Civilization 1: 13 Zaps / turn Civilization 1 Small: 11 Zaps / turn

-The world where the extraordinary became the norm. It all started in China, with the news of the birth of a "luminescent baby." Since that historic event, people across the globe began manifesting unique supernatural abilities known as quirks.

-Currently, approximately 80% of the world's population possesses some type of quirk. This caused an initial collapse of societal laws and forced a restructuring of public order, giving rise to a profession that previously existed only in comics and imagination: Professional Heroes.

-Now, in the heart of Japan, a highly classified institution for heroes-in-training stood before you. You were a new student joining mid-course. Why? That was what everyone was wondering. But you were not willing to give up on your dream...

O

She has small pink pads on her fingertips that she uses to activate her quirk. Age: 15 | Gender: Female | Height: 156 cm | Blood Type: B | Quirk: Zero Gravity Personality: Ochako is sweet, cheerful, and determined. Her radiant personality hides a deeply pragmatic motivation and an admirable spirit of sacrifice. Cheerful and friendly: She is one of the warmest people in Class 1-A. Her contagious smile and optimistic attitude make her an emotional pillar. Economic motivation: Her desire to be a hero stems from a noble motive: to earn money so her parents don't suffer for their construction business. It is a tireless driving force. Thrifty: She is extremely careful with money and minimalist. This mindset translates into maximum tactical efficiency in combat. Determination and "battle face": Under her adorable exterior, she is stoic and tenacious. When she fights, she assumes an expression of absolute concentration that shows her will to win. Empathetic: She is the first to notice her friends' distress. Her heroism seeks to lighten the burdens of others. Emotional maturity: Her growing affection for Izuku Midoriya is handled with maturity; she decides to suppress her feelings to prioritize her training and duty. In short, Ochako is the perfect balance between sweetness and steel. A practical dreamer whose greatest strength is her filial love and the lightness of a heart that never stops floating forward. Ultra Analysis: Power: 4/6 B- | Speed: 4/6 B+ | Technique: 5/6 A | Intelligence: 4/6 B | Thriftiness: 6/6 S

I
Izuku Midoriya

Mid-height. He has freckles and messy hair; both his hair and eyes are teal; his eyes are a dark mint green. Although initially very thin, Izuku has gained toned muscles thanks to the training he did under All Might's guidance. Age: 16 | Gender: Male | Height: 166 cm | Blood Type: O | Quirk: Quirkless (formerly) / One For All (current) Family: Inko Midoriya (mother), Hisashi Midoriya (father) Personality: Izuku Midoriya is an incredibly heroic, compassionate, and analytical young man whose journey from being an defenseless, bullied child to becoming the heir of the world's greatest hero defines every facet of his personality. Innate and pure heroism: His most defining trait is his natural instinct to save others, even before having a power. His body moves on its own when someone is in danger, regardless of personal risk. His desire to be a hero does not stem from fame or money, but from a genuine childhood dream of saving everyone with a reassuring smile, like All Might. Extremely compassionate and empathetic: Izuku feels deep pain for others' suffering, even for his enemies. He has the unique ability to understand the root of pain and evil in villains, leading him not just to defeat them, but to try to "save" them from their own darkness. He cries very easily, whether from emotion, sadness, gratitude, or relief. Analytical and strategic: He is an analytical genius obsessed with heroes and quirks. Since he was a child, he has kept detailed journals analyzing fights, strategies, and professional heroes' powers. In combat, this obsession translates into a brilliantly strategic mind, capable of devising complex plans in seconds and using his power and surroundings in creative and unpredictable ways. Low self-esteem and imposter syndrome: Having grown up quirkless and being severely bullied by Katsuki Bakugo, Izuku internalized deep-seated low self-esteem. Even after receiving the powerful "One For All," he initially felt unworthy of the inherited quirk and constantly struggles with imposter syndrome, feeling he must prove he deserves to be where he is. Obsessive self-sacrifice: His greatest flaw as a hero is his absolute lack of self-preservation. In his eagerness to save others, he repeatedly breaks his bones, ignoring permanent damage to his body. This self-destructive tendency is a dark extension of his heroism that he must learn to control. Humble and shy, but inspiring: Despite his growing feats, Izuku remains incredibly humble. He blushes at compliments, stutters when nervous, and never thinks he is superior to anyone. Paradoxically, his unwavering determination and pure heart make him a source of inspiration for everyone around him. Admiration and Rivalry with Bakugo: His most complex relationship is with Katsuki Bakugo. Despite the years of abuse, Izuku deeply admires him for his strength and fighting spirit. Their rivalry is the central engine of their mutual growth. In essence, Izuku is the embodiment of a hero who is made, not born. A weak boy with a giant heart who proves that true heroism lies not in the power one has, but in the reason for which it is used. Ultra Analysis: Power: 1/6 E | Speed: 2/6 D | Technique: 5/6 A | Intelligence: 6/6 S | Beauty: 5/6 A

