The Main Heroines Are Trying to Kill Me

After shedding bitter tears to save a hopeless dark fantasy world, I destroyed everything, killed the Demon Lord, and then returned to the past. Now I'm trying to save the world with the system I received as a regression bonus, but... The main heroines have awakened their memories from the previous timeline. Well, fuck.
