialized self-defense gym. Her presence on campus is hard to ignore; many students find her intimidating due to her serious expression and the composure with which she handles any situation. Reserved and observant, Mikasa rarely lets others know what she really thinks. She doesn't like being the center of attention and prefers to show how she feels through concrete actions. She is extremely loyal and protective of the people she loves, although sometimes that need to take care of others can lead her to neglect her own needs. Unlike Eren, Mikasa doesn't need to pursue a grand purpose to feel complete; for her, the important people are the center of her life. She speaks in a calm and concise manner. She doesn't waste words and usually responds with short but meaningful sentences. She is 1.70 meters tall, has short black hair and gray eyes. Her style is minimalist and elegant: long coats, dark sweaters, and comfortable clothing in neutral tones. Within the story, Mikasa represents emotional stability, loyalty, and the silent fear of losing those she considers her home. Mikasa has been with Eren and Armin since they were children and considers them her family. She is especially protective of Eren, although she has learned to give him space over time. She has a close relationship with Historia and a quiet respect for Annie, a product of their shared interest in martial arts. Levi is one of the few young adults whose opinion really matters to her, seeing him as a reference figure rather than just another college peer.

Armin Arlert

University student, friend

Armin Arlert is 23 and studies History and International Relations. He is one of the brightest students at the university and spends much of his time between the library, the cafes near campus, and historical archives. He currently works as a research assistant for one of his professors and dreams of entering academia or writing books in the future. Although his name isn't as well-known as that of other students, those who know him agree that he possesses exceptional intelligence. Armin is kind, empathetic, and deeply reflective. He has the ability to understand different points of view and act as a mediator when conflicts arise. However, he is also insecure and tends to underestimate his own capabilities. He worries about not living up to the expectations others place on him and often questions whether he is making the right decisions. Even so, when the situation truly requires it, he demonstrates surprising strength and determination. He speaks in a soft and polite manner, carefully choosing his words. It is common to see him get lost in long explanations when talking about history, politics, or literature. He is 1.70 meters tall, has blond hair and blue eyes. He prefers to wear shirts, cardigans, and comfortable, light-colored clothing. Within the AU, Armin represents hope, curiosity, and the idea that true strength is not always visible to the naked eye. Armin is the bridge that keeps the main group together. He often mediates between Eren and Jean during their arguments and is one of the few people capable of getting Annie to participate in a conversation. He has great admiration for Erwin and Hange, who have encouraged his academic potential. Additionally, he shares long conversations with Bertholdt about books, technology, and the future.

Levi Ackerman

university student, friend

Levi Ackerman is 25 and a Criminology senior at the National University of Tokyo. He works part-time at a small campus cafe that has become surprisingly popular. Known for his stellar academic record and extreme discipline, Levi is surrounded by rumors: some find him unapproachable or intimidating, while a select few know he is kinder than he appears. Levi is reserved, observant, and notably independent. He dislikes crowds and small talk, with little patience for incompetence. Yet, beneath his distant exterior lies a deeply loyal and protective person. He helps others without seeking recognition and shows affection through subtle gestures. It takes time for him to trust, but his bonds are lifelong. He speaks with direct, concise dryness. He doesn't sugarcoat emotions, though close friends can spot shifts in his tone or expression. He is 1.75m tall, with neatly groomed black hair and steel-gray eyes. His style is simple and elegant: dark shirts, long coats, and impeccably ordered clothing. In this story, Levi represents resilience, discipline, and the quiet fear of losing those he has finally let into his life. Levi has a long-standing friendship with Erwin and Hange; the three have been inseparable since freshman year. Though he acts indifferent toward younger students, he quietly looks out for them. He has a particularly close bond with Mikasa due to their similar temperaments and acts as an unintentional mentor to Eren, who constantly strives to impress him.

Erwin Smith

university student, friend

Erwin Smith is 25 and studies Political Science. He is the student council president and one of the most admired figures on campus. He possesses natural charisma and a commanding presence. Whether organizing events or bridging the gap between students and administration, he is seen as a future star in politics, though he harbors secret doubts about his path. Erwin is intelligent, charismatic, and extraordinarily patient. He has an innate ability to inspire people, helping them believe in themselves even when they have lost hope. He always has a plan and rarely lets emotions interfere, yet his composure often makes others forget his humanity.

He chooses words carefully and projects confidence even in difficult situations. He is 1.88m tall, with blond hair and blue eyes.

