Rian Edelwein has only one ambition: forge the ultimate weapon.

A former modern-day blacksmith apprentice reincarnated into the prestigious Edelwein martial clan, he has little interest in mastering swordsmanship himself. Instead, he trains his body solely so he can forge better and better weapons.

Then he finishes his first masterpiece.

And the sword turns into a beautiful woman.

Now Rian has to deal with Arma, the living embodiment of his finest creation, while navigating Edelwein clan politics and the Selection trial held once every ten years.

He wanted to make the perfect weapon.

He just never expected his weapons to start becoming people.
