1 — One Year After the Gambling Incident
Tendou and Geto ended up going to Geto's home in the end, and Tendou had a blast with Geto's parents. He also mentioned it to Wasuke, who at the time thought his grandson had finally lost it and become delusional.
Now Geto is in junior school, and the MC's physical age is 7.
A/N: I apologize. I know it was inappropriate for me to send Tendou to a pachinko parlor or casino, but it was a really important plot device and the only way that fit canon. I sincerely apologize to those who thought it was inappropriate. Nor do I support it.
Wasuke Itadori, after leaving for the same pachinko parlor, was shocked to see his own grandson's photo in the "Banned for Life" section for the nth time. He was also given a warning. After that, he decided to go home.
He saw that Tendou had brought a kid home.
Wasuke Itadori:
('...')
"Tendou, who have you brought home?"
Then, turning towards Geto—
"I am sorry if my grandson caused trouble for you. I will pay compensation."
Tendou:
('...')
"Old man, he is my first friend. What compensation are you talking about?"
Wasuke:
Looking at half-dead Geto and then back at his grandson—
"Tell me, brat, how much did you pay him or trouble him?"
Geto:
('...')
Seeing the exchange and misunderstanding, he explained while bowing in greeting—
"Greetings, uncle. My name is Suguru Geto. I am Tendou's friend and his senior. I came today because he invited me home to play games. I hope I did not cause you any trouble by coming unannounced."
Wasuke:
"Go ahead. I am going to bring some snacks."
Tendou:
"Okay, Grandpa! I will take Geto to my room."
Wasuke:
Trying to stop Geto—
"Uhm… uhmm… aa…"
Geto:
Taking his seat, he waved his hand, saying he was fine.
What the hell is this… a scrapyard or something?(Thought to himself.)
Clearly showing some discomfort.
Looking at the mountain of scrap—or rather technical computers and laptops—Tendou had bought.
A/N: Tendou is living in 1998, where there is Python and old, crappy computers. So he asked his grandfather for 1 million yen upfront very nicely. No, he can't just develop iPhones on demand. So I will explain it in this chapter.

FLASHBACK
Tendou:
Acting Sweet—
"Grandfather, please give me half of that lottery I won."
Wasuke:
"Nooooo, brat! I know you would squander it. I am saving it for your future."
____________
After a lot of convincing, Wasuke gave in, thinking he had enough funds for sending Tendou to college anyway, and his retirement savings were also very large. So he gave half the winnings to Tendou, saving the other half for his future.
Now—
Geto, taking the little box from Tendou, saw that there was a game in it.
______________
-------------------------
Tendou:
"Here. This is the game I personally made. It is known as Flappy Bird."
After some hours, Geto left.
But looking at his clean room, Tendou was happy.
No need for imagination—Geto, feeling responsible, helped Tendou clean the room.
Tendou:
"Now that I have modified this computer—"
Looking at the pile of scrap on one side and a modified computer on the other side. He downloaded the interpreter's source code, studied it line by line, and began tailoring it for his own needs. Removing unnecessary modules, tightening memory management, and rewriting bottleneck functions in lower-level C, he slowly reshaped the runtime into something leaner — something built specifically for 2D game logicTendou had bought several discarded computers, each better at different things. Some had slightly faster processors, others had more stable motherboards, and a few had better memory modules. He took them apart one by one, studying their architecture carefully.
Though Wasuke nearly had a heart attack watching the money disappear into what looked like junk,
Tendou wasn't wasting it.
He wasn't creating new hardware.
He was optimizing what already existed.
Using knowledge from his past life, he removed inefficient processes, rewrote low-level routines, and streamlined memory allocation. Instead of relying on the default operating systems, he built a lightweight environment tailored specifically for his needs.
Games and ofc the traps
Tendou placed two small floppy disks beside the modified computer.
"Version one and version two," he muttered.
The first game was simple.
A grid. A moving line. Growing longer with every point consumed.
Snake.
No unnecessary graphics. Just precise collision detection, clean movement logic, and optimized input handling. He had written the core loop in C for speed, while the scoring and UI ran through his modified Python runtime.
It ran flawlessly.
No frame drops.
No stutter.
Even on outdated hardware.
The second game was more ambitious.
A small bird. A scrolling background. Vertical pipes.
"One button," Tendou murmured. "That's all it needs."
Press.
Jump.
Gravity constant applied per frame.
Collision box simplified to reduce processing cost.
Instead of real physics calculations, he used pre-calculated motion tables to reduce CPU strain. The pipes recycled after exiting the screen, eliminating unnecessary object creation
Simple.and Cute.
Most specifically these were discs
Which could be used in any computer and all computers in this era contains disc holder's
So if I were to release these games useing money and invest greatly in popularity and manufacturing
It would bring me profit
Huge profits
Ahahahahhahahah
Wasuke :coming into the room
Bammmmmm
Look what you have done you made a guest do house work and cleaning
After some talks
Wasuke finally agreed to Tendou and took those two sample disc's to his pachinco parler and a game store and had them evaluated
The small firm offered to buy the games outright at 500k yen to 2 million yen
He wanted to call his son but at the end of the day
He remembered that day

There would be part 2 of this chapter then a last filler chapter before starting the high school gojo arc
