Binbou Reijou no Kanchigai Seijo-den: Okane no Tame ni Doryoku shitetara, Ouzoku Harem ga Dekiteimashita!?

Sophia became an adventurer because of hardships, even though she was a baron. But one day, she died in a dungeon, and before she knew it, she went back to when she was a baby!

"And from then on, I did my best while training hard."

A glittering smile and highly accurate magic and you have a perfect Sophia! But when she turned 15, her father told her that he had an illness and she ended up becoming an adventurer to earn money for his medical expenses.

"Since this happened, I will make use of my memories and experiences from my previous life, earn money with haste and retire quickly!"

But while I was adventuring, the princes somehow gathered and everyone started treating me like a saint. And in the end, I ended up fighting a nasty person doing something illegal?
