27-sai OL, Isekai de Yuujo no Kanri Hajimemasu

A 27 year-old OL transmigrates into an otome game where the player controls a prostitute who punishes the evil-doers of Yoshiwara. However, the one she transmigrates into is a sub-character who works as the brothel madam, a character on the evil-doer's side. Unfavorable a character as she is, she'll definitely survive!
