   Summary

   Cassandra Cain, Gotham's silent protector and master of martial arts, is on a new mission for Batman.
   Her target: U.A. High School in Japan.
   With All For One's sinister activities rumored to be connected to the prestigious academy, Cassandra must go undercover as a student. Blending into the world of young heroes, she navigates friendships, rivalries, and intense training, all while secretly gathering intel on the elusive villain. As well as looking out for Batman's old acquaintance All Might, can Cassandra uncover All For One’s plans before it’s too late? Will this be a simple mission? Unfortunately for her just like all other emotionally challenged Bats—she gets attached.
