This is not the date I wanted.

"Phantom?! Are you sure?"

Meng Yue couldn't help but widen her eyes in shock. In response, Shidao nodded in affirmation.

"Well, after I was woken up, Phantom said, 'Liang Yi Meng Yue will be in danger later, please go and save her.' Then he disappeared. Then as soon as I untied the rope, I heard the explosion over the residential area and your cry for help, so I rushed over."

Hearing Shidou's words, Mengyue frowned.

The reason why she was in danger was because the phantom turned Origami into a spirit. At first, she thought that the other party wanted to use Origami to exclude her as an alien, but if the other party actually called Shidou to save the situation before that, this possibility could be ruled out.

In other words, the other party intends to turn Origami into an elf, but does not want himself to die.

(For Phantom, Origami must become a spirit. Or is there a reason why she is the better choice?)

For some reason, Meng Yue had an indescribable but very uneasy premonition in her heart.

"Meng Yue?"

Shidou asked with some concern.

"Ah, it's okay."

Meng Yue sighed helplessly. Putting aside the doubts in her mind for the time being, she turned on her phone, contacted Fraxinus, pressed the hands-free button, and reported the situation to Kotori.

[Hey, Sister Mengyue? How is the situation? ]

On the other end of the line, Kotori-chan asked a worried question.

"There were some serious accidents, but Shidou has been found, and neither of us was hurt."

[Really? I'm glad you're alright. I just ran into some trouble here as well.]

"what's going on?"

Meng Yue couldn't help but ask worriedly.

[Alan is attacking us with the Goetia.]

"what?!"

【Hehe~ It’s okay, Sister Mengyue. 】

After chuckling and comforting Mengyue, Qinli's voice sounded a little complacent.

[Although this battle was indeed unfavorable, I think the other side must be more frustrated. After all, after bombing for so long, they only destroyed 12% of Fraxinus's equipment and had to retreat.]

Hearing this, Meng Yue could probably imagine what had happened and a sinister smile appeared on her face.

"Hehe~ You are so bad, Kotori-chan~"

[No~ This is all thanks to Sister Mengyue~]

As they spoke, they both laughed at the same time.

Kotori...has become a bad person. Shidou, who was standing by, couldn't help but think with a smile.

Meng Yue nodded in understanding and pressed the hands-free button on her phone.

"Kotori, ask Tohka and the others how they are doing now."

[Well, they are all on Fraxinus and are not in any danger. I am just worried about you and Mengyue. Ah——they are here.]

As soon as he spoke, the other end of the phone was filled with all kinds of voices.

[Meng Yue! Shidao! Are you okay? I heard something terrible happened. ]

[Darling~ Honey~Are you guys okay? Miku is so worried—]

[I am very unhappy now! Meng Yueru, as my compatriot, actually abandoned the Son of Hurricane, who was my ally, and went to the battlefield alone.]

[Dissatisfied. Xi Xian also wants to help. ]

[Ah~ Being called to the airship suddenly scared Yoshina. What happened? Mengyue-chan, Shidao-kun, are you all ok? ]

[Mengyue-san... Shidou-san... are you... okay...?]

[Hmm - it's too late. Maybe I'm just trying to fit in with the mood. Um, that - Meng Yue and stupid Shidao, are you all right? ]

Hearing the mixed voices on the other end of the phone, Shidao and Mengyue looked at each other and couldn't help laughing.

"Kotori, everyone. I have something to tell you."

Shidou told everyone everything that had just happened, including Origami's transformation into an elf.

"To think that such a thing happened..."

Perhaps because this development was so unexpected, the people on the other end of the phone seemed to find it difficult to digest and fell into a brief silence.

"Everyone, I have an idea about this. Maybe we can solve the problem of Origami's revenge while resolving the conflict between Origami and the elves."

[Is there really such a convenient method? ]

Nanashi's doubtful voice came from the other end of the line. It was not because she doubted Shidou, but because from the current situation, the conflict between Tobiichi Origami and the elves had reached a point where it could not be resolved.

"some!"

After taking a look at Meng Yue, Shidao said firmly,

"Go find Kurumi... and ask her to send me back five years to save Origami's parents who were about to die at the hands of the elves."

13 Truth, Poison, and Reversal (Part )

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

【no! 】

As soon as Shidao put forward his proposal, Kotori's firm opposition came from the other end of the phone.

[Too risky. Shidao, have you forgotten that Tokisaki Kurumi has always been looking for a chance to eat you up?]

"But, but, I think this is indeed a way to solve the problem. As long as we go back in time and rescue Origami's parents who were originally dead, the grudge between Origami and the elves will naturally no longer exist. She can live as a normal person."

Shidou explained hurriedly.

[Perhaps this method is really feasible, then how can Shidao be sure that Tokisaki Kurumi has the ability to go back to the past? ]

"Um... No, I just vaguely felt that..."

In response to Kotori's question, Shidou was speechless and stammered to explain.

Indeed, he didn't know whether Tokisaki Kurumi had the ability to go back to the past. He just thought that the angel who could control time should have this ability.

[For this possibility that is only imagined. I don't agree to let you do such a dangerous thing! 】

"It's okay, Kotori..."

Kotori's attitude was very firm, but Shidou also knew that she was really worried about his safety. He couldn't help but scratch his head in embarrassment.

"No, maybe it's true." At this time, Meng Yue suddenly interrupted and said, "I once heard her say when she was working with Kuang San before that her goal was to go back to the past. Then she should be able to travel through time and space."

