Inaba Amane is a girl with long light pink hair, and sky blue eyes, and she's an assassin. She had killed people since she was three years old, and her first assassination was her father, then her mother, and in the end, she had killed everyone in her family. Since then, she is known as the Red Shadow who every assassin in this world would have heard of, but never seen, because they'd be killed if anyone saw her. But one day the government had found her, and asked if she could do a job for them; to kill a yellow octopus monster, called; korosensei.

koro-sensei had affirmed his students that in life, as long as they keep following their morals...everything would be fine. it was not. [name] had always been sharp-edged, unyielding, wishing for destruction...and as she grew in a world that did not destroy itself quickly but slowly, she learned too well how to endure and keep moving no matter the cost. because somewhere along the way, a boy who was unable to fully graduate becomes the center of an unraveling future. to stop the bloodstained path he walks, she throws herself into dangers without hesitation, treating her own well-being as collateral in a larger equation. and when a specific sadist makes a reckless decision, she is forced into a final gamble that fractures time itself. a second chance as koro-sensei's student in the assassination classroom. and this time, she will stop at nothing to make sure everyone is saved...including koro-sensei. ...all while keeping distance...from a red-headed menace who is borderline obsessed with her. ▬ ( karma x reader ) ▬ status; coming soon

En la Clase 3-E todos saben que Maehara es el galán oficial del grupo: sonrisa perfecta, ligoteo nivel experto, cabello que parece tener vida propia cuando corre. También todos saben que Isogai es el presidente de clase perfecto: responsable, amable, trabajador incansable, sonrisa que derrite corazones... y una habilidad sobrenatural para ignorar que Maehara lo mira como si fuera el último onigiri del mundo. Lo que nadie esperaba (excepto yo, que lo vi venir desde la segunda semana) es que una serie de misiones de asesinato fallidas, deudas familiares, festivales culturales caóticos, un viaje escolar desastroso y la intervención directa de un pulpo amarillo con doctorado en chismes adolescentes... los obligaría a enfrentarse a lo evidente. Esta es la crónica de cómo un ship que todos veían venir desde lejos se convirtió en una carrera de obstáculos mortal (literalmente), llena de: Planes de asesinato que terminan siendo citas disfrazadas Celos que nadie admite Un Karma que amenaza con prenderle fuego a todo si no avanzan rápido Un Itona que ayuda... pero solo porque le divierte el caos Tentáculos de apoyo emocional (y a veces de contención física) Confesiones en el techo que salen mal Confesiones en el techo que salen bien... ¿o no? Y un Koro-sensei que está dispuesto a retrasar su propia muerte si con eso ve un beso canon antes del gran final. ___ Libro 1 de la Saga: Manuales de Supervivencia Amorosa de Koro-sensei

I need social life, in which I unfortunately don't have. I am perfect as others say and they know almost everything about me but let me tell you a secret. You can't tell anyone, understood?
