DxD: I Steal Luck - Chapter 326: Blast Space, the Power of the Transcendent!

The salaryman who had a dream of becoming a CEO has finally succeeded.

However…

There was no one. No one was around to celebrate his success. Then on his first day of work, news of the death of a former colleague that he had laid off came. Additionally, his family left him, who was only concerned about the company.

The life he thought was right crumbled right in front of him. Where the heck did it all go wrong? Then, another opportunity came for Han Yoo-hyun, who had plunged down into despair.

This time, for sure. He was going to live properly. He was going to change it all with his whole being. The new life that Han Yoo-hyun was creating.

That valued life that will outshine any other is unfolding now!

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?

When the new snow begins, the full moon will be in the sky

The shadows are tiled below

Shining silver on it

And you walked towards me with a smile

Between the moon and snow

You are the third stunning color
