The holidays had just ended, and the campus was once again filled with life as students returned for the new school year.
Inside the bustling school grounds, children chatted and laughed, sharing stories about the fun they'd had during their vacations.
At that moment, a young boy appeared at the school gate.
He looked a little lonely, standing out among the cheerful groups of friends around him.
"Excuse me, could I bother you for a moment?" he asked politely, stopping a student in uniform. "Could you tell me which way Class 2, Grade 5 is?"
"Oh, sure. Go up those stairs, and it's the second classroom on the left," the student replied with a friendly smile.
"Thank you," the boy said, smiling back before heading in that direction.
"So, a new life begins," he murmured to himself, glancing up at the school building ahead.
His name was Ryan—a transmigrator who had just arrived in this world.
Before crossing over, Ryan had been a struggling manga artist, living on the edge of poverty and barely surviving through the small guaranteed pay from an online manga platform.
That life came to an abrupt end one day when, while preparing instant noodles, he accidentally spilled boiling water into a power outlet.
He remembered a sudden electric jolt surging through his body—then nothing but darkness.
When he woke up, he found himself in a completely different world, inhabiting the body of a fifth-grade elementary school student.
By piecing together the memories of the body's original owner, Ryan quickly understood his situation.
The boy whose body he now inhabited was also a transfer student from U.S. But before he could even start his new school life, tragedy struck—his parents, who had been working in Japan, died in an accident.
The inheritance left behind consisted of only a small compensation payment and a modest detached house. It was a sad story.
Still, school had to go on.
For Ryan, who had lived alone before his transmigration, this wasn't too difficult to accept.
In fact, life here seemed better—he had a house and some money. It was far more comfortable than scraping by on instant noodles in his previous world.
And today marked the first day of school. After packing his bag, Ryan set off for class.
In Class 2, Grade 5, a teacher with a buzz cut, black-rimmed glasses, and a briefcase under his arm stood at the podium.
"Ahem… Students, please quiet down," he said, his serious tone immediately silencing the chatter in the room.
He was their homeroom teacher, known for being strict and meticulous. No one dared to disobey him.
"Good. It's a new year and a new semester, and you all look full of energy," the teacher said, adjusting his glasses.
"This semester, we have a new transfer student joining our class. His name is Ryan. He's from U.S. and will be your new classmate.
I hope you'll all be friendly and help each other."
While transfer students weren't unusual, an international student was a rare sight.
Instantly, curiosity filled the room as everyone turned to look at Ryan, who stood beside the teacher, school bag slung over his shoulder.
Whispers spread quietly through the class.
"R–Report!"
Suddenly, the classroom door burst open, and a boy stumbled in, nearly tripping over his own feet before managing to stand upright.
The teacher's face darkened.
"…Nobi Nobita!!!" he barked. "It's only the first day of the new semester, and you're already late again!"
Ryan froze for a moment. Wait—Nobi Nobita?
His eyes widened slightly as he turned to look at the doorway.
When he saw the flustered boy standing there, his heart trembled in disbelief—but outwardly, he stayed calm.
The teacher sighed in frustration. Nobita's clumsy entrance had completely derailed his plan to introduce the new student properly.
He had hoped that this semester would mark a fresh start for Nobita, but it seemed the boy hadn't changed one bit.
"Hahahaha! Nobita's late again!"
"Yeah! If Nobita ever came on time, the sun would rise in the west!"
Laughter erupted from the class.
The loudest came from a large, dark-skinned boy in a yellow shirt with red stripes—Takeshi Goda, better known as Gian—and beside him sat a thin boy with a pointed mouth and cone-shaped hair, wearing a blue shirt and brown shorts—Suneo Honekawa.
The two of them snickered together, poking fun at the hapless Nobita.
Watching this, Ryan raised an eyebrow slightly. He knew these faces all too well.
This was no ordinary world—he had somehow landed in the world of Doraemon.
