Kurosawa Yuji opened his eyes and what he saw was the blue sky and the dazzling sun.
He showed a faint smile, with unmistakable excitement in his expression.
Really back!
That is great!
Kurosawa Yuji greedily breathed in the fresh air and the faint fragrance of cherry blossoms.
It is the smell of the sun, the breath of peace.
The cherry trees move with the wind, rose petals fall, students walk to school in groups of two or three on the street, and the schoolgirls in black pleated skirts are young and beautiful, with a mobile figure.
Kurosawa Yuji is a second-year student at Eastern Union who transferred to Sobu High School in Chiba, Japan.
Today is April 1st, the first day of classes at Japanese universities, and it is also a day when cherry blossoms are in full bloom.
Except for Kurosawa Yuji, no one knew that he came from the apocalyptic world that collapsed two years later.
Two years later, on the day of Sobu High School's graduation ceremony, the world changed drastically.
What followed was a world filled with death and rancidity, the air was filled with gunpowder smoke and the smell of blood, the sky was gray, depressing and hopeless.
Humanity has come to an end, and civilization has come to an end.
But he finally had to enable time travel and returned to the most special day of his life.
...
"Student Kurosawa, the school has told me about your situation. I hope you will seize the opportunity, study hard, strive to be admitted to Tokyo University, and bring glory to Sobu College. If you have any problems in your studies and life, you can contact me."
"I understand, professor, I will study hard and take advantage of the opportunities that the school has given me."
When he was in his first year of high school at Eastern Union, he transferred to Chiba Sobu High School as a special second-year student.
He lived up to his status as a special student.
Focus on your studies, do things seriously, keep your distance from the opposite sex, and get the admission letter from Tokyo University with excellent results.
However, who would have imagined that the wonderful university life within their reach had not yet begun and that a new cruel era had begun?
Everything he originally pursued became a phantom, like a bubble, completely destroyed and lost its meaning.
"Professor, I'm sorry."
Kurosawa Yuji said goodbye and carefully closed the office door. Every movement and every move demonstrated etiquette, which made Class J's teacher Yamada very satisfied.
"Bum..."
It was just Yuji's first step when he turned around and accidentally bumped into someone.
He quickly reached out his hand to support the person who was hit by him and lost his balance and was about to fall.
Thin, soft, and with a vaguely sweet taste, unconsciously, she is a girl. However, this delicate fragrance also had a hint of coldness, which made her feel a little familiar.
"Excuse me..."
Yuji looked up and saw a familiar and cold girl.
It's her. Just like in memory, the dignified appearance, the long black hair over the shoulders, the pretty and beautiful face, the crystal clear skin like snow, the combination of the black student uniform and thin black stockings fully show her youthful beauty vividly.
Upon seeing each other again, Yuji's complex emotions gushed out like a tide, and she could no longer suppress them.
Even now, he couldn't completely forget the girl who felt so guilty.
"Yukinoshita Yukino..."
Her classmate, the famous beauty of ice, Sobu High, the head of the Service department.
And... Strictly speaking, it was his first love.
In the last life, when he transferred to Sobu High and saw Yukinoshita Yukino at first sight, he couldn't help but have a good impression of her. It could be said that it was love at first sight. However, like many boys, he hid this slight feeling in his heart.
He understands that his education and ability cannot provide the material conditions for her happiness.
It's better to stop here than to keep waiting and waiting, having an unrealistic fantasy. Waiting for high school graduation, let this relationship fade away with time.
Falling in love is really an unpleasant thing.
"Can you let me go, mate?"
The girl's cold voice reached Yuji's ears, and Yuji recovered from the melancholic memory.
"Sorry, I apologize to you."
Yukinoshita Yukino shot a cold glance at Yuji, her crystal clear eyes seemed to confirm whether Yuji did this on purpose.
"Please be more careful in the future."
"Well, I'll pay attention."
The cherry blossom petals swaying in the wind flew into the hall, a trace of freshness, a trace of brilliance.
He walked past her.
Yuji glanced sideways at the girl beside him. The scene before the two of them parted ways after the apocalypse broke out reappeared clearly after a year, as if it had just happened.
