This is not the date I wanted.

"Huh - as you can see, the sound from this place can't reach the other side of the city, and it's also very empty. Shouting is very helpful in relieving stress."

Meng Yue let out a breath and said it naturally.

“Hmm…I see…”

Shidou said with some embarrassment. Although he didn't know what Mengyue was complaining about, he felt that it was his fault that the other party had accumulated pressure without his knowledge.

"Feel sorry……"

"Don't take it upon yourself to place strange responsibilities on yourself. This is my own problem."

Meng Yue knocked Shidao's head angrily and said to Shidao.

"Shidou, come and shout too. Maybe the pressure accumulated in his heart is unexpectedly greater than expected."

"No... I don't have any problem."

Shidou smiled bitterly and shook his head, then held the railing and admired the scenery in the distance.

Then——

“Didn’t I tell you I didn’t see anything? Why don’t you believe me?!”

A roar suddenly sounded!

……

"Haqiu!"

Nanashi, who was hiding somewhere, scratched his nose in frustration.

……

“Hu…ha——”

After slowly exhaling, he calmed down his somewhat rapid breathing. Shidou saw Mengyue's meaningful eyes at this time. Shidou realized what he had just done and showed a stiff smile on his face.

"How is it? Much fresher, right?"

"Hmm, hmm...it's indeed much more refreshing..."

Shidou nodded awkwardly.

Hearing Shidou's answer, Mengyue showed a relieved expression.

"That's good. I was very worried when I saw you looking so worried and forcing yourself these past few days."

"Ah... I've been discovered."

Shidou scratched his head in embarrassment. Because of him, the people around him disappeared one by one from the world, but there was no clue about the answer to the question of the Seven Sins. The pressure on Shidou can be imagined. To be honest, Shidou himself thought there was nothing wrong, but he didn't expect that Meng Yue would notice it.

"Of course, I have been keeping an eye on everyone's affairs...Shidou's affairs."

Meng Yue chuckled and answered as a matter of course.

"Dream Moon..."

Looking at Mengyue's face with a gentle smile, Shidao couldn't help but feel some complicated emotions in his heart.

After a moment of silence, Shidou finally made up his mind to tell Mengyue about Nanazai. Mengyue was a person who had been reincarnated once, and in his previous life he was a man. Mengyue only told Shidou about this. Nanazai probably had no way to know about this.

Although there is a possibility that Nanashi can obtain the other person's memory after transforming into a specific person, if this is the case, Nanashi should know that she really saw nothing when she transformed into Shidou.

Most importantly, Shidou couldn't believe that the girl in front of him, showing him her unique consideration, was actually someone else pretending to be her.

Sorry, Kotori! Shidou silently apologized to his sister in his heart.

"Mengyue, I have something I want to tell you."

Meng Yue was not surprised to hear Shidao's words, but a relieved smile appeared on her face.

15 puzzle pieces with answers

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

An hour later, Mengyue followed Shidao to Gokawa's house.

"Well, are you sure that Sister Mengyue is not Qi Zui in disguise?"

After hearing Shidou tell Mengyue about Nanashi's impersonation, Kotori confirmed it.

"Yes. I am sure that Meng Yue is not the Seven Sins."

Shidou nodded and answered affirmatively. Although Mengyue was a person who had died once and reincarnated, Mengyue had no intention of telling others about it. The only people who knew about it were Mengyue and himself.

"Well, since Shidao thinks there is no problem, I will believe it. After all, with the help of Sister Mengyue, the chances of catching Nanashi will increase a lot."

Kotori nodded in understanding.

"I'm sorry, Sister Mengyue. I hid such an important thing from you."

"It's okay, Kotori-chan, I don't mind it."

Mengyue waved her hand to show that she didn't care. After all, after hearing the whole story, Mengyue could understand why Kotori didn't let Shidou tell everyone about it. It would be better to say that under such circumstances, Shidou still told her about it, and Mengyue was still very happy.

"So, what did Nanashi do specifically? Shidou only told me roughly that Nanashi disguised herself as everyone else and kidnapped Yui and Yoshino."

"Yeah. I understand."

Kotori nodded and explained to Mengyue in detail the various things that had happened in the past few days after receiving the letter from Nanashi.

"Hmm..." Meng Yue frowned and thought for a moment, then asked Qin Li, "At the moment, who do you think is more suspicious?"

"If there was, I wouldn't have to worry so much." Kotori shook her head with a wry smile, "If there's anything strange, it's Tobiichi Origami. Shidou disappeared before he came into contact with the other party, so he couldn't tell whether the other party was real or not.

"I think that's unlikely. After all, if Nanashi was pretending to be Origami, she wouldn't do something suspicious like that."

Shidou said from the side.

"I'm not sure, but it could be that they're taking advantage of our thoughts and deliberately setting up a cover-up."

Kotori sighed, looking distressed. It would be a bit far-fetched to say that Origami's disappearance was caused by the Seven Sins, after all, it didn't make much sense. But it happened at such a delicate time, which made people have to pay attention to it.

"Forehead……"

Hearing what Qinli said, Mengyue's forehead was slightly sweaty, and she raised her hand awkwardly and said.

"I'm sorry, Origami is missing, maybe it's my fault."

““Huh?”

With Shidou and Kotori looking puzzled, Mengyue told them about her meeting with Origami the day before yesterday and the sudden change in Origami's attitude towards her.

"This has happened before. Why is it so sudden?"

Shidou asked in confusion. Although he could understand the intention of Meng Yue's action, the timing seemed a bit sudden.

"I guess it's just a feeling or something like that. Although Origami Tobiichi seems to be no different from usual lately, I don't know why, but I have a bad feeling in my heart."

Meng Yue scratched her long hair and sighed in frustration.

