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? Or will he succumb into a conspiracy lurking within the country's borders?

Reincarnated as an Imperial Prince

In the middle of the rising empire of the east lies its capital named Tokyo. There, two palaces stood, the Imperial Palace, which houses the Royal Family of the Yamato Empire, and the Akasaka Palace, a baroque-style architecture palace similar to Hofburg Palace, built primarily for the crown prince.

The three Grand Duchess / Imperial Princesses of Ruthenia are staying in Akasaka Palace for the duration of their visit to the Land of Yamato.

Anastasia was looking out the window as the sun graced her skin with its gentle rays. Her face shows a hint of disappointment as if something bad has happened.

"What's the matter, Anastasia?" her sister, Tiffania, approached her and lay a hand on her shoulder, gently.

"You don't sound so sure. You never sounded so uncertain before. Is there something bothering your mind?" Tiffania asked.

She shrugged. "I miss our home."