The expression contained in the girl's dark blue eyes was mixed with complex emotions of confirmation, pleading, and desire, but he did not respond in time.
So much so that when I expelled them, there were only empty streets, the girl's figure had disappeared and it was already too late.
"That will never happen again..."
The soft whispering sound reached Yukinoshita's ears, which made her a little worried, and she subconsciously glanced at Yuji, who didn't notice.
There is always something wrong.
Some strange men, are they freshmen?
Yukinoshita couldn't stop thinking.
...
"Now, Kurosawa Yuji, an international student from the Eastern Union, introduces himself..."
"I'm Kurosawa Yuji, it's a pleasure to meet you all..."
Familiar and unfamiliar faces, it's great to see that many people I know are still alive!
Everyone in the classroom looked at the foreign students.
"Everyone welcomes Kurosawa ..."
Mr. Yamada, the principal of the second-year J class, gave up and signaled for the students to calm down.
"Student Kurosawa, go to the seat over there!"
"Right... Teacher..."
Yuji walked towards the last seat in the row near the window.
And the one in front of him was the girl he had just met and had a brief conversation with: Yukinoshita Yukino.
Yuji nodded slightly at her to express his politeness.
Yukino under the snow just looked at Yuji coldly, without any reaction, but there was a sense of surprise in her heart.
Why does Yuji, a transfer student from Eastern Union, know her name?
The girl has this doubt, but doesn't ask because of her personality.
Yuji focused on the voice that was about to appear.
one more minute
Arrived.
"Drip, drip..."
Hearing this message, the corners of Yuji's mouth curled up, everything was just like in memory, everything was real.
"The personnel selection has ended, and the binding of the 'Hyperdimensional Human Civilization Salvation System' has begun. You need to bind..."
"Try."
Yuji silently said yes to the choice.
In his last life, also on April 1st, he also heard this mechanical sound, but chose "no" out of caution.
Since then, he never heard the strange mechanical sound again.
Naturally, he thought it was just an auditory hallucination and then forgot it in the corner of his memory.
Until two years later, the world changed drastically, doomsday arrived, and the mechanical sound sounded again.
It is precisely because of the outbreak of the end of the world, the sharp decline in population, that the "reason of human civilization" has been severely damaged, and the "human civilization rescue system in hyperspace-time" has lost almost all its functions.
He missed an opportunity to save human civilization.
Every night, when people are quiet, he remains in regret and sadness. He couldn't get past his own level. Originally... many people wouldn't have died.
"Binding was successful."
"Hello, I am the auxiliary elf of the 'Extra-Space Human Civilization Salvation System', please give me a name..."
"Sora."
"Bearing the name, the elf assistant Sora is at your service."
Yuji's eyes remained on the podium, but his consciousness was communicating with Sora.
"I need information about the 'Hyperdimensional Human Civilization Salvation System'."
The 'Hyperdimensional Human Civilization Salvation System' is dedicated to saving human civilization by slowing down or preventing the destruction of human civilization. Users of the system will travel from one apocalyptic world to another to complete tasks and obtain rewards in order to save human civilization in this world, the purpose of which is as follows:
It's exploring the rest of the world to find a way to save your world!
"The last time I went to the doomsday world..."
"This world, Tokyo time, 2019:4 on April 2, [-]."
There are fifteen hours left, there isn't much time left.
"What world is there now?"
"Currently, the only apocalyptic world that can be accessed is 'Lonely Doomsday'."
"Whether people or items can be transported."
A D-level beginner user cannot carry more than ten kilograms of supplies and cannot bring people. The system will provide assistance.
"Help someone who..."
If he cannot bring people with him, he naturally hopes to bring people who can help him.
Even though he has the experience of the previous life, but deep down, he is just an extra memory, a courage to deal with the catastrophe of doomsday, and a sense of sacrifice... [ordinary person].
He's just an [ordinary person].
"The following list of people can become helpers."
Yuji took a quick look and found a common trait of assistants.
"Why are they all women?"
"Only men and women can guarantee the continuity of humanity. When the system user is a man, the assistant must be a woman."
