Demon Faced Blacksmith (Naruto Fanfiction)

Died in a gas leak in Tokyo. Woke up in a leaky shack in Konoha with a 3.2 million Ryo debt and a face that makes grown ninjas cross the street. ​I used to be a master blacksmith. Now? I’m a scrawny 17-year-old civilian stuck in a military village, dealing with a "System" that forces me to forge kunai to the beat of annoying pop songs just to pay the rent. ​Let's keep it a hundred: this world is completely unhinged. You got teenagers spitting fireballs, giant tailed demons that can nuke mountains, and literal alien gods waiting in the sky to end the world. And me? I don't have a single drop of chakra. If I step onto a battlefield, I'm just a red smear on the dirt. ​But I refuse to get crushed again. I don't need magic eyes, and I don't need a demon sealed in my gut. I know physics, I know superior metallurgy, and I know how to hustle. ​If I want to survive the cosmic bullshit coming to this village, I need to make myself economically untouchable. I'm going to build revolutionary weapons, hijack the entire supply chain, and monopolize the Fire Country's economy. ​I can't punch a Tailed Beast. But I can sure as hell overcharge the guy who does.
