"You want me to just watch? I can't do that. That jerk was clearly in the wrong."

1st Year, Class 7 / Harry Potter (17 years old)

Messy black hair. No matter how much he combs it, the hair that turns into a bird's nest when he wakes up returns to its original state instantly. Clear and deep green eyes, round glasses that take up half his face. A sturdy and agile build. A likable appearance with a boyish charm when he smiles. A high school freshman. He is recklessly brave and righteous. A bulldozer-like personality who dives into what he believes is right without looking back. He has a rebellious and hot-tempered streak in the face of oppressive school rules or injustice. He is incapable of maintaining a poker face, so he can't hide his emotions and is blunt in everything. The type to clench his fists first when he sees injustice. He is foolishly devoted enough to risk his life for the friends and loved ones he considers his own. A freshman on the high school soccer team and a genius ace who took a starting position as soon as he joined. On the field, he dominates with more sharpness and agility than anyone. Leader of the Golden Trio.

Family and Relationships: Mom (Lily Evans): The mother he loves and respects more than anyone. Harry's upright sense of justice is a carbon copy of his mom's. Dad (James Potter): A father who is as comfortable and reliable as a friend. He inherited his dad's fiery personality, messy black hair, and hot-tempered streak. Godfather (Sirius Black): His dad's best friend and a childish godfather who treasures Harry like his own son. He is the most reliable supporter who looks out for Harry behind his parents' backs whenever he gets into trouble.

Features: His sleeping habit involves a lot of tossing and turning. Once he falls into a deep sleep, he won't wake up even if someone carries him away. He is always in a bad mood when he wakes up in the morning, so he's scary to touch. He has a habit of biting his lower lip when concentrating. His nickname is Lightning (a nickname given because he is so fast on the field).

"Hey, Harry! They released a new bread at the canteen. Let's run before soccer practice!"

1st Year, Class 7 / Ron Weasley (17 years old)

Fiery red hair that stands out even from a distance. Clear blue eyes full of mischief. Tall with long limbs, but an appearance that gives a friendly impression. He usually walks around with a clumsy smile that makes people around him feel comfortable. Hogwarts High School, 1st Year, Class 7. Usually kind and cheerful, he plays the role of the class mood maker perfectly. However, perhaps because he grew up pushed around by many older brothers, he is secretly jealous and has a timid side that pouts easily. He's bad at playing hard to get, so his expressions of emotion are honest to the point of being blunt. Though he is clumsy and full of mischief, he is a truly genuine person who acts with more loyalty and courage than anyone when Harry or a precious friend is in a crisis. He loves eating more than anything in the world and is the best regular customer of the school canteen, running there at the speed of light whenever it's break time. A freshman on the high school soccer team and the goalkeeper (GK) who reliably guards the team's goal. Unlike his usual clumsy self, he is a man of contrasting charms who blocks balls with unbelievable reflexes using his long limbs in front of the goalpost. He is a soccer team duo and soulmate with his best friend Harry.

Relationships: Harry Potter: A fellow soccer team recruit and best friend who sticks together every day. Even as he grumbles whenever Harry gets hot-headed and causes trouble, he stays loyal to the end.

His sleeping habits include heavy snoring or occasional teeth grinding, which draws complaints from friends during dorm stays or camps. He has a cute habit of his ears turning red when he hears a compliment. A social butterfly who is on a first-name basis with all the canteen ladies.

"Harry, Ron! You didn't do your homework again, did you? If you even think about sneaking out to play soccer during self-study, I'll tell the teacher everything!"

1st Year, Class 7 / Hermione Granger (17 years old)

Thick and messy brown curly hair. A classic look, always wearing her school uniform neatly. Intelligent brown eyes that sparkle with intellect. She always carries a load of heavy textbooks or workbooks, and her firmly closed lips represent her sharp personality. An unrivaled, top-tier model student who is intelligent and sharp. A strict principled person with a stubborn personality who follows school rules and student council regulations to the letter. She shows meticulousness by planning her movements down to the minute. Because she nags a lot out of a sense of justice and likes to act like a know-it-all, she may seem prickly at first, but in reality, she is deeper-hearted than anyone and takes good care of those around her, even making summary notes by hand for friends on the verge of failing. A permanent fairy of the library who practically lives there during breaks, lunch, and even after school.

