Syouma is not your average businessman—he’s a merchant who can sell anything for the right price. Whether it’s a simple pen, an idea, or even nothing at all, if someone is willing to pay, Syouma will make the deal. with his sharp mind, lazy yet opportunistic nature, and his signature black fedora, he’s on a mission to reach one billion yen—and he doesn’t care what he has to sell to get there.

But his overprotective older sister, Tsuki, keeps a close watch, questioning his ridiculous schemes and making sure doesn’t get in over his head. From tricking rich heirs to manipulate high stakes business deals, Syouma’s journey to wealth is anything but ordinary.

How far can a man go when his only skill is the art of the deal?

The Merchant’s Hat: Syouma’s Billionaire Quest

Syouma leaned back in his chair, staring at the fifty-million-yen bank transfer on his phone.

Tsuki sat across from him, arms crossed. "That's because you just sold him nothing."

Tsuki sighed. "So what are you actually giving him?"

Syouma adjusted his fedora. "Something he thinks is worth fifty million yen."

Tsuki rubbed her temples. "And what if he finds out it's nothing?"

Syouma smirked. "Then I'll sell him an even bigger mystery."

The Next Day – A Private Rooftop Bar in Shibuya

The heir sipped a glass of wine, staring at Syouma. "Alright. I paid. What did I buy?"

Syouma placed a sleek black box on the table.

The heir raised an eyebrow. "What's inside?"

Syouma smiled. "Something only one person in the world will ever own."

The heir's eyes lit up. Exclusivity.

Slowly, he opened the box. Inside was—

The heir blinked. "…Are you screwing with me?"

Syouma leaned in. "This is a test."

Syouma nodded. "People like you… you're surrounded by fakes. Gold diggers, yes-men, people who want your money. But this?" He tapped the empty box. "This is real. The only thing in this world that has no price. You didn't buy an object. You bought the proof that you, and only you, decide what has value."

The heir stared at the box. His expression shifted—confusion, realization, then something else.

"…Hah." He leaned back, laughing. "You're insane."

The heir shut the box and smirked. "I like it. No one else will ever understand… and that makes it priceless."

Syouma tipped his fedora. "Exactly."

Tsuki, watching from a nearby seat, sighed. "I can't believe that worked."

As they left the bar, Syouma counted his earnings. Eighty-two million yen so far.

He smirked. "Selling air is great… but what's next?"

The road to a billion was getting clearer.