"Is this true? Meng Yue."

Shidou couldn't help but said with joy.

"kindness."

Meng Yue nodded affirmatively.

I remember that during the Miku incident, when I and Kurumi went to look for the elves imprisoned by the DEM Society, she once revealed to me her wish to go back thirty years to find the original elves.

As for what he wanted to do? Although he didn't have time to continue because of Tohka's reversal at that time, Meng Yue could guess it almost exactly.

"If we ask Kurumi to help us go back to the past, she probably won't refuse. After all, she probably hasn't used the ability to go back to the past yet, so she might be more than happy to find a test subject to practice with." Meng Yue glanced at Shidao, smiled bitterly, shook her head and said, "However, like Kotori-chan, I don't think much of this method."

"Why? Mengyue, didn't you say this plan is feasible?"

Seeing Mengyue pouring cold water on his proposal, Shidao asked in confusion.

Meng Yue shrugged and analyzed calmly.

"Well, it's not so easy to travel through time and space to save the past. Time paradoxes and the like, although no one has actually traveled through time and space and cannot prove it. But it can't be said that it is something that can be ignored. Shidou, have you ever thought about what the 'present' we are in will become even if you change the 'past'? A small butterfly flapping its wings may cause a huge tornado disaster. What if it puts everyone in danger?"

"This one……"

Shidao was speechless for a moment.

Indeed, if it only involves his own safety, Shidao would not care much. But if it is really as Mengyue said, if the actions in the past may cause harm to everyone now, Shidao really can't act rashly.

"…I'm sorry, I was too naive."

Looking at Shidao who seemed a little lost, Mengyue sighed helplessly and said.

"Of course, I'm not saying that your method is not good, Shidou. Considering the current situation, it can be said to be a very bold and courageous idea. However, we have too little information. How do we go back to the past? What is the price? Who killed Origami's parents five years ago? How did they die? Or who is the unknown fourth spirit? We don't know any of these. In this state, even if we really go back to the past, it will be meaningless. If we accidentally do something wrong and it turns out that you, Shidou, accidentally killed Origami's parents. That would be really hehe——!"

Meng Yue's laughter suddenly stopped in the middle of her half-joking words. An unexpected and severe pain filled Meng Yue's brain, and her pretty face twisted in pain.

"Aaaaaaaaaaaaaaaa!"

"Mengyue!? Mengyue, what's wrong with you?!"

The vision gradually sank into darkness, and Shidou's anxious shouts seemed to fade away and become blurred. At this moment, a cold electronic sound rang in Mengyue's mind.

[——Version update completed——Conditions met——Probability passive triggered——Peek into the future——]

Then, one picture after another flashed through Mengyue's mind like a film.

A shattered full moon... a rain of despair... a completely destroyed city... and within it, a tyrannical spirit like a demon king - Tobiichi Origami...

"...!"

Then, Mengyue's vision returned to the school's infirmary again.

"Mengyue, how are you? Is there anything wrong with your body?"

Seeing Mengyue calm down, Shidou asked with a worried look on his face.

"fine……"

After taking a few quick breaths, Meng Yue shook her head to wake herself up. Then, she found that in her right hand, she was holding her angel, the Sage of Dawn, which had been destroyed by Origami.

(What happened to the scene just now? The origami was reversed?)

Meng Yue couldn't help but think. The Origami that appeared on the screen just now felt very similar to the reversed Tohka that she had seen before.

Obviously, the scene just seen was not real. Although Origami became an elf, it had not yet reversed, and Origami had only destroyed the residential area of ​​Tiangong City. But looking at the Dawn Sage who kept flashing a strange light in his hand, as if warning him, Meng Yue really couldn't treat it as a normal bad daydream.

(Wait... back in time... origami that became a spirit... the unknown fourth spirit from five years ago...)

Several unrelated clues were suddenly connected together, and suddenly, a very bad possibility appeared in Mengyue's mind.

"Kotori-chan!"

Meng Yue picked up the phone and yelled.

[Wow——What's wrong, Sister Mengyue? It's so loud all of a sudden. ]

"Contact Junai and Maria immediately. Have them compare the spiritual waves of the unregistered elf from five years ago with the spiritual waves of Origami who turned into an elf! Hurry!!"

[I, I understand.]

Although she didn't understand why Mengyue suddenly said that, she could feel the anxiety in Mengyue's words. Qinli seemed to have noticed something wrong and hurriedly contacted Junai and Mariya to do the homework.

"Mengyue, what happened?"

Looking at Mengyue who was suddenly fidgeting on the hospital bed, Shidou asked with some concern.

"I have a bad feeling... I hope I'm just overthinking."

Mengyue showed a wry smile on her face and tapped the table with her fingers hurriedly, waiting for Qinli's result.

Then, after a long minute, the person on the other end of the phone finally responded.

"The results are out, Shidao, Mengyue sister."

For some reason, Kotori's voice became frighteningly serious.

"After repeated comparisons by Maria and Maruna, we can be 100% sure that Origami and the unregistered elf whose identity was unknown five years ago are the same elf."

"Varied--!"

Hearing this overly shocking news, Shidou couldn't help but hold his breath and open his eyes as wide as possible.

"Damn it—what a joke!"

Seeing the worst guess in her heart become a reality, Meng Yue gritted her teeth and quickly turned over and got out of bed.

"Shidou, leave now. Go find Kurumi."