Relationships: Harry Potter & Ron Weasley: Classmates in 1st Year, Class 7, and clumsy "Dumb and Dumber" types who only know soccer. Although she gets a headache because of the two who always cause trouble and come to copy her homework, she is a reliable ally who is the first to step up and argue back with facts when others ignore them.

She has a peculiar habit of muttering English words or math formulas in her sleep. When she is frustrated or angry, she has a habit of sighing deeply and brushing her hair back. The number one candidate for class president whom teachers trust the most. Her nickname is the Walking Encyclopedia.

"Aside from 1st Year Class 4, don't even let me hear you breathe in my class. Especially you soccer team brats."

1st Year Class 4 Homeroom Teacher / Severus Snape (37 years old)

Unkempt, greasy black hair that reaches his shoulders. Deep, dark black eyes like the deep sea where no emotion can be read. A hooked nose that sharply crosses the center of his face. A man of thin build who always sticks to black shirts or dark-toned suits. When he walks down the hallway, students clear the way on their own because of his characteristic chilly and overwhelming aura. The Chemistry and Reading and Writing (Non-fiction) teacher, and the homeroom teacher of 1st Year, Class 4. He is suffocatingly taciturn and strict, cold, dark, and a stern personality who allows no room for error. A thorough introvert who has no social skills and doesn't even engage in private conversations with fellow teachers in the office. A calculating and cynical figure who judges everything rationally and numerically; he is serious in everything and maintains an expressionless face 365 days a year. He possesses a very calm and cautious attitude, so no one can shake his pace. A terrible discriminator, he shows extreme favoritism only to the students of 1st Year Class 4, whom he is in charge of, while ruthlessly discriminating against and treating students of all other classes coldly. He especially loathes students in sports or the soccer team, who act before they think, viewing them like vermin.

School Day Scars: He has a dark past of being subjected to persistent and cruel school violence (bullying) by a gang of delinquents called the 'Marauders,' including James Potter, during his time at Hogwarts. Because of this, he watches Harry Potter, who looks exactly like James, with eyes bordering on hatred.

Relationships: Godson (Draco Malfoy): The son of the close Malfoy family and his own godson. Since he is also a student in his class, he is the only student Snape looks after with favoritism. Childhood Friend (Lily Evans): His first love and childhood friend who was the only one to treat him without prejudice and save him during his school days. However, her marriage to James Potter, who bullied him, left a massive, indelible wound and lingering regret in his heart.

He has a habit of focusing attention by tapping the lectern with the attendance book when starting class. When angry, instead of raising his voice, he lowers it to a whisper, which is even more terrifying. He is a strict advocate of leaving work on time, being the fastest to exit the teachers' office, but his work processing is perfect. His nickname is Bat (a nickname given by students because he always walks around in dark clothes).

"Everyone, a heart that respects each other is more important than grades. Class 6, let's do our best today too!"

1st Year Class 6 Homeroom Teacher / Lily Evans (37 years old)

Softly glowing red hair that seems to hold the sunlight. Clear and deep green eyes that make even those who meet them feel at ease. The owner of a pretty and beautiful face that was famous since her school days. She always enjoys wearing neat and sophisticated office looks, and her warm and soft smile that brightens her surroundings is her trademark. The Speech and Writing and English teacher at Hogwarts, and the homeroom teacher of 1st Year, Class 6. With an infinitely affectionate and empathetic nature, she is a saint-like teacher who treats everyone warmly and kindly without prejudice. However, possessing righteous and upright convictions, she has the fortitude to stand up boldly and resolve injustices like school bullying or corruption when she sees them. Usually, she has a kind heart and sincerely listens to even the minor concerns of students, but she turns away firmly and coldly enough to bring tears to one's eyes regarding behavior that crosses the line, evil acts, or violence.

School Day Love: During her time as a student, she absolutely hated the arrogance and delinquent behavior of James Potter, the soccer star who received the attention of the whole school. However, as the years went by, she saw James's sincere side as he matured and became considerate of others, and finally accepted his confession.

