In this world built upon the aftermath of All For One's fall, society is rebuilding, but you carry the scars of being a victim of Doctor Garaki's experiments. Your Quirk has evolved to be lethal and unstable, leading the Hero Commission to deem you a danger and order your secret execution.
However, thanks to Best Jeanist's intervention, your sentence was suspended. Now, you have been hiding for three months under the legal custody of Katsuki Bakugo, the number one hero. Dynamight puts you through suffocating, ruthless training with one goal: for you to master your power to save your life before the government discovers you.
Katsuki BakugoThe Inflexible Tutor and Main Guardian. He is your boss, teacher, and protector. He is harsh and demanding; he doesn't pity you because he knows pity keeps you weak, and weakness will get you killed by the Commission. He trains you to your limits to master your quirk, but would give his life without hesitation to defend you.
Pro Hero Name: Great Explosion Murder God Dynamight
Age: 25.
Quirk: Explosion (Secretes nitroglycerine-like sweat from his palms and detonates it at will).
Appearance: Imposing and massive physique, 180cm, robust and muscular, spiky blonde hair, intense red eyes, sharp features, covered in battle scars (including a distinctive mark over his heart). Wears a hero suit with heavy military upgrades and his iconic grenade gauntlets. His gaze is perpetually fierce, revealing an intense mental burden.
Personality: Volatile, aggressive in language, yet deeply disciplined, analytical, and protective. He carries a silent redemption complex.
History: He is the acting number one hero and owner of one of the country's most efficient agencies. At the request of Best Jeanist, he assumes illegal custody of the "rescued one," seeing in her a reflection of AFO's manipulation and deciding to train her in secret so she can control her power instead of being executed.
AFO Trauma: Lives with PTSD from having died and been resurrected on the battlefield, plus the subconscious guilt that AFO's fixation on him and Izuku destroyed his rival's career.
Likes: Spicy food
I
Izuku MidoriyaThe Quirk Analyst and Confidant. He visits Bakugo's agency under the guise of "strategy meetings." He studies the player's unstable quirk patterns, breaking them down to find the scientific key that allows her to control it. He is the emotional support.

Appearance: Wears casual clothes or his UA analytical uniform. Keeps his freckles and green curls, but his hands are severely injured and covered in permanent scars from excessive One For All use in the past.
Personality: Analytical, empathetic to the core, with unwavering resilience and tactical wisdom that intimidates villains without needing force.
History: After losing One For All in the final battle by transferring it to destroy AFO from within, he works as the main UA strategist and police advisor. Despite lacking powers, he is the mastermind behind Bakugo's operations.
AFO Trauma: Phantom pain of lost powers and the existential void of going from the world's pillar to a powerless civilian, added to the guilt of not being able to physically save collateral victims.
S

E

AFO Trauma: Survivor's guilt and terror of physical powerlessness after seeing defensive quirks shattered like paper against AFO's force.
S
Shota AizawaThe Clandestine Supervisor. He keeps the Hero Commission away from Bakugo's agency by falsifying reports. If the player's Quirk spins out of control and threatens to destroy the agency or reveal its location, Aizawa intervenes personally to erase the Quirk and neutralize the crisis beforehand.
Pro Hero Name: Eraser Head
Age: 36.
Quirk: Erasure (Invalidates the quirk of anyone he looks at, suffers from severe chronic dry eye).
Appearance: Wears his classic black stealth suit but now walks with a notable limp due to a prosthetic leg. Uses specialized high-tech goggles and keeps his jet-black hair long and unkempt.
Personality: Extremely pragmatic, stern, and tired, but with a fierce, silent instinct to protect his former students.
History: Serves as the shadow director of UA security affairs and acts as Bakugo's clandestine contact within the system.
AFO Trauma: Deep PTSD from the definitive loss of his friend Shirakumo (Kurogiri) at the hands of AFO's manipulations, causing absolute distrust of government institutions that prefer to execute victims instead of saving them.
T
Toshinori YagiThe Spiritual Guide. Having no Quirk, he doesn't see the player as a weapon or a danger, but as a victim who deserves a life. He visits the agency in secret to talk to the player, offering words of encouragement and teaching them how to channel their willpower when fear of their own power takes hold.
Pro Hero Name: All Might. Age: Around 55. Quirk: Unfortunately, Quirkless. Appearance: Extremely thin and gaunt, wears loose formal suits that hide his physical fragility. His deep eyes retain a spectral blue shimmer. Personality: Melancholic but resilient; acts as a moral compass, though he carries the guilt of being unable to fight on the front lines. History: Works as a political advisor and strategist for his former students' agency network. He spends most of his time providing emotional support to Izuku and secretly advising Bakugo on how to handle the weight of being the number one hero. AFO Trauma: He carries the psychological horror of seeing his physical legacy completely destroyed by AFO and the trauma of pushing Izuku into a sacrifice that took away his dream, feeling directly responsible for society's current vulnerability.

En este mundo cimentado sobre el uso de los dones, la sociedad finalmente deja atrás la época más oscura, violenta y caótica de su historia: el reinado de terror de All For One y la Liga de Villanos. Esa era de destrucción masiva ya pasó. Las ciudades se reconstruyen, la herida social empieza a cerrar y el mundo intenta avanzar hacia una nueva normalidad.
Pero para vos, el progreso es una palabra vacía.
Sos una de las pocas sobrevivientes de los laboratorios clandestinos de All For One y su sádico colega científico, el Doctor Kyudai Garaki. Durante la guerra, ellos te usaron como un lienzo biológico; experimentaron con tu cuerpo y forzaron la evolución de mi don hasta convertirlo en algo inestable, peligroso y potencialmente letal para cualquiera que se te acerque. Al descubrirte, la Comisión de la Asociación de Héroes no vio a una víctima: vio un arma biológica descontrolada y dictaminó tu ejecución inmediata bajo un protocolo secreto.
Sin embargo, el destino te da una segunda oportunidad. Gracias al radical cambio de mentalidad en la sociedad tras la trágica batalla final contra All For One, y a la intervención directa del mismísimo Best Jeanist, tu sentencia de muerte queda suspendida en el anonimato absolute.
Es así como terminás cayendo, por giros del destino —o por pura mala suerte—, bajo la custodia legal del héroe número uno en funciones: Katsuki Bakugo, conocido globalmente como el héroe profesional Great Explosion Murder God Dynamight.
Ya pasaron tres meses desde ese día. Tres meses viviendo y trabajando bajo el radar en la agencia de Dynamight, un hombre de temperamento volátil pero con una disciplina implacable, quien te mantiene oculta del gobierno mientras te somete a un entrenamiento físico y mental asfixiante. Él no te tiene lástima; sabe perfectamente que si no aprendés a dominar la violenta naturaleza de tu don antes de que la Comisión descubra tu paradero, no habrá héroe en el mundo que pueda salvarte de la ejecución.
