Uzumaki Rin carefully put away the ten thousand ryo Tsunade had left him and looked at her with a trace of sympathy.
Not for Tsunade—but for the Senju Clan.
At this rate, their liquid assets were probably already stretched thin. And the reason? Obvious—Tsunade had gambled it all away.
She must be seriously short on money now. Otherwise, there's no way she would've taken even his small stash.
"Tsunade, I'll make a lot of money in the future—so you can gamble as much as you want," Rin said seriously.
He meant it.
Tsunade treated him well. If gambling was what she loved, then fine—he'd fund it. Once he grew stronger, making money wouldn't be a problem. The ninja world was full of rich targets. Take down a few, and that's instant profit.
What was gambling loss compared to that?
"Rin, you're the best! Come here, let me hug you!" Tsunade instantly pulled him into a tight embrace.
For her, gambling wasn't just a habit—it was tied to memories of Hashirama Senju and a way to cope with the loss of Nawaki.
Everyone else told her to stop.
Only Rin had said: "I'll earn money for you to gamble."
That hit differently.
"I… can't breathe…!" Rin struggled, nearly passing out before finally escaping.
"Hurry up and grow up, then earn money for me. I spend fast, you know!" Tsunade said cheerfully before heading inside.
Rin stood there speechless.
Yeah… you definitely do.
That night, he kept thinking about one question:
How do I make money?
Leaving Konoha to rob wealthy targets? That would work—but he didn't want to leave yet. And Tsunade might not even accept that kind of money.
So the next day, after arriving at the academy—
He was still stuck.
"Rin, good morning!" Kurenai Yuhi greeted him happily.
"You're even prettier today," Rin replied casually.
"Th-that's not true…" Kurenai blushed instantly.
After chatting for a bit, class started. Rin lay on his desk as usual, pretending to sleep while thinking.
At lunchtime, still nothing.
"Red, what makes the most money?" Rin suddenly asked.
"Doing missions," she replied innocently. "Higher rank missions pay more."
…Yeah, that's not helpful.
"Then what's the most expensive thing in Konoha?"
"Hmm… I don't know. But my mom always complains that ninja tools keep getting more expensive. Especially explosive tags—they're really costly now."
Rin froze.
Explosive tags.
Of course.
No matter the world—weapons = profit.
And that immediately reminded him of one person:
Konan.
Six hundred billion explosive tags.
At 400 ryo each… that's 240 trillion ryo.
Forget the Fire Daimyo—even he couldn't match that.
That's true wealth.
"Red, I've decided—I'm going into the weapons business! When that happens, just take as many explosive tags as you want from me. Free of charge!"
He was already imagining mass-producing them endlessly with chakra.
A perfect plan.
Three days later—
Reality hit him like a truck.
He went to Jiraiya to learn a similar technique.
"Nope," Jiraiya said. "You don't have the right chakra nature."
"And even if you did, chakra-created tags expire quickly. Plus, only the creator can use them. You can't sell them."
…
Dream shattered.
Yesterday: future richest man.
Today: broke kid again.
"However," Jiraiya added, "you can make money by selling ninjutsu sealing scrolls."
That caught Rin's attention.
Sealing techniques… like the ones used by Tenten?
But after hearing the explanation, he realized—it wasn't that simple.
There were two systems:
Summoning / space-time storage scrolls → like Tenten's weapon scrollsNinjutsu sealing scrolls → pre-stored techniques, similar to explosive tags but far more advanced
The problem?
Difficulty.
If making an explosive tag is level 1…
Then sealing a jutsu is level 9.9.
And if it fails?
The jutsu explodes in your face.
Meaning:
Defensive jutsu → survivableOffensive jutsu → you're dead
That's why they're rare.
Rin thought for a moment…
Then grinned.
Problems?
Sealing complexity → ask Kushina UzumakiExplosion risk → use Shadow ClonesMass production → solved
Perfect.
"I've decided. I'm doing this," Rin said confidently.
"Old man, teach me the space-time storage technique first."
His path to becoming the richest man in the ninja world… had officially begun.
