Shocking! The mighty boss of a mercenary group transmigrates into another world as a useless weakling, timid and easily bullied, someone anyone can kick while she's down. She can't get used to living such a miserable life.
When she makes a dazzling return, she sets out on the road to turning her life around. Those who once bullied, humiliated, or insulted her will pay a thousand or ten thousand times over. If she can settle things with her fists, she won't waste her breath. To her, life is about doing whatever makes her feel free and comfortable, and never making herself suffer.
Reborn in another world, she starts a new life and a new way of living. There's no need to spare the feelings of people who treat her badly: she hits back hard. And she cherishes those who treat her kindly.
