The rock economy had spiraled out of control.
Tiny Yuji now owned seventeen "valuable" rocks.
Tiny Takeru had acquired a stick collection he called "wizard equipment."
And somehow—
both of them already had more cash than most kindergarteners should legally possess.
Then—
Takeru noticed something.
Inside the classroom—
the teacher was writing simple math problems on the board.
His eyes widened slightly.
"Oh no," Megumi muttered immediately.
"OH YES," Hakari answered.
Takeru walked into the classroom dramatically.
"Okay tinies."
Tiny Yuji and tiny Takeru immediately sat up straight.
"Yes teacher!"
The actual kindergarten teacher looked deeply confused.
"…Who are you people."
"No time."
Takeru pointed at the board.
"For every math equation you solve…"
A dramatic pause.
"I'll give you money."
The classroom gasped.
Even the other random kindergarteners.
"But there's a twist."
Tiny Takeru leaned forward intensely.
"…A twist…"
"The harder the question…"
Takeru grinned.
"…the more you earn."
Tiny Yuji's eyes sparkled.
"…How much?"
Takeru crossed his arms proudly.
"It ranges from 1000 yen…"
Another dramatic pause.
"…all the way up to 500000 yen."
Silence.
Then the entire classroom exploded.
"FIVE HUNDRED THOUSAND!?"
"THAT'S SO MUCH!"
"WHAT EVEN IS YEN!"
The teacher looked moments from fainting.
Wasuke held his face in his hands from outside the room.
"…He's creating capitalism for children."
Both Mei Mei's looked emotional.
"…He's gifted," young Mei Mei whispered.
Older Mei Mei nodded proudly.
"…A true entrepreneur."
Tiny Takeru slammed both hands onto the desk dramatically.
"I WILL BECOME A MILLIONAIRE."
Tiny Yuji pointed aggressively.
"I WILL BUY DINOSAURS."
"…That's not enough for dinosaurs," Yuji admitted.
"…Then I'll buy TWO."
Takeru immediately wrote a super easy equation on the board.
"Okay."
"2 + 2."
Tiny Yuji instantly raised his hand.
"FOUR!"
Takeru slammed 1000 yen onto the desk dramatically.
"CORRECT!"
The other children started losing their minds.
"HE GOT MONEY!"
"THIS SCHOOL IS AWESOME!"
The teacher looked spiritually destroyed now.
Tiny Takeru pointed proudly.
"GIVE ME HARDER QUESTIONS."
Young Gojo leaned toward Geto.
"…Why does he sound like a gambling addict already."
"…Because he learned from Takeru."
Takeru smiled proudly and wrote another equation.
"12 × 12."
Tiny Takeru stared at it intensely.
Mumbling quietly.
Counting fingers.
Thinking hard.
Then—
his eyes widened.
"144!"
Takeru gasped dramatically.
"…THAT'S MY GOAT."
He handed over more money instantly.
Tiny Takeru screamed victoriously.
"WE'RE RICH!"
Tiny Yuji pointed at the board aggressively.
"GIVE ME A BOSS FIGHT QUESTION."
Hakari nearly collapsed laughing.
"…HE CALLED MATH A BOSS FIGHT."
Then—
Takeru's eyes gleamed dangerously.
"…Alright."
Nanami immediately stepped forward.
"No."
Too late.
Takeru started writing algebra.
The kindergarten teacher finally snapped.
"WHY ARE THERE LETTERS IN THE NUMBERS!?"
Tiny Takeru stared at the equation.
Then slowly smiled.
"…Interesting."
Everyone froze.
Higuruma adjusted his glasses carefully.
"…Why does the child look locked in."
Tiny Yuji pointed at the equation confidently.
"…I don't know what that means."
"…Correct," Yuji admitted.
Tiny Takeru suddenly solved part of it.
Not perfectly.
But enough to shock everyone.
Silence filled the room.
Young Gojo blinked.
"…Okay that's actually insane."
Takeru looked emotional.
"…That's my little dude…"
Tiny Takeru held out his hand proudly.
"…Money please."
And without hesitation—
Takeru paid him.
The math grindset had officially begun.
