Summary
The Sextuplets are the sons of a past pro-hero, Matsuzo Matsuno.
Osomatsu never wanted to become a hero, not like someone with a quirk like his could ever become one, he thought. He always told people that he was too good for hero's duty and would rather do something else.
Was he jealous of his younger brother's quirk? Maybe. He always thought his quirk was just not suitable for being a hero, so he avoided unbeknownst failure, dragging his brothers down with him.
But what happens if he were offered the choice to be one? To actually be someone with responsibility?

Summary
Ume Shinsato's a high-school dropout beautician who lives in a small town with too many people who know about her sukeban days in her formative years. Her past is constantly being drug up with each middle-aged mom who walks into her salon and sits in the chair, and the only people in town who talk to her without treating her like a thug are an oden-stall owner and six weird brothers. When she met the Matsuno boys in high school, she thought of them what everyone else did. Just sextuplets with no differences between them, but as she watched them all drift apart she realized that one boy in particular seemed to catch her eye during their lunch break. Although, he was much more different than that boy was in high school, or so she thought.
