MTL - Juvenile Medical God - Chapter 31 Who is who?

The eldest son of the assassin aristocrat Tuatha Dé.

The skill, experience, knowledge of the previous life, magic, all of which grows his power as an assassin.

Excellent assassins pass through. He was usually admired as the ideal lord, and behind it wielded a blade as an assassin aristocrat.

I used a cheat to devise a character in a game. Upon regaining consciousness after pressing the play button, I discovered myself embodying the character I had crafted, the ‘Priest of Corruption.’ This character was intentionally created with unfavourable statistics and is widely detested! The sole item in my inventory was the withered hand of a woman, yet could it possibly be the hand of a goddess?

The light is here because the darkness exists. Just like that, the human realm exists because the demon realm is here. And in the great palace of the Blade Empire, a crown touches the peak of its glory before it falls from its grace. Lush Von Blade was the royal crown prince of one of the greatest empires on the southern continent. He is loyal but betrayed.On the other hand, where even the Gods fear to set a foot on, a demon lord abides. His grace and cruelty have been unseen for centuries. He is the supremacy in the three realms. While Lush is the light, he is the darkness. Each exists because the other is here.

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?
