This is not the date I wanted.

"What's the situation with Ryougi Yumezuki and the reversed Tobiichi Origami?"

[The spiritual waves of both were very weak, and they both seemed to be in a weak state.]

Are both still alive?... Hearing this unexpected answer, Westcott crossed his legs and tapped the table with his fingers thoughtfully.

[What should I do, Ike? Do you want me to go and collect the spirit crystals of Liang Yi Meng Yue and Yuan Yi Origami now? ]

"No... forget it."

After thinking for a long time, Westcott shook his head gently.

【why? 】

Allen asked confused.

"I don't know either. But my sixth sense tells me that if we take another step forward now, it will only put us at a disadvantage."

It's not that he doubted the ability of his subordinates. But he felt uncomfortable that Liangyi Mengyue didn't choose to kill Origami. Because from the current situation, killing Origami is the best choice.

Moreover, the fact that Shido Gokawa has not shown this yet also makes Westcott very concerned.

Now that Gokawa Shido is able to skillfully use the power of spirits, even if he does not save the spirits, with the power of the Seven Sins that shot down the satellite, he can become an existence that cannot be ignored, whether in the air battle between Allen and Fraxinus or in the battle between Mengyue and Origami.

If Mengyue and Westcott were chess players engaging in a fierce game on a chessboard, then Gokawa Shidao seemed to be a child who suddenly broke in and overturned the chessboard.

Although there was no basis for his argument, Westcott still decided to give up the victory that was so close to him to avoid exposing his trump card.

After hearing his boss's puzzling answer, Alan was silent for a moment and then nodded calmly.

[Got it. I trust your judgment, Ike.]

"Haha... it's really frustrating to stop right when you're about to win the general."

After ending the call with Allen, Westcott leaned back on the sofa, looked up at the ceiling, and couldn't help but let out a long sigh.

"It seems that I can no longer treat you as a simple 'key'. Takamiya - no, Itsuka Shidao."

——————————————————————————I am the dividing line for shifting the battlefield——————————————————————

[Really? How can you be so reckless, Sister Mengyue! ]

"Hahaha - sorry, sorry, I'm wrong, okay? Kotori-chan."

Hearing the almost out-of-control sound coming from the other end of the headset, Meng Yue hurriedly smiled bitterly and apologized.

[Forget it. I don't know why Alan suddenly retreated. But it's best if nothing happens. I'll go over and take you and Origami Tobiichi back for treatment. Wait -?! Why is Tokisaki Kurumi's spiritual wave on your side?!]

"Ahhh - don't worry about what she said. I'll explain it to you later."

Having said that, Meng Yue quickly cut off the communication with Fraxinus and let out a breath of exhaustion.

“Oh my~~”

Seeing Meng Yue, who had just fought the Reversal Spirit to the death with great vigor, hanging up the phone at a loss for words due to Kotori's questioning, Kuang San couldn't help but feel a little amused.

"Well, since DEM has already retreated, I will take my leave, Miss Mengyue."

"Well, thank you, Kurumi. If it weren't for your help, Shidou probably wouldn't have been able to change the past so smoothly."

"Where, I am the one who should say thank you."

She chuckled and shook her head, and a rare gentle light appeared in Kuang San's blood-red eyes.

"Thank you and Mr. Shidou for proving to me that changing the past is not impossible."

As she spoke, Kuang San lifted up her skirt, bowed solemnly to Meng Yue, and then slowly sank into the shadows.

"So……"

Seeing that everything was resolved smoothly, Meng Yue relaxed and lay down on the ground with her arms and legs spread out.

"It hurts, it hurts - ah, it turns out that lying on the ground in the wild is not comfortable at all. The bed at home is better."

Afterwards, the intense pain caused by the bumpy ground touching the wounds on her body made Meng Yue gasp and she quickly turned over and sat up.

"Don't you think so... Tobiichi Origami."

"........."

Next to Mengyue was the reverse elf Tobiichi Origami, who had completely turned into black charcoal and lost consciousness.

With the last arrow, just before it was about to hit Origami, Meng Yue released the spiritual power in the arrow in advance, and all of Origami's own spiritual power that she had collected before was displayed in the form of an explosion.

Under the zero-distance blast of her own highly destructive spiritual power, although Origami Tobiichi did not die, her spiritual outfit was completely destroyed, and her body fell into a coma and shock.

"Honestly, you and I should thank Shidou and Kurumi. If it weren't for those two gunshots, that arrow would have pierced your heart without hesitation."

Meng Yue shrugged and said.

[Machine damaged... 100%...System reoperation...Impossible to operate...]

"I'm sorry, Brunhilde. I treated you like a disposable item. I hope you can meet a truly suitable master next time."

The last voice of "Brunhildr" sounded in her ears. Looking at the mecha that had already been torn to pieces, Meng Yue couldn't help but secretly apologize for the "partner" who helped her.

"Ah... Damn it. I really want to go home, drink Coke, eat potato chips and watch anime leisurely."

Sitting on the desolate land, Meng Yue raised her head, looked up at the crescent moon hanging high in the dark night, and uttered dissatisfied complaints.

Seriously, why would Mengyue go out of her way to fight Origami to the death? And why would Mengyue let the present Origami go after Shidou saved the past?

The reason is simple. If Meng Yue killed the present Origami, would the dead "Origami" conflict with the "present" created after changing the past, creating a new parallel world?

After all, Meng Yue didn’t know what theory the time system of this world was based on.

