Time passed, Ichigo was born.
When the original story takes place, Ichigo is fifteen years old and a first-year high school student. During the Thousand-Year War, he is a third-year high school graduate. He didn't go to university.
Purely announced to the real world and Hueco Mundo that Child of Destiny was the Ichigo, raising the surveillance level in Karakura Town by three levels, leaving the Karakura Town guarded by Soul Reaper. Zenosuke Amano, the Zennosuke Explosion the original work, was completely bewildered.
Why? Because every time he sensed a Hollow appear, by the time he got there, the Hollow had already vanished, as if it had never existed. But in such a short time, for a Hollow to have already gone to Hueco Mundo seems a bit too fast, doesn't it?
So he found his role as Grim Soul Reaper inexplicably easy, while secretly, over a dozen families in the streets in front of and behind Kurosaki Clinic, and among the neighbors, had moved away within a few years.
On the way Shin takes Ichigo to and from school every day, the people taking walks, homeless people, old men reading newspapers, and fishermen are all Undead and Fullbringers, yet the Kurosaki Family never notices them.
This level of vigilance is truly remarkable. However, despite Endless warnings, Masaki Kurosaki picked up her Quincy techniques again, which she had long since abandoned. But as a full-time mother, she wasn't practicing very diligently. Furthermore, both she and her husband were hiding their secret from their child, especially Makoto, who didn't want her child to become a Quincy.
Then time came to a crucial point: Ichigo was nine years old.
In the original work, during this year, Ichigo's mother was devoured by a modified Hollow, the Grandfisher, while protecting Ichigo. Then, when Ichigo was thirteen, this thing came back again, trying to eat the Kurosaki siblings who were visiting their graves that morning. Ichigo released Ichigo Spiritual Power and almost killed it. Its last appearance was when it returned as Half-Arrancar to seek revenge on the Kurosaki Family, only to be instantly killed by Isshin with a single slash—that really, really big thing.
Aizen occasionally visits Hueco Mundo over the years because of the second Zanpakuto Jun left behind in Soul Society — the Space Blade. While this sword sounds incredibly powerful, it doesn't actually have the ability to cleave space; it can only sense space.
Therefore, Aizen had actually been frequently traveling between Soul Society and Hueco Mundo since the very beginning, with Metastacia, who devoured Kaien Shiba, or even earlier. However, it's unknown what he used to travel there in the original work. During this period, Aizen Space Kidō, leading to a greater prevalence of modified Hollows in Soul Society compared to the original story.
It's only because the Soul Society in this timeline is much stronger than the one in the original work, with a large number of ruthless mid-to-lower-level Vice-Captain, that the modified Hollows didn't cause too much trouble; they were either dealt with one by one, or they all escaped.
The first half of the year went smoothly, since she was still pregnant at that time. She gave birth to the twin sisters, Karin and Yuzu, on May 6, and then rested for more than half a month before resuming picking up and dropping off Ichigo at school.
July arrived, and World of the Living received a message from the real world saying that the appearance of Hollows in Karakura Town had increased abnormally, and that several modified Hollows had appeared. Jun knew then that the time had come.
So Chun issued an order to the World of the Living: "Monitor in real time; if the attackers are found, then proceed to kill them."
"Mommy~", nine-year-old Ichigo saw his mother from afar and quickly ran over.
"Ichigo ~", she really has the personality of a young lady, picking up her son and kissing him a few times, "Has Ichigo been good today~?"
"Yes, Ichigo is very well-behaved, hehe."
Hello, Aunt Kurosaki ~
Hello~ Shinoka ~
Just then, a man wearing glasses walked over, "Shinoka!"
"Daddy~", the little boy from Shinoka cried out and ran into his father's arms.
Good afternoon, Kurosaki!
Good afternoon, Mr. Shizuoka!
The family's surname is Shizuoka. They moved in earlier this year and are considered neighbors. The two houses are just two streets apart, not far apart at all.
The husband is a business manager at a company, and the wife is a rare working woman in Japan; she runs a chain of restaurants. Therefore, the husband has to pick up the children from school every evening, and the wife takes them to school in the morning.
They didn't have much interaction at first, but after running into each other a few times, they became acquainted, and the two children got along very well, agreeing to go to and from school together. So gradually, whether it was coming to school in the morning or going back in the evening, they basically always went together.
Mr. Shizuoka is very talkative. He's a business manager, after all. Every evening when he goes home, his two children play in front of him, and he and his wife can chat about their children, family, and work. They laugh and talk all the way home, which is very enjoyable.
The Kurosaki Family is quite far from the school; it's a long walk along the riverbank. The children like to play there, but after running around for a while, they get tired and run back to their parents to rest. After walking for a while, they regain their energy.
They walked and played around like this, and were almost home. The Shizuoka family's house was still ahead, while the Kurosaki Family was at the next intersection where they could turn left. The two children were really too tired to run anymore, so they started walking from the riverbank to the embankment. Just then, Ichigo suddenly shouted...
"Mommy, there's a little girl crying!"
The three of them turned around together, but Ichigo had already run off, shouting as he ran.
"Don't jump!"