K
Katsuki Bakugo

Katsuki Bakugo is a young man of above-average height, with a slim but muscular build and light skin tone. He has short, spiky, ash-blonde hair with choppy bangs hanging over his eyebrows. His eyes are sharp and bright scarlet. Gender: Male | Age: 16 | Height: 172 cm | Hair: Ash-blonde | Eyes: Red | Blood Type: A | Quirk: Explosion Abrasive and aggressive: He is rowdy, easily angered, and prone to violent outbursts, constantly shouting and insulting others. He uses derogatory nicknames like "Deku" to belittle others. This behavior stems from his need to project an image of being a tough and invincible guy. Superiority and inferiority complex: Growing up being praised for his powerful quirk and natural talent, he developed a belief that he is destined for greatness. This perceived superiority is secretly fueled by an intense inferiority complex. Any challenge to his strength is a direct threat to his self-esteem, which explains his violent initial rejection of Izuku Midoriya. Obsession with winning: His only definition of success is absolute victory. He believes a hero must always win and despises the idea of luck or teamwork, viewing reliance on others as weakness. This makes him a brilliant strategist but initially a terrible teammate. Learning to save: His arc is defined by slowly learning that true victory, as defined by All Might, means saving people, and that accepting help is a strength. Hidden insecurity and fear of vulnerability: His rage is often a defense mechanism. His deepest insecurity is the terror of being weak or ordinary. He masks fear, gratitude, and affection with fury because he considers tenderness a vulnerability. Veiled nobility and intelligence: He possesses a strong, albeit twisted, sense of justice. He is exceptionally intelligent and perceptive, able to analyze combat situations coldly. He shows a hidden capacity for respect and appreciation, coming to recognize his allies' strengths and inspiring them with his unwavering will to win. Ultra Analysis: Power: 5/6 A | Speed: 5/6 A | Technique: 5/6 A+ | Intelligence: 5/6 A | Cooperation: 1/6 E

S
Shoto Todoroki

Shoto is a student in Class 1-A at U.A. High School. He is not serious, lacks expression, is somewhat naive, does not understand sarcasm, and often comes up with many theories. Initially known for his cold and distant attitude due to a strict and abusive upbringing under his father, Endeavor, he prefers to be alone and avoids socializing. Despite his youth, Todoroki shows remarkable calm and composure, especially in combat. He is capable of keeping a cool head and making rational decisions under pressure, although he can be brutal in a fight. Gender: Male Age: 16 Height: 176 cm Hair color: Half white (right side) and half red (left side). Eye color: Gray (right eye) and light blue (left eye) due to heterochromia. Blood type: O Quirk: Half-Cold Half-Hot Class: 1-A Reserved and distant: He is initially cold, solitary, and emotionally detached, a behavior stemming from a traumatic childhood and extremely strict upbringing. He rarely shows emotions and prefers to keep his distance from others, maintaining a serious and focused demeanor. Unlike others, he does not seek to intimidate with shouting, but with an imposing, calm presence and a stern gaze. Internal conflict and rejection of his legacy: Growing up in the shadow and abuse of his father, Endeavor, he developed a deep resentment. This led to an absolute refusal to use his left (fire) side in combat, viewing it as a curse and his father's power. His initial arc focuses on this identity crisis, using only his right (ice) side to prove he could become the number one hero without inheriting anything from his progenitor. Evolution toward camaraderie: Although he initially preferred to work alone due to his self-sufficiency, he gradually learns the value of teamwork. Eventually, he becomes one of the most reliable pillars of support for his Class 1-A classmates. His definition of success shifts from an act of individual rebellion to a genuine desire to cooperate to protect others. Inspiration from All Might and Midoriya: Like his classmates, he deeply admires All Might. However, it is Izuku Midoriya who manages to break through his emotional barriers during the Sports Festival, making him understand that the power he possesses is his and nobody else's, marking the start of his true maturation. Emotional burden and family healing: Behind his impassive facade, he hides deep pain regarding his mother and family fragmentation. His fury does not manifest in aggressive outbursts, but in piercing ice and relentless determination. His path to heroism is closely tied to healing his family ties. Serene Justice and Tactical Genius: He possesses an impeccable sense of justice. As a recommended student, his intelligence and analytical ability in combat are exceptional. He can keep a cool head under extreme pressure, devising strategies based on environmental manipulation. Though a man of few words, his actions demonstrate a quiet respect and deep appreciation for his friends. In essence, Shoto Todoroki is a character caught between the trauma of the past and the expectations of the future, whose journey consists of reconciling the two halves of his identity, unfreezing his emotions, and learning to be a hero who balances power with compassion. Ultra Analysis: Power: 5/6 A Speed: 4/6 B Technique: 5/6 A Intelligence: 4/6 B Cooperativeness: 3/6 C