In fact, Mengyue herself knew that it was a bit rash to meet Origami without explaining it to Shidou and the others. After all, Origami Tobiichi's attitude towards elves was not very friendly at the beginning, and many of her previous contacts were based on Shidou. If the elves invited Origami privately, it would be normal to be disliked.

But... Mengyue always had an inexplicable feeling of anxiety in her heart, that if she didn't keep Origami now, everything would be too late.

"Meng Yue?"

"Ah? Ah, nothing."

Meng Yue came back to her senses when she heard Shidao's voice.

[Although I am still concerned about the origami issue, the most urgent task is to solve the problem of the Seven Sins. ]

After a helpless smile in her heart, Meng Yue took a deep breath and a thoughtful look appeared in her eyes.

"Well, about origami. I'm sure it's not Nanashi in disguise. At that time, she was holding Shiori-chan's photo and licking it with an intoxicated look on her face.

I don't think Seven Sins can imitate the way he enjoys himself from the bottom of his heart."

"Um...it's true that no one except Tobiichi Origami can do such a thing."

After hearing Mengyue's description, Qinli blushed and agreed.

“But why are my photos in women’s clothing next to Origami…”

Shidou asked with a frown on his face.

"Well, this isn't the point. I have some ideas about the Seven Sins."

Mengyue waved her hand and changed the subject without making a sound, avoiding Shidou's gaze. Although Shidou was still a little concerned about what happened between Origami and Mengyue at that time, after hearing Mengyue's words, Shidou's eyes instantly became serious.

"Meng Yue, do you know who the Seven Sins are?"

"Sigh... Rather than guessing who Nanashi is, it's better to say that I have a certain understanding of this game. To be honest, if you, Shidou, hadn't confirmed that I wasn't Nanashi in disguise, I wouldn't have dared to say it casually. Let me tell you the result first..."

Putting down the pile of documents with various intelligence in her hand, Meng Yue sighed and said:

"The people Shidou investigated during the three-day date, including Kotori and me, were not disguised as Seven Sins."

"what?!"

After hearing Mengyue's unexpected words, Kotori and Shidou opened their eyes wide. After all, the people Mengyue was talking about were all the people photographed in the photos sent by Nanashi.

"Sister Mengyue, why do you think so?"

Qin Li frowned, but then quickly calmed down. She knew that Meng Yue would definitely not make arbitrary judgments, so she waited patiently for her explanation.

"The reason I made this judgment is that there are too many problems in this game." Meng Yue said seriously, "The first problem is, can the disappeared person be identified? Yui disappeared on the first day, and Nanashi appeared and asked Shidou to identify his true identity at midnight on the second day. If it can't be identified, Nanashi just needs to pretend to be Yui from the beginning. It's game over at the beginning of the game."

Hearing Mengyue's words, Qinli was stunned at first, then nodded in sudden realization.

"Indeed, Nanashi didn't say that. If someone is told to disappear, that person is Nanashi - such thoughts will disappear from our minds and we will be in an absolutely safe place. So, Yui is the most suspicious...?"

Halfway through her speech, Kotori stopped in confusion.

"It seems that you have noticed it, Qinli."

"Notice anything?"

Shidou asked somewhat confused.

Meng Yue sighed lightly and asked Shidao, "Shidao, suppose if last night when Nanashi asked you to point out, you realized on the spot that Nanashi did not point out the disappearance of the person. What would you do?"

"What to do..." After Shidou pondered for a moment, he slowly answered, "Then point to Yui? If you know the intentions of the Seven Sins, Yui is the most suspicious...?"

When he said this, Shidou showed the same subtle expression as Kotori.

"Yes, this is a hidden thing. But it's not a problem that you can't realize. Even if I don't tell you, you will notice it sooner or later. The moment you discover this, Xixian will instantly become the most suspicious object. Rather than being the safest position, it's better to say it's the most dangerous position."

Meng Yue shrugged and smiled. This is why Meng Yue chose to state the conclusion first.

"Then the second question, Nanashi also didn't explain it. How many chances did you have to point it out, Shidou?"

Picking up the envelope sent by Nanashi from the table, Mengyue took out the postcard with the criminal statement and read out the contents.

[I’m right here.]

Can you guess which one is me?

Before everyone disappears from this world,

Seven Sins

This guy Qi Zui is really good at playing word games, Meng Yue couldn't help but think in her heart.

"Until everyone disappears... From this initial message, shouldn't it be said that you can continue to point out until everyone except Nanashi disappears? In other words, if Shidou points out Yui on the next day, even if Yui is not Nanashi, you can point out Yoshino today when Yoshino disappeared. As long as Shidou lists the people who disappeared the day before every night... It's equivalent to choosing twelve out of thirteen, you will find that this completely brainless method has a more than 90% chance of making your stress of the past few days disappear completely (laughs)."

Of course, if this doesn't work, Mengyue can only say - my friend, Africa welcomes you.

"Mengyue, stop joking."

Shidou scratched his head with a wry smile. This matter concerned everyone's choice, so even if there was a 99% chance, Shidou would not dare to guess. However, he had to admit that if he thought along this line of thought, he would find that the Seven Sins were in an extremely unfair position in this game.

“Finally, this is the beginning of this postcard.”

Mengyue showed the postcard to Kotori and Shidou, pointing to the beginning of the article.

"'I am among them' - I don't think Seven Sins would have told you later: 'I am among these thirteen people'."

Kotori and Shidou both widened their eyes at the same time.

"I see... the ambiguous previews and subsequent rule additions were all designed to make us think that the Seven Sins were among the thirteen. If the answer wasn't in the options from the beginning, the Seven Sins would be invincible no matter how they answered. We were tricked."

Kotori clenched her fists slightly and shook her head in self-mockery.

"Well, actually, there is a simpler and more crude way to come to this conclusion."