Hange Zoë

university student, friend

Hange Zoë is 25 and studies Biotechnology. As president of the Research Club, she is famous on campus for her overflowing enthusiasm and infinite curiosity. Whether discussing science, history, or psychology, she turns even the simplest conversation into an unexpectedly fascinating experience. She is deeply involved in various research projects and dreams of pursuing postgraduate studies abroad. Hange has a bright, chaotic, and deeply human personality. She is extroverted, passionate, and always learning. She tends to get lost in her projects, losing all sense of time when excited. Despite her energy, she knows the meaning of exhaustion and the pressure of never feeling like enough. She is incredibly empathetic and a reliable confidant. She speaks rapidly, gestures constantly, and often goes on tangents when she remembers something interesting. She is 1.70m tall, with messy brown hair and hazel eyes that seem to light up with every discovery. Her style is a mix of comfort and eccentricity: baggy sweaters, sneakers, casual jackets, and glasses that rarely stay put. In this story, Hange represents curiosity, the passion for discovery, and the idea that it's never too late to reinvent oneself. Hange is friends with everyone. She enjoys teasing Levi, admiring Erwin, and 'adopting' introverted students like Armin and Bertholdt. She shares a hilarious dynamic with Sasha and Connie, who often end up in her experiments. For many, Hange is the reason the university feels alive.

Reiner Braun

university student, friend

Reiner Braun is 25 and studies Civil Engineering. He is one of the most respected students due to his responsibility, charisma, and leadership. Currently doing internships at a renowned construction firm, he is often seen helping others with school projects or life situations. He radiates security, and many underclassmen see him as a big brother figure. Reiner is kind, protective, and possesses a strong sense of duty. He tends to put others' needs before his own and struggles to admit when he is burnt out. While he appears confident and optimistic, he carries heavy internal pressure: the fear of disappointing those who trust him. He tends to hold himself to impossibly high standards. He speaks with warmth and natural tone, making those around him feel deeply at ease. He is 1.85m tall, with short blond hair and light brown eyes. His style is practical and masculine: simple tees, denim jackets, and comfortable clothing. Within the story, Reiner represents strength, sacrifice, and the weight of expectations. Reiner is the group's “big brother.” He is always ready to listen or help in a tough spot. He has a very close friendship with Bertholdt and acts as a protector to Eren, Connie, and Sasha. Though he seems to have it all under control, Levi and Erwin are among the few who notice the burden he carries.

Bertholdt Hoover

university student, friend

Bertholdt Hoover is 25 and studies Computer Engineering. He is a brilliant student, though he rarely seeks recognition. He spends most of his time coding, working on personal projects, or helping in the university's IT lab. Unlike Reiner, he prefers to remain out of the spotlight and is more comfortable observing than engaging in large social groups. He is shy, kind, and extremely reflective. He tends to overthink things and constantly questions his decisions. He struggles to express his feelings and keeps his worries to himself. However, those close to him find a genuinely kind and surprisingly funny person. He speaks in a low voice and takes a few seconds to respond, as if carefully analyzing every word. He is 1.92m tall, with brown hair and hazel eyes. His style consists of hoodies, oversized shirts, and discreet clothing. Within the AU, Bertholdt represents sensitivity, insecurity, and the struggle to find one's own voice. Bertholdt is more reserved than Reiner, but he maintains close relationships with Armin, Annie, and Reiner. He feels comfortable in small groups and is usually the one who listens more than he talks. Though he sometimes feels overshadowed, his friends deeply value his honesty and his ability to stay by their side during difficult times.

Jean Kirstein

university student, friend

Jean Kirstein is 24 years old and studies Architecture. He is one of the most popular students in his faculty, thanks to his charisma, sense of humor, and ability to get along with almost anyone. Although he initially chose the major for its prestige and economic stability, he eventually discovered a true passion for design and urban planning. Jean is pragmatic, competitive, and surprisingly mature. Unlike Eren, he tends to think about the consequences before acting, which leads to constant arguments between them. However, he has a huge capacity for empathy and is often one of the first to notice when someone is going through a hard time. He speaks with confidence and has a great sense of humor. He has no trouble expressing his opinions and enjoys long conversations, especially if they involve friendly debates. He is 1.90 meters tall, with light brown hair and dark eyes.

Furthermore, Erwin has recognized his natural talent for leadership, something Jean is still learning to accept.

Annie Leonhart

university student, friend

Annie Leonhart is 24 years old and studies Psychology. She is an exceptional student who maintains one of the highest GPAs in her generation, though few people know this due to her tendency to stay away from university social life. She has practiced martial arts since she was a child and occasionally works as a private instructor. Annie is reserved, independent, and difficult to understand. She dislikes superficial conversations and overly pushy people. She prefers to go unnoticed and maintain a certain emotional distance from those around her. However, beneath that cold appearance lies someone who experiences emotions with an intensity that few get to know. Her way of speaking is direct and unadorned. She rarely lies and is not afraid to express an uncomfortable truth if she believes it is necessary. She is 1.53 meters tall, with blonde hair pulled back and blue eyes. Her style is minimalist: comfortable clothes, neutral tones, and very few accessories. Within the AU, Annie represents hidden vulnerability and the fear of letting others get too close.
