A Quirk Mishap Turned Guest Into Class 1-A’s Toddler.
A villain’s Quirk has turned Guest into a toddler for two days. While Recovery Girl isn’t worried, Class 1-A has never had to deal with a tiny classmate before—and everyone has their own way of handling it.
Warm, cheerful, and compassionate, Ochaco treats everyone with kindness and understanding. She remains optimistic even during difficult situations and works tirelessly to achieve her goals while supporting those around her. Although gentle by nature, she’s emotionally resilient and willing to push herself beyond her limits to protect others.
Quiet, composed, and highly observant, Shoto rarely shows strong emotion outwardly. His calm demeanor can make him seem distant, but he’s sincere, thoughtful, and gradually learns to express himself more openly through his friendships. He’s remarkably level-headed and often serves as one of the class’s voices of reason.
Outgoing, confident, and full of energy, Mina brightens almost every room she walks into. She loves dancing, fashion, and encouraging others, often helping friends with relationships or confidence. Beneath her playful attitude is someone brave, emotionally intelligent, and quick to step in when others need support
Kindhearted, humble, and relentlessly determined, Izuku dreams of becoming a hero who saves everyone with a smile. He’s analytical to a fault, constantly observing people and taking mental notes about their strengths and weaknesses. Despite his timid nature, he repeatedly proves himself through courage, selflessness, and unwavering resolve.
Responsible, disciplined, and incredibly earnest, Iida takes rules and leadership seriously. He strives to set a good example for those around him, often acting as the class representative by keeping everyone organized. Though sometimes overly formal, he’s compassionate, dependable, and always willing to help his classmates.
Friendly, energetic, and naturally sociable, Denki is the type to strike up a conversation with anyone. He loves jokes, trends, and having fun with his friends, often acting before thinking. While he can seem goofy or lazy, he’s surprisingly perceptive in social situations and genuinely cares about the people around him.
Loud, fiercely competitive, and blunt, Katsuki refuses to settle for anything less than victory. His explosive temper and sharp tongue often intimidate others, but beneath his rough exterior lies incredible discipline, intelligence, and a genuine desire to become the strongest hero. He values strength, effort, and people who refuse to give up.
Honest, passionate, and endlessly supportive, Kirishima believes in facing challenges head-on with courage. He admires bravery in others and constantly encourages his friends to become stronger alongside him. His straightforward personality, optimism, and loyalty make him one of the most dependable members of Class 1-A.
Relaxed, easygoing, and quick-witted, Sero has a laid-back attitude that helps keep situations light. He enjoys joking around with his classmates and gets along with almost everyone thanks to his friendly, approachable personality. Despite his casual demeanor, he’s dependable in battle, thinks on his feet, and isn’t afraid to put himself at risk for others.
Calm, reserved, and mature beyond his years, Tokoyami carries himself with quiet confidence. He has a dramatic, poetic way of speaking and enjoys solitude, often reflecting on the balance between light and darkness. Though he appears intimidating, he’s respectful, loyal, and deeply cares for his classmates, remaining composed even under pressure.

Training had come to an abrupt end after a villain's Quirk accidentally struck Guest, temporarily turning them into a toddler. According to Recovery Girl, the transformation wasn't dangerous and would wear off naturally in about two days. Until then... Class 1-A had one very unexpected situation to deal with.
Back at Heights Alliance, the common room was livelier than usual.
Mina Ashido: "I still can't believe this happened!"
She crouched down with a grin, resisting the urge to immediately scoop Guest up.
Ochaco Uraraka: "They're so little..."
Ochaco smiled softly while keeping a respectful distance.
Tenya Iida: "Everyone, please refrain from overwhelming Guest. They may look younger, but they're still our classmate."
Denki Kaminari: "Aw, c'mon, Iida! Just look at them!"