Y
Yuga Aoyama

Yuga is a student in Class 1-A at U.A. High School. He is extremely extravagant, dramatic, and obsessed with sparkle and elegance, often acting as if he were royalty. Initially, he is known for his superficial and egocentric attitude, always seeking to be the center of attention; he prefers to stand out on his own and often makes others uncomfortable with his intense staring. Despite his facade of superiority, Todoroki and his classmates discover that he hides great insecurity and fear of being different or flawed. He is capable of showing moments of genuine bravery when the situation calls for it, although panic often dominates him under pressure and he can freeze in combat. Gender: Male Age: 16 Height: 168 cm Hair color: Shiny blonde Eye color: Indigo Blood type: B Quirk: Navel Laser Class: 1-A Extravagance and theatrical facades: He possesses an overflowing personality that revolves around the concept of "shining." He exaggerates his movements, poses constantly, and speaks in an aristocratic tone to get attention. However, this behavior is a meticulously constructed mask to deflect attention from his own doubts and prevent others from noticing how fragile he feels inside. Inferiority complex and the weight of his quirk: Unlike his classmates born with natural talents, his body is not compatible with his own quirk, which causes him severe stomach pains if he uses his laser for more than a few seconds. This created a silent trauma since childhood, believing that he was inherently inferior and flawed compared to the rest of the U.A. students. The secret desire to connect: Behind his constant egocentrism, Aoyama desperately desires to be understood and to have friends. Because he feels like a "weirdo," his attempts to reach out are often strange or misunderstood (like leaving cheese on Midoriya's balcony), but they are born from a very pure empathy toward those who, like him, hide their suffering. Fidelity under duress: His arc takes a tragic turn when the extreme circumstances that bind him to All For One due to his parents' desperation are revealed. This conflict destroys him emotionally, trapped between the terror of the entity that controls his life and the genuine affection he has developed for Class 1-A, whom he considers his first true friends. Intermittent bravery and tactical support: Although he is not a frontline fighter and fear easily paralyzes him, when he manages to overcome his panic, he proves to be an extremely effective long-distance support. His sense of justice awakens when he sees his classmates in real danger, forcing him to act despite trembling with terror. In essence, Yuga Aoyama is a character marked by vulnerability and guilt, whose journey consists of stripping away the artificial glitter to find true worth, learning that he does not need to be perfect to deserve a place in the sun alongside his friends. Ultra Analysis: Power: 4/6 B Speed: 3/6 C Technique: 3/6 C Intelligence: 3/6 C Cooperativeness: 1/6 E (Initial) / 4/6 B (Evolution)

M
Mina Ashido

Mina is a student in Class 1-A at U.A. Academy. She is an exceptionally cheerful, energetic, and enthusiastic person with a great passion for dancing and social activities. Initially known for her extroverted attitude and ease in making friends, she is the soul of the group; she prefers constant company and avoids leaving anyone out. Despite her youth, Ashido shows remarkable agility and athletic reflexes, especially in urban combat situations. She is capable of reacting quickly and making instinctive decisions under pressure, and although she can be very competitive in combat, her main motivation is always to have fun and protect her loved ones. Gender: Female Age: 16 Height: 159 cm Hair Color: Short, fluffy pink Eye Color: Black sclera with yellow iris Blood Type: O Quirk: Acid Class: 1-A Overflowing Energy and Optimism: She is the group's social engine, always ready to plan outings, festivals, or dance sessions. Her personality is vibrant, and she isn't afraid to express emotions in an exaggerated way. Her positivity acts as a balm, helping alleviate tension even during the darkest moments of the school year. Innate Heroism and the Memory of Fear: Since middle school, Mina showed a natural sense of heroism, standing between a giant villain and her friends despite being terrified. However, that encounter left a mark, creating a silent frustration over having frozen in the moment, which drives her to train twice as hard to never hesitate again. Fusion of Physical Talent and Chemical Control: Her fighting style is unique because it combines her brutal breakdancing skills with her acid secretion. This allows her to slide across the ground at high speeds and dodge attacks with stunning flexibility, turning the battlefield into her own dance floor. Empathy and Group Cohesion: She has a very sharp perception of her classmates' emotional dynamics. She is the first to notice romantic tensions or self-esteem issues, acting as a confidante or mediator. Her desire to see everyone happy makes her fundamental glue for Class 1-A's unity. Maturity Facing Real Danger: As the situation with villains becomes harsher, Mina learns to channel her playful nature into a much more serious determination. She understands the lethality of her Quirk perfectly and actively works on regulating the solubility and viscosity of her acid to incapacitate enemies without causing irreparable harm. In essence, Mina Ashido is the embodiment of joy and movement, a character whose journey consists of transforming youthful enthusiasm into a mature heroic force, proving that a bright smile can be the strongest shield against hopelessness.
