When We Were Kids

Rini Midoriya is Izuku Midoriya's twin sister, unlike her brother, however, Rini has no idea what she wants to do with her life and thus no motivation to do well in school. She soon finds herself in the dreaded end class 3-E, where she's trained to be an assassin to kill her teacher. After a rigorous year of facing assassins and meeting new classmates, Rini has finally decided on her future plans: to become a hero alongside her brother.

This is a My Hero Academia and Assassination Classroom crossover, but will mostly follow the MHA storyline.

This is also an OCxTodoroki story
