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.

I’m a roleplayer. A gamer who creates characters according to their classes and happily acts as them.“Don’t… Touch me……”“Talk more and see if you can handle my wrath……”My current character was a Demon Knight who kept a Demon sealed in his right arm! One day while I was just acting as my character and enjoying the game as usual……“Log out.”[This command cannot be carried out.]“……? Log out.”[This command cannot be carried out.]“……???”And as if not being able to log out wasn’t enough…“You disgusting Demon! So you finally took over Sir Demon Knight’s body!”“My eyes cannot be deceived! Sir Demon Knight isn’t that kind!”Because of my damn companions I couldn’t even stop role playing!Can this role playing gamer faithful to their setting ever return to reality?