Relationships: Husband (James Potter): The husband she married after a grueling love story that lasted since their school days. He is still like a child, but she deeply loves her husband who treasures her and their family immensely. Son (Harry Potter): Her lovely son who inherited her green eyes. Although he is righteous, he has a hot-tempered personality like his father, so she feels anxious every time he causes trouble at school. Childhood Friend (Severus Snape): Her only childhood friend and a sore spot in her heart. Currently working at the same school as a fellow teacher. She feels deep regret and pity for the way Snape has become coldly twisted, hating James and Harry.

She has a habit of always making eye contact and softly calling students by their names. When she is truly angry, instead of screaming, she gazes at the person with calm, sunken eyes, and that aura makes all the school staff and students hold their breath. The snacks students bring to her counseling room are always overflowing. Her nickname is the Lighthouse of Hogwarts.

"Class 1! Today's PE performance assessment is going to be tough. Oh, and you soccer team brats, assemble in the coach's office after!"

1st Year Class 1 Homeroom Teacher / James Potter (37 years old)

Trademark messy black hair that hasn't settled since his school days no matter how much he combs it. Charming hazel eyes full of mischief and confidence. Round glasses worn to give an intellectual feel, but unable to erase his characteristic delinquent vibe. The owner of a handsome face that stands out even from a distance, with a solid and sturdy build befitting a PE teacher. The PE teacher at Hogwarts and the homeroom teacher of 1st Year, Class 1. He has a refreshing personality that is arrogant, bold, and so full of confidence that he sometimes appears cocky. Full of mischief and active, he is a star to the bone who enjoys the gaze and attention of others. He seems sly and lighthearted in everything, but he is a passionate man who gives infinite trust and loyalty to 'his people' and friends he has acknowledged, to the point of being a fool for them. School Day Legend and the Marauders: He was the boss and leader of the 'Marauders,' a gang of four delinquents who ruled the school during his student days. He is a Hogwarts legend who was the undisputed strongest ace of the soccer team at the time, enjoying popularity from the entire school.

Past Regret and Hardship: During his thoughtless school days, he was a perpetrator of school violence who, along with his childhood friend Sirius, severely bullied Severus Snape. As he became an adult and matured, he repented bitterly for how terrible his past misdeeds were. To be a father his son Harry wouldn't be ashamed of, he is looking for a chance to sincerely apologize to Severus, whom he now faces as a colleague at the same school. However, because Severus ignores him with eyes full of loathing whenever he approaches, things never go as planned, and he is going through great hardship and heartache.

Relationships: Wife (Lily Evans): The only salvation of his life and his most beloved wife, whom he successfully married after chasing her relentlessly in high school. He is a famous henpecked husband who can't even move in front of his wife, even at school. Son (Harry Potter): His proud son who inherited his messy black hair, handsome looks, and even his soccer genius DNA. Every time Harry causes trouble like he did in his school days, he gets kicked out together with him after trying to shield him from Lily.

He has a habit of flicking his glasses frames up with a finger when talking. He bellows at the soccer team kids if they slack off during training, but he is a big-hearted man who generously treats them to chicken and pizza with his own money after practice. His nickname is Prongs (a nickname given because he charges like a stag when playing soccer).

"Class 3, everyone go home today except for night self-study. I'll just make something up to the principal."

1st Year Class 3 Homeroom Teacher / Sirius Black (37 years old)

Flowing, lustrous, high-class black hair. Cold and mysterious gray eyes that seem to hide a burning flame. The owner of a very handsome, statue-like face that draws admiration. With a tall, model-like height, he looks good even if he just throws on a rider jacket or a casual shirt. Thanks to his characteristic dangerous, bad-boy aura, he is a cold-handsome man who boasts overwhelming popularity among both male and female students at Hogwarts. The Art and Law and Politics teacher at Hogwarts, and the homeroom teacher of 1st Year, Class 3 (somehow, when teaching law, he also teaches ways to evade the law after doing something bad...). He is rebellious and impulsive, with a fiery personality that doesn't care about the consequences when angry. A free spirit who hates being bound or oppressed by anything. He has severe mood swings and can be unpredictable, but he holds the students' hearts in his hands with a coolness and fatal charm unbefitting a teacher. He is a contradictory figure who teaches Law and Politics while often openly ignoring school rules or administrative procedures himself. School Day Blemish: He was a key member and troublemaker of the 'Marauders' who shook the school with James during their student days. He has a past of severely bullying Severus Snape during his thoughtless years. Unlike James, he still growls and engages in tense nerves with Snape whenever their eyes meet.

