I’m the Villainess, So I’m Taming the Final Boss, Vol. 2 (manga)

Change the storyline at all costs!
Armed with memories of her past life, Aileen d’Autriche is dodging the flags for a bad ending like a pro. With talented lackeys partners at her disposal, plenty of demons to bribe for information, and a new business plan to exploit the rich, things are going smoothly…But how is one to deal with a problem they have no prior knowledge of?
Turns out, Aileen isn’t the only one with memories of a past life, and between both of their meddling, there’s no telling where the story is headed now!
