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 flipped through a stack of bills, grinning to himself. Thirty-two million yen in three days.

At this rate, he'd be a billionaire in no time.

Tsuki sat across from him, watching with her usual calm expression. "So? What's next?"

Syouma leaned back, propping his feet up on the desk. "Simple. I find someone with too much money and not enough sense."

Tsuki raised an eyebrow. "That shouldn't be hard."

That Evening – A Private Club in Roppongi

The room smelled of expensive cigars and whiskey. Businessmen, celebrities, and politicians lounged in leather chairs, discussing deals worth more money than most people would see in a lifetime.

Syouma strolled in like he owned the place, his black fedora tilted just enough to make him look mysterious.

At the center of the room sat his target—a young heir to a massive family fortune. The guy was wearing a silk suit, a Rolex, and an expression of pure boredom.

Syouma sat down across from him. "You look troubled."

The heir glanced at him. "Who the hell are you?"

Syouma grinned. "Someone who can solve your problem."

The heir scoffed. "You don't even know what my problem is."

Syouma continued. "You've got all the money in the world, but nothing excites you anymore. You've done it all—cars, yachts, private islands… and yet, here you are, miserable."

The heir clenched his jaw. "…Go on."

Syouma smirked. "You need something exclusive. Something no one else has. Something money can't buy."

The heir narrowed his eyes. "And you can get me that?"

Syouma leaned back, tilting his fedora. "For a price."

The room went silent. A few businessmen nearby glanced over.

The heir laughed. "Fifty million yen for something I don't even know about?"

Syouma shrugged. "If you don't buy it, someone else will. And once they have it… you'll never get another chance."

The heir stared at him. His fingers tapped against his glass. His mind was racing.

Then, after a long pause… he smirked.

Syouma grinned. Another deal closed.

Tsuki, who had been watching from a distance, sighed. "So… what exactly did you just sell him?"

Syouma chuckled. "I have no idea."

The road to a billion was getting even shorter.
