Chapter 1: Heroes of Yester-decades

With All For One defeated, All Might's hero career fell into irrelevance. As the hero industry evolved more and more into an entertainment first industry, the ever weakening pro hero found himself unable to keep up in a world devoid of villains and thus a need for real heroism. Forgotten by most, struggling to make ends meet and helplessly watching as the values of heroes being warped by fame and fortune, follow the former pro hero All Might as he unintentionally finds himself in a 3 way quarrel between a quirkless activist group, a corrupt hero industry and... his former arch-rival All For One?