"Can I nominate someone?"
"Currently it is not possible to specify a helper, the system selects a helper randomly."
"Does the facilitator who has entered the doomsday world know the existence and mission of the system?"
"The system will not tell the assistant any information about the system and tasks."
"If two of us die in the mission world, what will happen to us? If one of us dies, what will happen to the other?"
"Insufficient authority to respond."
"After the mission is over, what will happen to the two of us?"
System users will not be affected and will remain in the state they were in when completing the quest. The wizard will lose all memories of having been in the quest world.
"The assistant and I survived until the end, there is a hidden reward..."
"Insufficient authority to respond."
"Then..." Yuji then asked many more questions. But with only D level, he would hardly be able to get much useful information.
If you want to know more information, you must increase the authority.
...
Ten pounds of supplies isn't much, and it's only used to store food and water, and it doesn't last very long.
So, Yuji rushed to the supermarket to buy a small amount of compressed biscuits and chocolates, and also bought covers on the way.
After that, I went to pharmacies and military stores to buy medical bandages, powdered alcohol, anti-inflammatory drugs, pocket knives, magnesium rods, compass needles, items commonly used for survival in the wild.
Yuji used the Internet to download electronic materials related to field survival, machinery, electricity, animals and plants, etc. onto his mobile phone.
Two cell phones, two solar charging treasures.
This was what Yuji had prepared for the world of 'Lonely Doomsday'.
But before he officially entered doomsday, he still had to do one more thing.
Sending emails regularly to countries and governments. After all, he couldn't guarantee that he would be able to complete the mission successfully and return alive.
"I'm a late three year traveler, please don't take this as a joke, I'm serious."
"Today is July 7, 2019. The following are some important events that will happen in the future. Please read the entire article before carefully judging its authenticity..."
"On July 7, 2019, a fire broke out at KyoAni Animation Production Company's "First Studio" in Japan..."
"August 2019, 8, Eastern Union..."

I hope this life never sees the end of the world again.
Humanity will surely win! An ordinary person who witnessed the end of human civilization.
...
Yuji recorded the information about the end of the world in the most concise words in his memory. Precious information exchanged for countless blood and lives, including the time and place of the outbreak in the past few days, the type of crisis, and the effective response methods of human beings.
If there was still time, he would like to attach images of cataclysmic creatures so that countries could prevent them more effectively. The tsundere girl with golden twin ponytails he had met in his past life was a good candidate. Drawing skills were a problem, but the most important reason was that he could keep the secret and be trusted.
There's just no time now.
Considering the trust issues of various countries, Yuji attached a long list and some information. These are the materials he obtained from the Humanity Coalition Government in the past few days. For all countries, the list and related materials are of great value.
After Yuji finished writing the email and added the recipient's mailbox, he let out a sigh of relief as he leaned back in his chair.
With this information, even if there is only one day left before the end of the world, countries choose to believe this information and make corresponding preparations, and human beings can reduce huge losses.
The mailboxes of various countries are also the secret mailboxes of each country that he has memorized, ensuring that this mail can enter the eyes of people with sufficient rights and status.
The biggest advantage of being a traveler is the advantage of information.
Yuji also prepared another version of the email, which was sent on December 12, 2020, and the recipient was someone he knew in his previous life.
He believes that after the country confirms its problem, he will take care of them based on the value of his notice. At least, this can make their life better.
"Everything that could be done has been done, and the next thing I have to face alone."
Facing the unknown apocalyptic world, he was inevitably a little nervous, but he also had curiosity and anticipation.
What kind of apocalyptic world is "Lonely Doomsday"? Is it the same kind of catastrophic doomsday he experienced?
Who will be the assistant randomly selected by the system.
"'Lonely Doom' is activated, and system users will enter the world of 'Lonely Doom' in ten seconds. Be prepared."
Auxiliary elf Sora's voice was mechanical and devoid of emotion.
"ten"
...
...
"One"
"Start going in."
Yuji's eyes were blurred and she gradually lost consciousness.
"How do you survive when everyone in the world disappears?"
Vaguely, Yuji heard whispers.
...
