Anyone familiar with the 'Another World's trope, or in anime terms 'Isekai', would know already.
An ordinary guy getting transported/reincarnated/summoned/ in another world after getting run over by a truck and becoming overpowered, slaying the Demon King, made a harem of beautiful and cute girls, and then lived happily ever after.
Now then what if right after the guy that got into another world returns back to his world?
"Unfortunately since you were already long dead for several hundred years, the Earth that you knew was different than you remembered." Gabriella warned the man.
"In order for you to go back, you'll have to be reincarnated to a new body." she continued.
"Reincarnated, so that means I'll start my life living as a baby?" the man asked.
"There's also that problem. A side effect from getting reincarnated is that you could only recover your memories once you turned at least seven years old. As a man with vast experience, your soul is simply too much for a baby to handle. The mind of a newborn baby can't possibly store your soul, the mind of your incarnation needs to be developed physically first."
The man started pondering about it for a while and then nodded.
"Then I will be in your care, my Goddess."
The Goddess nods his head.
"Very well. I shall start the process to send you on your way."
Suddenly the Goddess' body started to shine with Divine Light.
And then before the man could even comprehend what happened, his consciousness blacked out...
***
There was a boy sitting up on his bed with a severe headache.
His name is Akira Kurosawa.
His face is puzzled with his eyes reflecting his emotions filled with confusion.
Akira just dreamed of something really amazing.
In that dream he lived an entire lifetime in a different world. Normally when he woke up he would forget about his dream entirely.
But not this time.
Akira could still clearly remember everything about the dream. It's like he lived as a different person, or watching a movie in a first person view.
"No that's not it... It must be because of the Goddess. It's just now that my memories just been unsealed." Akira said, as if he was sure of it.
After that, he stayed up sitting up on his bed for a while. He closed his eyes and started digesting the memories.
Akira was like a monk in meditation.
[Ding! Successfully unsealed your memories that your incarnation can handle!]
When Akira heard the familiar mechanical sound in his mind, he rubbed his eyes before looking at the floating screen again.
"I thought I wouldn't get any of my powers once I got back. Why is the System still working?"
Akira checked the system on his mind.
[Name: Akira Kurosawa
Age: 12
Sex: Male]
"It worked just like normal. The Goddess might have purposefully left this." Akira thanked her in his mind.
Next he started checking his stats.
A 3D holographic model was created showing his full body. The numbers were displayed, then charts and graphs started to appear.
He looked just like any other kid. Black hair, brown sharp narrow eyes, slightly tan skin, and a slightly above average look for a boy his age.
Back in the previous world he had the ideal looks of a valiant handsome man suited for a hero that would save the world. But now he just looks normal.
"I'm really now just an ordinary person." Akira said, he had a smile on his face seeing how low his stats are.
If this was back in the world he previously came from, even a mere slime would kill him.
[The Goddess of Time and Space Gabriella sent you a gift of gratitude!]
[Stat Leveling Boost x3: Increases stat increase by 10x!]
"Thank you very much." Akira prayed to the Goddess and thanked her.
Gabriella and his previous reincarnation have a relationship that is closer than any ordinary mortal and a Divine being would have.
He was saved by Gabriella many times and Gabriella owed him greatly for saving the world.
After doing his prayers, he was already planning on setting up a shrine for him to worship in the future.

"Never thought the incarnation I'd get would be of East Asian ethnicity though... I forgot I was even one before I was transmigrated." Akira murmured.
After he finished digesting all the memories, Akira rubbed his temples.
Before his memories were unsealed, Akira was a timid boy. He gets shy to strangers, and gets bullied from time to time.
His father worked overseas, and the mother was a housewife taking care of him and his little sister.
"Akira, wake up already and start preparing for school."
Akira could hear the familiar voice from his mother. It was his first time hearing after getting his memories back. He found it strangely soothing.
Yuki Kurosawa. Age 32 and Akira's mother.
And then the doors of his room opened.
"Big brotheeer~ Hurry up! Hurry up!"
Another voice came ringing down his ears. Akira saw a cute little girl that just looked like him, black hair and round brown eyes.
Seeing his little sister so energetic so early in the morning, his lips curled up with a warm smile.
Hanako Kurosawa. Age 11 and Akira's little sister.
"Alright alright, I'm waking up."
After a while they went downstairs.
There was some good looking breakfast served on the table. From the main dishes to the side dishes, they looked all really delicious that will up your appetite.
Akira savored every food he eats.
"Wow! This is really delicious, Mom." Akira couldn't help but say it wholeheartedly.
"What's wrong with you? It was your favorite, so you eat it everyday." She said.
Although she said it without being too bothered by what Akira said, there was a smile on her face showing that she loved it.
She also felt a little strange of Akira, like the vibe she's feeling from him changed. He doesn't feel that timid than he looks.
"Well, but for some reason it was much tastier than usual." Akira said sincerely, there's no denying that he really loved it.
Apparently the dish was called Omelette-Rice. An ordinary dish with fried rice inside a rolled up egg.
"You won't get extra allowance you know?" she stared at Akira weirdly.
For some reason she just felt something changed with him.
Next he took a bath together with his little sister. After they brushed their teeth they went and changed into their school uniforms.
Akira was in the 1st grade of middle school. His little sister Hanako is still in 6th grade of elementary.
His little sister Hanako is uniform with her cute red backpack.
Akira is wearing shorts and a shirt that was his uniform in school.
"Goodbye~"
"We'll get going, Mom."
"Take care."
This is the life he wanted, a very simple life devoid of responsibilities and expectations.
