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.

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?

The semi-invincible text, some of the protagonists refer to Dazai Osamu, the stray dog.

Without a heroine, the only thing that can make the hero’s heart beat faster is the bill.
