Hikari is a young girl who just got into one of the best hero high schools, UA Academy. While she is learning how to be a hero that people can place their trust in, she also has to worry about finding her real family and learning their origin; heroes who fought with the evil-- or villains who desired for the world to fall into chaos. Her school life even gets more complicated when she comes across an indigo haired young boy that she met in the entrance exams.
