A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory?

System: “Your goal is to become the most prestigious woman in the kingdom (the Queen)!”

Years later, she met the target by becoming the most prestigious woman (the Empress).
Jiang Pengji: “Well done, no?”

- Description from Novelupdates

I transmigrated into a novel that I was reading.“But of all people, why did it have to be Kamon Vade?!”The problem here is this: the character I transmigrated as was a third-rate villain who appeared at the beginning of the original story, but after he had been accused of attacking the imperial princess, he disappeared and left the stage.“Haah, fine. The novel never said that I died anyway. So, I just need to somehow hold out and endure in the academy, right?”But…Maybe because I refused to exit the novel, ‘death’ keeps following me around.‘Motherfxxxer, this is like the fantasy novel version of Final Destination!’Damn it, I have to survive somehow.And I will! No matter what!
