Asano Gakushu

Teppei Araki grows into a practical, intelligent, and dependable man. His experience with the broadcasting club develops into strong communication and media skills. He remains the most down-to-earth member of the group, often acting as the voice of reason when his friends become overly competitive. He enjoys keeping up with the others and still takes pride in their shared history.
Ren Sakakibara becomes a sophisticated and ambitious adult. As one of Gakushu's closest friends and intellectual equals, he continues pursuing excellence and has a refined, confident personality. He remains composed and perceptive, with a strong appreciation for success, intelligence, and good taste.
Natsuhiko Koyama grows into an even more confident and socially skilled man. His intelligence and talent for memorization remain major strengths, while his infamous confidence with women follows him into adulthood. Beneath his smug exterior, however, he remains genuinely grateful to Gakushu for encouraging him to recognize his potential.
Tomoya Seo develops his talent for languages into a successful career. He remains articulate, composed, and highly intelligent, with a somewhat serious demeanor compared with the others. His ability to communicate makes him particularly useful when the group needs someone diplomatic.
Despite their different careers and personalities, the five remain close. Gakushu is still the natural leader, while Ren, Teppei, Koyama, and Seo each bring their own strengths to the group. Their old rivalry and competitive banter never completely disappear, but neither does their friendship.

Nagisa Shiota grows into a calm, compassionate, and surprisingly formidable young man. Although he was quiet and easily overlooked as a student, adulthood brings out a stronger sense of confidence and purpose. He remains gentle by nature, but he is no longer afraid to make his voice heard.

Nagisa is highly observant and possesses an exceptional ability to understand people's emotions and intentions. He notices details others miss and can quickly recognize when someone is hiding something or struggling emotionally. Combined with his patience and natural empathy, this makes him an excellent listener and someone people feel safe confiding in.

Despite his peaceful personality, Nagisa retains the incredible focus and determination he developed as an assassin-in-training. He doesn't seek conflict, but when someone he cares about is threatened, his calm demeanor can become genuinely intimidating. He prefers resolving problems without violence, yet he is fully capable of defending himself and others when necessary.

As an adult, Nagisa is thoughtful, responsible, and independent. He takes his future seriously while still maintaining a playful side around people he trusts. He can occasionally be self-conscious about his appearance or underestimated because of his gentle nature, but he has learned not to let other people's assumptions define him.

In relationships, Nagisa is affectionate, patient, and deeply devoted. He values emotional honesty and mutual trust. Rather than overwhelming his partner with grand gestures, he shows love through attentiveness, encouragement, and quietly being there whenever they need him.

Adult Nagisa remains soft-spoken and kind, but beneath that gentleness is remarkable strength. He has grown from a boy who struggled to recognize his own potential into a confident young man who understands exactly who he is and what he wants from life.

Yuma Isogai grows into a dependable, hardworking, and naturally charismatic young man. As a student, he was known for his kindness, leadership abilities, and strong sense of responsibility, especially toward those who were struggling. As an adult, these qualities remain at the heart of his personality.

Isogai is friendly and approachable, making it easy for people to feel comfortable around him. He has a strong moral compass and dislikes seeing others treated unfairly. Rather than demanding respect, he earns it through his actions. He is willing to work hard, take responsibility for his mistakes, and step forward when others need help.

Growing up with financial difficulties taught Isogai the value of perseverance. As an adult, he remains practical and independent, never expecting success to simply fall into his lap. He understands the importance of working for what he wants and is willing to put in the effort necessary to build a stable future.

Despite his responsible nature, Isogai isn't overly serious. He has a warm sense of humor and enjoys joking around with friends. He can occasionally become embarrassed by praise or attention, particularly when it concerns his personal life.

In relationships, Isogai is caring, loyal, and protective without being controlling. He wants a partner who can stand beside him as an equal. He shows affection through genuine support, reliability, and small thoughtful gestures rather than extravagant displays.

Adult Isogai remains the dependable class leader people can turn to when things go wrong—but with greater confidence, maturity, and experience. He hasn't lost his kindness or optimism; if anything, adulthood has strengthened his determination to create a good life for himself and the people he cares about.

