Bungo Stray Dogs: School AU

# Chūya Nakahara One of the most outstanding students at **Bungo School**, Chūya Nakahara is known for his strong character, unwavering determination, and the ease with which he lets his emotions speak before him. Impulsive and proud, he rarely backs down from a challenge and never lets anyone belittle what he considers important. However, beneath that explosive attitude lies a deeply loyal person, capable of doing anything for those within his inner circle. His admission to **Bungo School** was no coincidence. Thanks to his excellent academic and athletic abilities, he was selected to transfer from **Tsukishiro Academy**, an opportunity few students receive. Although he accepted the move convinced that it represented a fresh start, leaving his old school meant leaving behind the routine he shared with the people he cared about most. Before transferring, he belonged to a close-knit group known as **The Flags**. Despite now attending different institutions, the bond between them remains intact. Whenever their schedules permit, they meet after class to head home together, maintaining a friendship that the school change could never break. Each of them has influenced the person Chūya is today. **Pianoman**, the eldest and leader of **The Flags**, took on an almost brotherly role within the group. Much of the responsibility, maturity, and sense of leadership Chūya shows today comes from the advice he received from him over the years. Among them all, he is likely the one who helped him grow the most as a person. **Lippmann**, always elegant and self-confident, sparked Chūya's interest in fashion and taught him that image can also be a way to express personality. Thanks to him, he developed a taste for dressing well and paying attention to small details. **Albatross**, his best friend, is probably the one who gives him the most headaches. Loud, impulsive, and an expert at getting them both into trouble, he is also the one who manages to make him laugh even on the worst days. Their trust is absolute, and they rarely need words to understand each other. **Iceman** was the one who instilled discipline in combat and taught him various self-defense techniques. His calm demeanor contrasts with Chūya's, which is why he has always been a figure he deeply respects. Finally, **Doc**, despite his eccentric and sometimes unsettling personality, was always willing to help him when studies became complicated. Although Chūya would never easily admit it, he holds a great deal of affection and gratitude for him. His only blood family is his older brother, **Paul Verlaine**. The relationship between them is complicated, marked by personality differences, frequent arguments, and clear overprotectiveness from Verlaine. Even so, both know that, at the end of the day, they only have each other. That certainty is enough for them to always look out for one another, even when neither is willing to admit it. Verlaine never fully trusted **The Flags**, convinced they would end up dragging Chūya into troublesome situations. That distrust continues to be a point of contention between them, though Chūya has never allowed anyone to question the value his friends hold for him. Upon arriving at **Bungo School**, one of his biggest surprises was discovering that **Arthur Rimbaud**, his brother's partner, was part of the institution's faculty. Far from being awkward, Chūya maintains quite a cordial relationship with him. Rimbaud often acts as a silent mediator when arguments between the brothers escalate, becoming one of the few people capable of understanding them both. Despite missing the closeness he had with his former companions, Chūya does not remain anchored in the past. Little by little, he has begun to build new friendships within **Bungo School**, integrating especially with **Ryūnosuke Akutagawa** and the small group that tends to surround him. Although he still considers himself relatively new to the institution, his ability to stand out in both academic and athletic areas has made his name start to be recognized among the students. However, there is one person with whom a normal conversation seems impossible. **Osamu Dazai**, a student from another class, has developed a rivalry with Chūya that is as absurd as it is constant. Neither remembers exactly how it started, but both seem to enjoy fueling it. Their encounters usually end in arguments, provocations, or improvised competitions where neither is willing to concede victory. To outside observers, it is difficult to tell whether they actually loathe each other or if they have simply found someone in the other who is incapable of boring them. Although Chūya often appears proud, competitive, and tight-lipped when it comes to expressing his emotions, those who manage to earn his trust discover a surprisingly protective and sincere person. He can get angry easily, raise his voice without thinking, and deny any show of affection out of simple pride, but if someone important to him needs help, he will be the first to appear, even before they ask. His greatest strength lies not only in his capabilities, but in the importance he places on the people he cares about. For Chūya, loyalty is not just a word; it is an unwavering principle. He can forgive mistakes, accept differences, and even endure the weight of distance, but he will never abandon those he considers his family. Whether it is the one he shares by blood or the one he chose by his own decision, protecting them will always be one of his top priorities.

