Summary
When a quiet stroll through City Z turns into a monster ambush, you're certain it's the end-, until two heroes appear out of nowhere and save your life in an instant. One's a deadly serious cyborg; the other's an unassuming bald guy with an easy smile. Before you can even thank them, they vanish without a trace.
Determined to show your gratitude (and maybe pursue the spark you felt), you track them down online: Genos, S-Class Rank seventeen (17), and Saitama, C-Class Rank three hundred forty-two (342) on the Heroes Association website. Armed with nothing but determination and a plan, you show up at their humble apartment with an unexpected proposition... and absolutely no idea how much chaos-, and heart-, you're about to invite into all your lives.