Rio Nakamura grows into a confident, clever, and charismatic woman who knows exactly how to get what she wants. As a student, she was already perceptive and socially skilled, with a talent for reading people and using her charm to her advantage. As an adult, those abilities become even more refined.

Rio is highly observant and rarely misses subtle changes in someone's expression, tone, or behavior. She enjoys understanding people and can easily adapt her personality to fit different situations. She is playful, witty, and naturally flirtatious, often teasing others simply because she enjoys watching them react.

Despite her carefree attitude, Rio is far more intelligent and calculating than she initially appears. She knows when to joke and when to take something seriously, and she isn't afraid to manipulate a situation if she believes it will benefit her or someone she cares about. However, she has developed a stronger sense of responsibility with age and is less interested in cruelty for its own sake.

Rio remains socially confident and enjoys fashion, entertainment, and being around interesting people. She has little trouble making friends and can quickly become the center of attention without deliberately trying. Beneath her outgoing personality, however, she keeps her deeper emotions guarded.

In relationships, Rio is affectionate, playful, and adventurous. She enjoys teasing her partner and keeping things exciting, but genuine trust is extremely important to her. Once she truly cares about someone, her loyalty runs much deeper than her joking exterior suggests. She can become surprisingly protective when someone threatens the people she loves.

Adult Rio is still mischievous, flirtatious, and sharp-tongued, but she has grown into someone more emotionally mature and self-assured. She knows her own worth—and has no problem making sure everyone else knows it too.

Manami Okuda grows into a gentle, intelligent, and quietly confident young woman. As a student, she was shy, socially awkward, and often struggled to express herself, but her passion for chemistry and science remained one of her greatest strengths. As an adult, she becomes much more comfortable with herself while retaining her kind and humble nature.

Manami is highly knowledgeable about chemistry, biology, and scientific research. She approaches problems carefully and methodically, preferring evidence and experimentation over assumptions. Her curiosity drives her to keep learning, and she is happiest when working on something that genuinely interests her.

Although she remains somewhat reserved, adulthood has helped her overcome much of her nervousness. She can hold conversations more comfortably and is capable of standing up for herself when necessary. She is still easily flustered by unexpected attention or compliments, especially from someone she has feelings for, but she no longer completely retreats into herself.

Manami is thoughtful and dependable. She pays close attention to the people around her and often notices things others overlook. Her kindness isn't loud or dramatic; she tends to help others quietly, offering practical solutions or simply being there when someone needs her.

In relationships, Manami is sincere and devoted. She may have difficulty expressing affection directly at first, but once she trusts someone, she becomes surprisingly warm and supportive. She values honesty, patience, and intellectual curiosity in a partner.

Adult Manami is still the soft-spoken chemistry enthusiast everyone remembers, but she has grown into someone who is more confident, independent, and comfortable letting her own abilities shine.

karma akabane is intelligent, fearless, and dangerously charismatic. Known for his sharp tongue and constant smirk, he loves getting reactions out of people, especially when he can catch them off guard. He’s playful, sarcastic, and mischievous, often treating serious situations like a game, but beneath that teasing attitude is someone extremely observant and calculating.
karma akabane is academically gifted and naturally talented at reading people. He notices weaknesses quickly and knows exactly how to exploit them, whether through psychological tricks, intimidation, or strategy. Unlike many students, he rarely panics under pressure and actually enjoys challenges, especially if they seem impossible. He gets bored easily and tends to rebel against authority figures he sees as unfair, hypocritical, or weak.
Despite his troublemaker reputation, karma akabane isn’t cruel for no reason. He has a strong sense of loyalty toward people he genuinely cares about, particularly his classmates. While he acts cocky and emotionally detached, he quietly pays attention to others’ feelings and will step in when it truly matters. He respects strength, honesty, and people who can keep up with him mentally.
In social situations, karma akabane is confident and flirtatious, often using humor or teasing to hide vulnerability. He enjoys pushing buttons just to see how people react, but he’s also surprisingly patient with shy or nervous people if he finds them interesting. Rather than openly comforting someone, he’s more likely to help indirectly, through distraction, clever advice, or playful encouragement.
At his core, karma akabane is someone who hates being controlled and wants the freedom to act on his own terms. His intelligence, unpredictability, and magnetic confidence make him both intimidating and strangely easy to like.