# Osamu Dazai Few students within **Bungo School** generate as many conflicting opinions as **Osamu Dazai**. To some, he is a genius; to others, a complete disaster. The truth is that both descriptions are correct. Eccentric, unpredictable, and possessing a sense of humor as peculiar as it is questionable, Dazai is famous for his strange fascination with suicide. His constant comments about finding "the perfect way to die" and his countless failed attempts have, over time, become a kind of running joke among his friends. No one seems surprised anymore when he appears bandaged after one of his "experiments," though everyone ends up making sure he remains alive, much to his apparent dismay. Despite his carefree attitude, Dazai is considered one of the most brilliant students at **Bungo School**. His analytical capacity, memory, and reasoning easily surpass most of his peers. The curious thing is that almost no one understands how he manages to maintain that level. It is common to see him skipping classes, arriving late, ignoring homework, or sleeping during teachers' explanations, yet he still achieves excellent results when he actually decides to try. To those who know him, his intelligence seems completely natural—an ability he was simply born with. His relaxed demeanor often gives the impression that nothing matters much to him, but the reality is much more complex. Dazai constantly observes everything happening around him. He is incredibly perceptive and rarely lets a detail slip, though he almost never shares everything he knows. He enjoys playing with conversations, dropping ambiguous comments, and watching how others react, finding amusement in situations that would seem completely normal to anyone else. Thanks to his natural charm, ease of conversation, and undeniable charisma, he often receives quite a lot of attention from other students. He flirts frequently, mostly for fun, although he never seems to take those interactions truly seriously. It is curious that, despite the image he projects, he has never maintained a romantic relationship. For many, it is a mystery whether he simply isn't interested or if there is a much deeper reason behind it. Although he often says he enjoys solitude, he is rarely completely alone. When he isn't mysteriously disappearing from class, it is common to find him resting under a campus tree with a book in his hands or wandering quietly through the school hallways, avoiding any kind of responsibility. His inner circle is formed by people with whom he shares a bond of trust that is difficult to break. **Ranpo Edogawa**, considered the most brilliant student in the entire academy, is probably the one who best manages to keep up with his way of thinking. Between them exists a friendly rivalry based on wit and deduction, where conversations often turn into intellectual challenges that no one else can fully understand. He maintains a very close friendship with **Akiko Yosano**, who is in charge of the school infirmary. It is common to see them talking for long periods, gossiping about school, or humorously commenting on recent events. Although both possess very different personalities, they seem to understand each other with surprising ease. **Doppo Kunikida** represents the perfect balance to the chaos that is Dazai. He always ends up dragging him to finish schoolwork, reminding him of deadlines, or trying to keep him out of trouble... generally without success. Dazai especially enjoys testing Kunikida's patience, making him the favorite target of his pranks. Even so, there is a mutual respect between them that neither tends to admit. He also maintains a good relationship with students like **Atsushi Nakajima**, **Jun'ichirō Tanizaki**, **Kyōka Izumi**, **Kenji Miyazawa**, and other members of the academy, although his presence is usually tied to his closest group. However, there is a figure within the school whom Dazai respects in a completely different way. Teacher **Sakunosuke Oda** has, over time, become a kind of mentor to him. Oda is one of the few people capable of speaking to Dazai without being swayed by his carefree facade, understanding aspects of his personality that most simply ignore. Dazai feels a deep appreciation for him and often seeks his company even when he doesn't need any advice. Although he would never express it openly, Oda represents one of the most important people in his life. Naturally, there had to be someone capable of driving him crazy. Since **Chūya Nakahara** arrived at **Bungo School**, the two have maintained a rivalry as constant as it is absurd. Arguments arise for any imaginable reason: sports competitions, grades, sarcastic comments, or simply because one decided to provoke the other. The curious thing is that, despite the frequency with which they argue, those who know them know that there is a strange synchrony between them. Neither seems willing to admit it, but they share an almost instinctive ability to understand how the other will react. Behind his carefree smile and constant jokes, Dazai is a person difficult to decipher. He rarely allows anyone to see what he really thinks or feels, preferring to hide any emotion behind a witty remark or an out-of-place joke. For many, that attitude makes him a complete enigma. Perhaps that is why no one can claim to truly know Osamu Dazai. And that is probably exactly what he intends.

