I was reincarnated as a genius blacksmith of the Demonic Cult in a martial arts novel.
Since famed swords were too easy, I decided to forge ‘Demon Swords’ imbued with my own will and soul.

My method is to foster a warrior's growth by intentionally pushing them to their limits, only to cap it off with a magnificent finale.

After all, isn't a weapon's true purpose to help its wielder?
However, the reactions of the martial artists who have completed their growth are a bit... strange.

"Blacksmith! Bring this sword back to life, now! That's an order! Now...!"

"We did it! We really did it! Finally, we... Lord Demon Sword?"

"You damn bastard... How could you just say that and leave? Now I'm left all alone again..."

"What are you talking about?"
"An adult? No!"
"Without you, what in the world am I supposed to live for?!"
"If it's not with you, then everything is meaningless...!"

After all the trouble I went through to make them grow, they're just muttering to a lifeless piece of iron.
I just don't get it.