The little girl had stood up, one foot dangling in the air. Ichigo rushed over, running sideways along the riverbank to catch her. But as he did, he felt something was wrong; it felt like he was touching a wisp of mist.
Little Ichigo slipped. He had used all his strength to catch him, but being only nine years old, he couldn't control his body very well. He lost his balance and spun half a circle, then slipped again, almost falling into the river.
An orange figure suddenly grabbed Ichigo from Ichigo and tossed him ashore. At that moment, Ichigo saw a monster over two meters tall wearing a large Hollowfication Mask appear, its jaws wide open, ready to bite his mother.
Ichigo was terrified and couldn't even scream. Then, a glowing man descended from the sky, kicked the giant monster away with a flying kick, and then another glowing little creature grabbed his mother and brought her back to shore.
"Mr. Shizuoka, you..."
Shizuoka Shinto cracked his knuckles, "Shinoka, take good care of your friend and your friend's mother."
"Understood, Dad!" Shinoka's Spiritual Power surged. "That thing looks tough. Dad, you're not going to be outmatched, are you?"
"Huh!?" Shizuoka Shinto scoffed, shouting, "Who are you talking to, you brat!"
Dressed in office attire, Shizuoka Shinto rolled up his shirt sleeves to his shoulders, twisted his muscular arms, and shouted...
"The Water Full! It is coming!"
"Yay~"
A Little Kappa made of water appeared on Shizuoka Shinto's shoulder. The creature in the water had risen, and Shizuoka Shinto's fist was fully charged. The Little Kappa swung the lotus leaf in its hand, and together with the fist, it slammed down.
Suddenly, the river water was drawn to Shizuoka Shinto's fist, forming a water sphere. Then, a fist imbued with immense Spiritual Power struck the water sphere, shattering the water into a beam of light and creating a tremendous Explosion.
A two-meter-deep crater was blasted open on the opposite bank of the river. The enormous head of the void in the center of the river was hollowed out by a single blow, its entire upper body blasted open, utterly and completely dead.
"Phew~ That feels great!" Shizuoka Shinto smiled and turned around, extending a hand to Masaki Kurosaki in a handshake gesture. "Undead Shizuoka Shinto. Kurosaki, would you like to get to know each other again?"
"The Undead? Ah! Who are you?"
"Hey, it's the people who protect you, like in this situation today."
The other two children are different. Ichigo is very cheerful; he became withdrawn after witnessing his mother being eaten by a Hollow. He has been able to see ghosts since he was a child and has even killed a Hollow, so his acceptance of supernatural phenomena is exceptionally high.
He was jumping around in his arms, hugging Shizuoka Shinoka, exclaiming, "So cool, Shinoka! What's going on with you!? You're amazing!"
Shinoka was embarrassed by the praise. He and Ichigo were truly good friends. There weren't many kids his age among the Undead, and he cherished having a friend of similar age like Ichigo.
The little guy scratched his head, "Hehe~, isn't that amazing? Ichigo, you're amazing too!"
"Hehehe," Ichigo foolishly, realizing that these two kids didn't care at all who the other was.
Shizuoka Shinto said, "Let's go, Kurosaki. Kurosaki. Given what's happened, it seems we need to talk to you about the children."
Masaki Kurosaki very embarrassed, but also somewhat wary. "Alright then, Mr. Shizuoka, please."
Just as the two families were about to leave, Ichigo asked, "Uncle Shizuoka, is that cave alright?"
Don't worry, someone will take care of it.
A dozen minutes later, the Kurosaki Clinic family arrived at the Shizuoka clinic, and the entire Kurosaki Family also arrived. Shizuoka Shinto spoke first.
"Shizuoka Shinto, one of the seven Undead Fusion Warriors "
"Shizuoka Airyu, the Undead of the seven Fusion Warriors "
"Shizuoka Shinoka, the Undead, the Undead, ugh~ he's just an Undead."
"Hello~", the Kurosaki couple sounded a bit timid, because they had already communicated with Urahara Shop and knew that there were only seven Fusion Warriors among the Undead, belonging to the Captain-level.
Shizuoka Shinto snorted coldly, "Jūshirō years ago, Endless- san came and informed you. Yet today, you two show no remorse whatsoever. So, does your family want a few people to die before you start making changes?"
"What do you mean by that?" Isshin Kurosaki, somewhat annoyed.
"Should I be the one asking you that? I just saved your wife's life, otherwise you'd be a widow by now!"
Isshin was completely bewildered, which gave Mi a chance to tell Isshin what had just happened. Isshin exclaimed in surprise, thanking Shizuoka Shinto profusely. Shizuoka Shinto was furious.
"So what do you two mean? You're saying we can keep being bodyguards for your family, no problem, you can even replace them with other bodyguards, what's your intention?"
Isshin grasped the key point. "Why do you need to protect our home?"
"Because of your son!" Shizuoka Shinto pointed at Ichigo, "He is the Child of Destiny foretold by our Lord. He will inevitably become the instigator of turmoil in Soul Society and Hueco Mundo, unless..."
"Unless what!?" the couple asked quickly.
"Unless you are willing to let your daughter take her place, choose—a son or a daughter, or your third child—your children will inevitably be the Child of Destiny."
The Kurosaki couple were dumbfounded.
"Why?"
