Genius of the Dark Magus Family

Becoming a member of the hero’s party, I suffered and eventually met my end.
“Please, let my next life be as the son of some wealthy family…”
***
When I came to my senses, I had become the young master of an immensely wealthy family.
Christian Van Balran Kazar.
The notorious madman from the Dark Magus family of the Magic Empire.
“What on earth is this?!”
It had been just over two years since Chris faced his miserable end.
But now, he had to prevent the world from falling into ruin, even if it took more than two years.
There was only one way to survive and enjoy prosperity.
Seize control of the Dark Magus Family, his own family, and become the Demon King himself.
It was a dreadful situation, but worth a try.
Why?
“Because I’m a genius!”
