Mineral researcher Isuzu loses consciousness while working overtime, and when she wakes up, she finds herself reincarnated as Mahalia, the villainess of an otome game she was playing to kill time... and she has just been told by the prince that their engagement is broken off. She can't let her life of downfall follow the game's lead! After fleeing from the royal palace, she ends up in a coal mine deep in the mountains. Picked up by Abel, the leader of the mine, Isuzu abandons her life as Mahalia, opting for a life on the run, and proposes "steel production using coal (coke)," a method that has not yet been established in this world. Using the knowledge from her previous life, she aims to advance civilization and start an industrial revolution! (Source: Kodansha, translated)