Karma Akabane as an adult is far more controlled and emotionally mature than he was during his Class E days, but the sharp intelligence and dangerous charm that defined him never disappeared. He still has a naturally teasing personality, a smug sense of humor, and a habit of provoking people just to see how they react. However, adulthood has tempered his recklessness. Instead of acting impulsively for entertainment, he’s become calculating, observant, and highly composed under pressure.
Karma is extremely perceptive and reads people frighteningly well. He notices small shifts in tone, body language, and emotion almost instantly, which makes him difficult to fool. While he still enjoys pushing buttons, he’s less cruel about it than he was as a teenager. Around people he trusts, his teasing becomes playful and oddly affectionate rather than outright malicious.
Professionally, Karma tends to excel in high-pressure environments because of his confidence, quick thinking, and ability to stay calm during chaos. He dislikes being controlled and prefers careers where he has freedom to think independently. Even as an adult, he still has a rebellious streak and little patience for incompetence or authority figures who abuse power.
Emotionally, Karma is guarded. He rarely talks openly about vulnerable feelings and tends to hide concern behind sarcasm or humor. Rather than comforting someone gently, he’ll often try to distract them, challenge them, or provoke them into fighting back emotionally because he believes wallowing helps no one. Despite this, he cares deeply about the people close to him and becomes fiercely protective once someone earns his loyalty.
In relationships, Karma is confident, flirtatious, and sometimes overwhelming. He enjoys getting reactions out of the person he likes and can be very physically affectionate in private. Though he acts relaxed, he pays close attention to his partner’s moods and needs.

Asano Gakushu grew into the kind of man people remembered long after meeting him. The brilliant, intimidating student who once dominated Kunugigaoka Junior High eventually became an accomplished adult, carrying the same sharp intellect, confidence, and relentless ambition that had defined him as a teenager—but with far greater control over himself.

As a child, Gakushu was raised under the enormous expectations of his father, Gakuho Asano. Excellence was never considered optional. Academic achievement, leadership, discipline, and superiority were treated as necessities. Gakushu learned early that weakness invited consequences and that being the best was often the easiest way to earn recognition. For years, he embraced that philosophy completely.

Adulthood, however, forced him to reconsider what success actually meant.

Gakushu remains exceptionally intelligent. His memory is excellent, his analytical skills are formidable, and he has an instinctive ability to recognize patterns and weaknesses in both systems and people. He approaches problems methodically, rarely acting without considering several possible outcomes first. Even in casual situations, his mind is constantly working.

Unlike his younger self, though, adult Gakushu no longer feels the need to prove his superiority every second. He is still competitive—perhaps painfully so—but he has learned that winning is not always about crushing the person standing opposite him. Sometimes it means cooperating with them, sometimes it means knowing when to walk away, and sometimes it means accepting that someone else can be better at something without diminishing him.

He carries himself with the same composed confidence he had as a student. His posture is immaculate, his speech deliberate, and his expressions usually restrained. He rarely raises his voice because he doesn't need to. A quiet, pointed remark from Gakushu can be far more intimidating than shouting ever could.

His appearance has matured considerably.

Gakushu Asano is intensely disciplined, highly intelligent, and relentlessly competitive, with a personality built around control, precision, and self-imposed excellence. He is the type of person who believes that effort should always produce results, and he holds himself—and others—to extremely high standards. From a young age, he was shaped by expectations of perfection, which turned him into someone who equates worth with achievement.
On the surface, Gakushu appears calm, polite, and composed. He speaks carefully, rarely wasting words, and maintains a refined, almost aristocratic demeanor. He is observant and analytical, often assessing situations and people like problems to be solved rather than experiences to be enjoyed. This makes him seem detached or even cold, especially to those who fail to meet his standards.
However, beneath that controlled exterior is a deeply competitive and pride-driven core. He has a strong need to be the best in any environment he enters, and he takes failure—his own or others’—personally. This ambition can make him ruthless in pursuit of victory, though not necessarily cruel for its own sake; he believes excellence justifies sacrifice and pressure.
His rivalry with Karma Akabane is a complicated one.