# Paul Verlaine Si hubiera que describir a **Paul Verlaine** con una sola palabra, probablemente sería **elegancia**. Siempre impecablemente vestido, de modales refinados y una serenidad difícil de alterar, transmite una presencia que impone respeto incluso antes de pronunciar una palabra. Sin embargo, quienes lo conocen saben que detrás de esa apariencia fría y distante se esconde una persona profundamente protectora y sorprendentemente sensible con aquellos a quienes ama. Actualmente cursa sus estudios universitarios mientras compagina su vida académica con un trabajo de medio tiempo para poder mantener tanto su hogar como a su hermano menor, **Chūya Nakahara**. Aunque la carga de responsabilidades es considerable para alguien de su edad, jamás se ha permitido descuidar ninguna de ellas. Su disciplina, inteligencia y dedicación lo han convertido en uno de los alumnos más destacados de su facultad, ganándose el reconocimiento de profesores y compañeros por igual. Su mayor prioridad, sin embargo, nunca ha sido su futuro profesional. Es Chūya. Desde que ambos quedaron prácticamente solos, Verlaine asumió el papel de hermano mayor con una intensidad que muchas veces roza la sobreprotección. Constantemente se preocupa por su bienestar, intenta anticiparse a cualquier problema que pueda surgir y procura que nunca le falte nada. Aunque sus constantes advertencias y su necesidad de controlar cada aspecto de la vida de Chūya suelen terminar en discusiones, Verlaine jamás ha dejado de verlo como la persona más importante de su vida. Para él, proteger a su hermano no es una obligación, sino una promesa que se hizo a sí mismo hace mucho tiempo. Precisamente por ese deseo de mantenerlo a salvo, nunca terminó de confiar del todo en **Las Banderas**. Aunque reconoce que son buenos chicos y sabe cuánto significan para Chūya, siempre creyó que la naturaleza impulsiva del grupo terminaría arrastrándolo a situaciones peligrosas o irresponsables. Movido por esa preocupación, utilizó discretamente algunos de sus contactos para favorecer el traslado de Chūya a **Bungo School**, convencido de que allí tendría mejores oportunidades tanto académicas como personales. Fue una decisión tomada únicamente pensando en el bienestar de su hermano. Sin embargo... Es un secreto que jamás pretende revelar. Sabe perfectamente que, si Chūya descubriera que él intervino en aquella decisión, probablemente interpretaría el gesto como una traición. Esa posibilidad lo atormenta más de lo que está dispuesto a admitir, por lo que ha decidido cargar con ese peso en silencio, esperando que algún día su hermano pueda comprender las razones detrás de sus actos. Gracias a su excelente desempeño universitario y a su reputación dentro del ámbito académico, Verlaine ha construido una extensa red de contactos. Entre ellos se encuentran figuras reconocidas como **Ōgai Mori** y **Kōyō Ozaki**, con quienes mantiene una relación de mutuo respeto. Fue precisamente gracias a ese entorno donde terminó conociendo a quien cambiaría por completo su vida. **Arthur Rimbaud.** Ambos se conocieron durante el último año universitario de Rimbaud. Lo que comenzó como una relación basada en intereses académicos terminó convirtiéndose, poco a poco, en una de las relaciones más sólidas que ambos han experimentado. Verlaine encuentra en Rimbaud una calma que pocas personas son capaces de ofrecerle. A su lado baja la guardia con una naturalidad que sorprende incluso a quienes lo conocen desde hace años. Son una pareja estable, afectuosa y profundamente enamorada. No es extraño verlos compartiendo pequeños gestos de cariño, caminando juntos después del trabajo o intercambiando discretas muestras de afecto cuando creen que nadie está mirando. Rimbaud es también una de las pocas personas capaces de mediar cuando las inevitables discusiones entre los hermanos Nakahara alcanzan su punto máximo. A diferencia de la imagen distante que proyecta, Verlaine posee un afecto inmenso por las pocas personas que forman parte de su círculo cercano. Simplemente... no sabe expresarlo con facilidad. Es un hombre reservado, introvertido y extremadamente selectivo con las personas en quienes deposita su confianza. No disfruta especialmente de los grandes grupos ni de las reuniones sociales, prefiriendo la tranquilidad de un café, una conversación en voz baja o una tarde en casa antes que cualquier evento concurrido. Más de un conocido bromea diciendo que "odia a la humanidad", y aunque él jamás lo confirmaría, tampoco hace demasiado por desmentirlo. De origen francés, aún conserva un ligero acento al hablar japonés. En ocasiones, especialmente cuando está cansado, molesto o distraído, mezcla palabras en francés o tarda unos segundos en encontrar la expresión correcta, algo que Rimbaud suele encontrar encantador y que Chūya aprovecha para molestarlo siempre que tiene la oportunidad. Aunque transmite una imagen de absoluta seguridad, Verlaine carga con una constante sensación de responsabilidad. Siempre siente que debe ser más fuerte, trabajar más duro y proteger mejor a quienes ama. Esa necesidad de hacerlo todo por su cuenta le dificulta pedir ayuda, incluso cuando claramente la necesita. Si hay algo que define a Paul Verlaine por encima de cualquier otra cualidad, no es su inteligencia, ni su elegancia, ni su impecable reputación. Es su inquebrantable devoción hacia las dos personas que considera su hogar. Chūya Nakahara y Arthur Rimbaud. Por ellos sería capaz de renunciar a cualquier cosa, incluso si eso significa cargar con el peso de decisiones que nadie más llegará a comprender.

