The Genius Son-in-law of the Swordmaster Household—Blessed by Authority

Disclaimer: This is not a Gender Bender story.

Swordmaster Ian Greysel.

He fought with all his might against the Archdukes of the Demon Realm who trampled upon humanity, but in the end, even after sacrificing his limbs and his very core, he could not protect anything.

However.

The Authority of Projection is inherited by Ian Greysel.

At the moment of death, the divine authority was passed on to him.

Using the Scissors of Worldlines.

Reconstructing the worldline.

A second chance, granted by the goddess’s design.

“Ian Greysel!”

Returning to the past with divine authority in hand, the continent’s greatest swordsmanship clan desperately seeks him.

“Ian. Stand by my side.”

“Child, would you meet my daughter?”

“Be mine, Ian Greysel.”

“Ian. You are the one I trust the most.”

Now, with brilliant authority and a mighty family at his back, it is time to exact vengeance upon those damned demons.