Will the butterfly reaction caused by changing the past cover the present world like Steins;Gate? Or will it be a branch point to create another parallel world? Or are there other possibilities?

All she could do was to list all the possibilities she could think of and try her best to minimize the negative impact they might cause.

At the same time, she let Origami go for a small personal reason.

If she killed Origami, Mengyue felt that she would most likely choose to leave because of the guilt and would not be able to face everyone.

[——World line fluctuation detected——]

Suddenly, the Dawn Sage in his hand emitted a mysterious fluorescent light, and then the extremely familiar electronic sound rang in Mengyue's mind.

To be honest, it was not until she heard this voice that Meng Yue finally heaved a sigh of relief.

"Tobiichi Origami. To be honest, all I can do for your experience is sympathize with you. If I had the same experience as you, I would probably feel the same way as you, that death is the only way to get rid of my sins and atone for them."

"........."

Although she knew that Origami couldn't hear her voice at this moment, Meng Yue continued to speak to herself.

"But - but! No matter how much you can't forgive yourself, I know that there is someone in this world who wants you to stay no matter what, and has tried his best for it. So even for that person, please -"

Having said that, Meng Yue paused for a moment, and pleaded with Origami in an extremely solemn and sincere tone.

"Please - live well!"

[——The "α" world line jumps to the "β" world line——Start saving the host's information——]

Then the next moment, Liangyi Mengyue felt it clearly.

This world has been changed.

00 The Beginning of a New World

==============================

<One day, I received a text message claiming to be from the future, saying that I would fall in love with a male protagonist in a light novel with harems, and help him collect harems without any regrets… What the hell is this? Aa ...

November 11th, morning.

Ding-ling-ling-ling-ling-ling————

“Hmm…Haa ...

As the alarm clock beside the bed rang disturbingly, the boy who was lying on the bed and sleeping soundly slowly reached out to turn off the alarm clock. After a long yawn, he lifted the quilt and slowly got up from the bed.

"……here it is?"

Rubbing his sleepy eyes, the young man - Gokawa Shido looked around in confusion.

The familiar ceiling, walls, floor, and furniture, it was undoubtedly my room. It seemed that I was quite tired yesterday, after hanging my school uniform on the chair, I fell asleep on the bed.

"……wrong."

As his consciousness gradually regained consciousness, a strange sense of disharmony surged in his heart, causing Shidao to frown.

How did I end up lying on the bed yesterday? What day of the week is today? What happened yesterday?

"...!"

The scattered fragments in his mind were constantly connected, forming the images of the film that appeared in Shidao's mind.

Origami in a pitch-black wedding dress, burning streets, and pitch-black lasers destroying the town.

That's right, yesterday, after learning that she was the culprit who killed her parents, Origami Tobiichi fell into a reversal due to despair after returning to the present, and began to frantically destroy the city.

In order to stop all this, with the help of Kurumi and Mengyue, she went back to the past five years, rescued Origami's parents who had originally died, and changed history.

"Oh right! Where are Origami, Mengyue, and everyone else?"

When Shidou quickly opened the curtains of his room, he saw the familiar East Palace residential area of ​​Tiangong City. Looking to the right, the elf apartment where Tohka and the others lived was standing there intact.

In other words, this is not the Tiangong City that was completely destroyed by Origami after the reversal.

“… Success… huh?”

He pinched his cheeks in disbelief, and after feeling the burning pain in his cheeks, Gokawa Shidao breathed a sigh of relief and lay down on the bed a little exhausted.

"Onii-chan, I'm hungry. Hurry up and get up and come down to cook."

Kotori-chan's leisurely voice came from downstairs.

"Oh wait, I'll be right there."

Shidou hurriedly put on his coat, ran downstairs, and opened the door to the living room.

"Ohhh——You got up really early today, Onii-chan."

At this time, holding a Kabejia lollipop in her mouth, she was lying on the sofa in a rather casual posture watching TV, with her long hair tied into two buns with a white ribbon. Her younger sister, Itsuka Kotori, greeted Shidou with a lively voice.

Normally at this time, as the househusband and brother, Gokawa Shido would not hesitate to lecture his lovely sister for her lazy behavior of eating snacks before breakfast and lying down to watch TV.

But at this moment, he could hardly hold back a smile.

He succeeded. Shidou could now confirm this fact without any hesitation.

Needless to say, after saving Origami's parents, the young Origami did not harbor hatred towards the elves, and naturally lost the opportunity to become an elf. The result was that the fact that the elves had destroyed the town yesterday was eliminated, and it was replaced by a peaceful and ordinary day.

An indescribable sense of accomplishment, peace of mind, and joy filled Shidou's heart, and he couldn't help but hold Kotori's hand.

"Onii-chan?"

"The day of peace—the highest! Long live!"

“Ohhhhhhhh Onii-chan!”

Kotori cheered in unison with Shidou, then tilted her head in confusion.

"What's wrong, Onii-chan? You're so excited so early in the morning. Did something good happen?"

"Hehe - my lovely sister, if I say your brother changed the world yesterday, would you believe it?"

"What is that? Could it be that, Onii-chan, your chuunibyou has relapsed?"

"Forehead……"

Hearing Kotori's silent complaints, Shidou suddenly realized that he was a little emotional and coughed awkwardly.

"Sorry. I'm a little sleepy. I'll go wash my face and then cook. What do you want for breakfast?"

“Special hamburger meat set!”

In order to make Shidou complain, Kotori mentioned the recommended set meal that had just been released by a nearby family restaurant.