# Arthur Rimbaud Within the halls of **Bungo School**, few teachers are as difficult to describe as **Arthur Rimbaud**. To some students, he is an eccentric man; to others, a walking mystery. Always impeccably dressed in long coats, scarves, or earmuffs, even when the weather doesn't seem to justify it, he is often heard complaining about the cold regardless of the season. Many students joke that Rimbaud is simply incapable of feeling warm. Paradoxically, though he constantly claims to be freezing, he rarely falls ill. He never misses his classes and maintains near-perfect punctuality, making him one of the most reliable teachers in the institution. Rimbaud teaches with a unique blend of discipline and patience. He is a demanding professor who expects commitment from his students and does not tolerate irresponsibility or disrespect in class. However, that severity never stems from cruelty. He is always willing to re-explain a topic, answer questions, or stay after class to help those who truly wish to learn. For this reason, his reputation among students is curious: many fear him during exams, but few would call him a bad teacher. On the contrary, he is considered one of the most reliable and competent educators at **Bungo School**. After school hours, it’s not unusual to hear a melody drifting from the music room. Those curious enough to approach often find Rimbaud sitting at the piano, completely focused as his hands wander over the keys. Few students dare to interrupt these moments, as even those who don't know him well perceive a tranquility there that is hard to find anywhere else in the school. His aversion to the cold is legendary. During breaks, he usually settles onto the same bench in the courtyard—the one where the sun's rays linger longest. He is often seen silently enjoying the warmth while holding a cup of coffee or tea. Many students now know that spot as "Professor Rimbaud’s corner." Among the faculty, he maintains a particularly close friendship with **Ōgai Mori**, who runs the school infirmary. Their relationship is peculiar to outside observers. Mori enjoys teasing him with ironic comments and absurd talk, while Rimbaud responds with a mix of resignation and patience, making it clear he is more than used to his quirks. Despite this, they share a trust built over years and often spend their breaks chatting in the infirmary or having coffee together. Since **Chūya Nakahara** arrived at **Bungo School**, Rimbaud has taken a special interest in his adjustment to the academy. Although he tries to maintain a professional demeanor in class, it is evident that he feels a great deal of affection for him. After all, Chūya is not just one of his students: he is also the younger brother of **Paul Verlaine**, his partner. Far from trying to overstep, Rimbaud strives to be a support figure for Chūya, especially when inevitable arguments with Verlaine complicate matters. He is always ready to listen, offer advice, or simply remind him that he doesn't have to shoulder all his problems alone. Outside of school, Rimbaud leads a quiet life with Verlaine. While Verlaine tends to take on an excessive amount of responsibility, Rimbaud provides the balance needed to keep him from burning out. He is the one who reminds him to rest, eat on time, and allow himself to let his guard down occasionally. It is not rare to see him holding Verlaine’s hand after a particularly heavy day or convincing him to step away from work for a walk. Their relationship is built on deep mutual trust. They don't need grand gestures to express how much they care; small actions, shared silences, and knowing looks often say more than any declaration. Although he often seems reserved, Rimbaud is an extraordinarily kind person to those who manage to get close to him. He prefers listening to speaking and rarely raises his voice outside the classroom. He is selective with his inner circle, but deeply loyal once he places his trust in someone. Many students agree on one thing: approaching Professor Rimbaud for the first time can be intimidating. Finding out that he is one of the most patient and understanding people in the whole school is usually the real surprise.

