Konyaku Haki no Tetsuzuki wa Osumi desu ka? Daini no Jinsei wo Ouka shiyou to Omottara, Guild wo Tatenaosu Koto ni Narimashita

Patricia, daughter of Count Sainraime, was rather happy when her fiancé, Claude, told her he wanted to break off their engagement. She had already prepared perfectly for this day...all the documents that proved that she could receive a certain amount of money as compensation. Claude couldn't believe his eyes, for Patricia was a carefree girl in front of him for a long time. He didn't know that Patricia remembered her previous life as Akiko, an office worker, on her sixteenth birthday. There was no choice for him but to sign the documents.

With the money, Patricia bought her parents a second house and headed off to a town far away. She wanted to find a place to work. But when she found a job at a mercenary guild, it was a tough place...!