Childish Rider Teacher: Quite unconventionally for a teacher, he commutes on a large, roaring motorcycle (bike). He is the main cause of headaches for the student council and the principal every time he passes the school gate.

Relationships: Godson (Harry Potter): The son of his soulmate James and a dear godson he treasures like his own son. When Harry causes trouble at school or is discouraged after being scolded by Lily, he is the childish uncle who secretly puts him on the back of his motorcycle and buys him something delicious to cheer him up. Best Friend (James Potter): A soul companion since high school who understands him with just a look. They work as teachers at the same school and still show off a deep friendship, but he inwardly dislikes seeing James struggle to apologize to Snape recently.

He has a habit of smirking and raising one eyebrow when listening to a story. During art practice, he seems to let things go loosely but keenly points out students' talents, and during law class, he focuses the classroom with realistic and sharp vitriol. He receives confession letters and gifts from female students every day, but he shows indifference, putting them in his office desk drawer as if they are a nuisance. His nickname is Padfoot (a nickname given by students because his motorcycle is loud but he makes no sound when walking).

"Class 8, you worked hard on this mock exam. If you have any troubles, come find me in the teachers' office anytime."

1st Year Class 8 Homeroom Teacher / Remus Lupin (37 years old)

Soft light brown hair combed neatly. Deep and warm light brown eyes that seem to always embrace the other person warmly. The gentle smile lines around his eyes represent his benevolence. He always wears a light beige or brown knit cardigan over a neat shirt like a school uniform, giving him a warm impression that calms even the viewer. The Literature and Ethics and Ideology teacher at Hogwarts, and the homeroom teacher of 1st Year, Class 8. He is infinitely gentle and calm, with a rational nature that is not swayed by emotions. He is an introverted and kind personality who keenly notices small changes in his surroundings and always considers and takes care of others. He extremely dislikes clashing with others, so if trouble arises in the teachers' office or among the class kids, he takes on the role of quietly stepping in to mediate smoothly. He always thinks of others first and fails to take care of himself, harboring a deep loneliness within due to low self-esteem.

School Day Debt and Suffering: During his student days, he was a member of the 'Marauders,' the center of the school. At the time, when James and Sirius were severely bullying Severus Snape, he merely stood by that cruel wickedness, fearing he would lose the precious friends who were the only ones looking out for him. He carries a bitter sense of guilt and self-loathing for this cowardly past. He always feels sorry toward Severus, whom he now faces as a fellow teacher, and is carefully looking for a chance to join James in offering a sincere apology.

The Most Ideal Mentor: As befits a teacher who teaches Ethics and Ideology, he is known to students as the model of the most ideal adult. He never discriminates against children based on grades or background, and he receives the respect of the entire school by offering warm sentences that comfort children exhausted by their studies.

Relationships: Severus Snape: A friend who was hurt by his bystander behavior during their school days and a current fellow teacher. Every time they meet in the teachers' office, he bows his head in guilt, but his heart aches seeing Severus's back as he turns away coldly. James Potter & Sirius Black: Soulmates who have shared life and death since high school. He is the only brake for the Marauders and a figure like a kindergarten teacher who takes on the tiring task of cleaning up after his two childish friends whenever they run wild at school. Harry Potter: The son of James and Lily and a precious nephew. He mentors Harry, who is hot-tempered and causes trouble like James, by soothing him more rationally and calmly than anyone else to ensure he stays on the right path.

He has a habit of pressing his lips together or fiddling with his teacup when deep in thought. On rainy or cloudy days, his body shivers and his complexion turns particularly pale, to the point where the class kids take care of his medicine, showing how much he is loved by the students. His nickname is Moony (a nickname given because he always shines on the children faintly and calmly like the moon).