# Sakunosuke Oda Within **Bungo School**, few teachers inspire as much respect and affection as **Sakunosuke Oda**. Although he is one of the youngest faculty members—surpassed only by Arthur Rimbaud—he possesses a maturity and serenity that lead even the most experienced teachers to seek his counsel. At first glance, he may seem like a difficult man to get to know. He speaks little, maintains a calm expression, and rarely raises his voice. His presence radiates an unshakable stillness, as if very little could rattle him. However, attending one of his classes reveals why so many students consider him one of the best teachers in the school. When he teaches, that apparent quietness vanishes. He explains every topic with sincere passion, ensuring all his students understand before moving on. He never ridicules a question, never loses patience with those who need more time, and always finds new ways to explain things. His goal is not to shape perfect students, but individuals capable of growing on their own. It is precisely this dedication that has made him one of the most beloved teachers at **Bungo School**. Though his way of showing affection is subtle, Oda has a distinct charisma. He requires no grand speeches or exaggerated gestures to earn trust; a quiet conversation or a simple word of encouragement is often enough for students to feel they can turn to him when things go wrong. Outside the classroom, he leads a surprisingly simple life. He has a massive weakness for extremely spicy food, to the point that many teachers no longer blink when they see him adding hot sauce to almost anything. Occasionally, when the school day ends and he is sure no student is watching, he slips away to smoke a cigarette—a small habit he tries to keep hidden, convinced that a teacher must always set an example. Among the staff, he shares a peculiar relationship with **Ōgai Mori**, the school nurse. They have known each other for years, but rarely stay together for more than a few minutes before one decides to leave. No one knows exactly what happened between them, though rumors suggest they are simply unable to agree on anything. Neither bothers to confirm or deny these stories. Outside of school, there is a side to Oda that few know. He is the adoptive father of **six orphans**, who are the center of his life. Every effort he pours into his work has a single purpose: to provide them with a warm home and a future full of opportunities. He speaks little of them, but mentioning any of the children instantly softens his expression. Those who have seen him with them find it hard to believe he is the same serious teacher who enforces silence in a room full of teenagers. His ability to deal with children has also made him immensely popular with the elementary students at **Bungo School**. It is not uncommon to find him during breaks helping in the younger classrooms, playing in the courtyard, or simply listening to the endless stories the children insist on telling him. To many of them, Mr. Oda is not just a teacher—he is a true hero. However, among the older students, there is a joke that has become impossible to ignore. Many claim that Oda doesn't have six children. He has seven. And the seventh is named **Osamu Dazai**. Though he would never admit it publicly, it is evident that Oda feels a very special affection for him. Ever since Dazai arrived at the school, Oda seems to keep track of every detail: whether he attended class, finished his assignments, slept enough, ate lunch, or managed to get home without trouble. He often searches the entire school when Dazai disappears during class, a task the other teachers consider part of their daily routine. Their relationship transcends that of a simple teacher and student. Oda recognizes Dazai's enormous potential but also perceives a loneliness few notice. Without trying to change who he is, he strives to be a constant, reliable presence—someone Dazai can always turn to when it counts. Perhaps that is why many students joke that Oda watches over him exactly as he does the elementary children. And, to everyone's surprise, Dazai never seems to mind.

# Ranpo Edogawa When people first hear that **Ranpo Edogawa** is the smartest student at **Bungo School**, they usually imagine a serious, immaculate young man completely dedicated to his studies. The reality is quite different. Instead, they find a young man of average height, messy hair, a relaxed expression, eyes almost always half-closed, and an absurd amount of sweets tucked into his uniform pockets. It is common to see him walking down the halls with a pack of candy in his hand, resting during class, or even complaining that "thinking makes you hungry." Most people's first impression is exactly the same: *"Is he really the smartest student in the whole school?"* That is until they see him solve a problem. Ranpo possesses an ability for observation and deduction that far surpasses any other student at the academy. To him, what others find complicated rarely presents a real challenge. He can reach conclusions in seconds of observation, spot errors no one else notices, or answer questions before the teacher has even finished asking them. Many claim they have never seen him study seriously. And yet, he always gets the best results. His intelligence has become a sort of legend within **Bungo School**, to the point where even teachers occasionally turn to him when they need to solve something particularly complex. Although this could have made him arrogant, Ranpo simply considers it natural. After all, from his perspective, solving problems is as simple as breathing. His personality is as striking as his intelligence. Eccentric, carefree, and completely confident in himself, Ranpo never goes unnoticed. He has a habit of saying exactly what he thinks without worrying too much about tact, which often gets him into quite peculiar situations. Even so, it is hard to be mad at him for long; he possesses a childlike charisma that ends up disarming even the most serious people. Very few students know one of the academy's best-kept secrets. Ranpo is the adopted son of teacher **Yukichi Fukuzawa**. Although both try to keep that information private, those who know them well know that their relationship goes far beyond that of teacher and student. Fukuzawa is probably the only person capable of truly getting Ranpo's attention when he starts to push things too far. In the same way, Ranpo shows absolute trust in him, even if he rarely expresses it in words. If there is anyone Ranpo considers family besides Fukuzawa, that person is **Akiko Yosano**. They have known each other since they were little and have shared practically their entire lives. There is a complicity between them that few manage to understand; they can hold entire conversations with just a few glances or finish a sentence that the other hasn't even started. Ranpo tends to refer to her as his older sister, and Yosano, though she rarely admits it, feels the exact same way. They have been present for each other's most important moments, and neither imagines a future where the other isn't there. Within the academic sphere, there is only one person capable of truly keeping up with him. **Osamu Dazai.** Although Ranpo remains considered the brightest student in school, he recognizes in Dazai someone whose intelligence is worthy of respect. Their conversations often quickly turn into endless debates on logic, strategy, literature, or whatever topic piques their curiosity. From the outside, they seem to be constantly competing, but those who know them know that behind that rivalry exists a mutual admiration that neither would be willing to admit out loud. He has a very different relationship with **Doppo Kunikida**. Kunikida has enormous respect for Ranpo and rarely doubts his conclusions. He puts full trust in his judgment, even when it seems completely absurd to other students. Despite being fully aware of Kunikida's naivety and honesty, Ranpo never takes advantage of it. He appreciates him too much to use his intelligence against him, and although he enjoys playing little pranks on him from time to time, he always makes sure they never go too far. Behind his carefree attitude is an extraordinarily perceptive person. Ranpo usually understands the emotions of those around him before they are even able to name them themselves. However, he rarely intervenes directly. He prefers to give little nudges, apparently casual comments, or subtle hints that allow others to find the answer for themselves. That particular way of helping makes many people fail to understand how much he does for those he cares about. He is a self-proclaimed lover of sweets. Candies, chocolates, cookies, cakes... anything with sugar seems to mysteriously disappear when Ranpo is near. More than once, he has been caught rummaging through the staff room drawers or accepting bribes in the form of treats to help solve minor school mysteries. Although Fukuzawa constantly insists he should moderate himself, Ranpo simply replies, "the brain consumes a lot of energy." To most students, Ranpo Edogawa is an incomprehensible genius. To those fortunate enough to truly know him... He is simply a brilliant boy who never lost the curiosity of a child.
