This is not the date I wanted.

Kotori sighed helplessly and asked Shidou.

"Well, that. You see, Mengyue has such an obvious personality contrast, and Tohka also said, 'Although it feels like Mengyue, it is different from Mengyue', so I wonder if this is a second personality or something like that."

Kotori raised the corner of her mouth and looked at Shidou with some surprise.

"I have come to this conclusion after careful consideration. To be honest, I thought you were recalling the time when you fell into a deep sleep during class in junior high school and fought against the other dark Shidou in your heart..."

“Ah, ha, haha ​​...! You, you are so annoying, little sister. W-what are you talking about? I, I, I, I, I don’t understand anything you say!”

Shidou looked up at the ceiling and laughed dryly, sweat began to appear on his forehead.

Looking at Shidou's poor acting, Kotori shrugged helplessly and turned to ask Reine beside her.

"Reine, do you think Shidou's conjecture is possible?"

After hearing the order from her superior, the insomniac who was trying to stand unsteadily tilted her head and remained silent for a moment before answering.

"Well... Although according to the current medical and psychological theories on the causes of split personality... the possibility of Meng Yue having this situation is very low. But considering that there may be something about the elves that we still don't understand... from the current lack of information, guessing is probably the most likely option."

Although Shidou wanted to complain about how Reine, as a battleship analyst, could know such a rare knowledge as split personality, Kotori didn't care about it and nodded thoughtfully after hearing Reine's words.

"Well... let's just take Shidao's guess as a thought. Assuming Shidao's guess is correct, the current Mengyue Sister is not the Mengyue Sister we know. Then the next question is, how much does she know about the current situation? What is her attitude towards the original Mengyue Sister? What is Mengyue Sister's current state... We must understand these clearly."

Faced with these continuous questions, Qinli rubbed her temples with a headache.

"Where is Sister Mengyue now?"

"Well... I was just chatting with the elves. A few minutes ago, I said I had to finish the game in the morning, so I went back to the elf apartment."

"Hmph~ Then please, Onii-chan."

Kotori picked up a particularly good one and put it in her mouth, crossing her legs.

"what?"

Shidou asked, feeling a little uneasy.

"Need I say more? The next task, of course, is for Shidao to work hard to improve the favorability of the other Mengyue sister, so as to ask her for various information. Only in this way can we make a good plan for the next step."

"So the specific means..."

"It's a date, of course."

really……

"Whoo~"

Just like that, Shidou stood in the corridor of the Elf Apartment, facing the door of Mengyue's room. He took a long, deep breath to relieve his tension, and knocked on the door gently.

"Meng Yue. It's me, Gokawa Shidao. I have something to tell you. Can you open the door?"

"........."

There was no response from inside the door.

"not here?"

Shidou thought with some confusion.

[It shouldn't be. The camera didn't capture Sister Meng Yue leaving the Elf Apartment. Either she was too absorbed in the game to hear it, or she was too lazy to respond to Shidao's meaningless knocking, which sounded like the kind of uncle who had been corrupted by society.]

Kotori complained in the headphones.

I was just being a little polite, is it necessary to belittle him to this extent? Just when Shidao was thinking about this with some laughter and tears, Kotori suddenly said with some surprise.

[Ah, wait, Shidou, the options are out. ]

Based on the analysis of the plot development and the situation, Fraxinus's artificial intelligence provides Shidao with three options for action to take.

"It feels like I haven't been here for a while... Based on the situation, I should ask Mengyue to come out."

Shidao sighed as he felt an inexplicable sense of nostalgia.

① Take off all your clothes (you can leave your panties on) and lie down in the corridor, imitating the screams of a pig being tortured ten times.

②Ha shouted and used his special move that had been sealed for many years - instant flash blast, and forced his way in.

③ She imitated the posture of London Bridge at the door, straightened her waist and panted "up~down~!up~down~!up~down~!", making Mengyue laugh and leading her out.

"..."

Shidou rubbed his eyes and confirmed the content again (Author: "Don't ask me why I rubbed my eyes after listening to the options.").

① Take off all your clothes (you can leave your panties on) and lie down in the corridor, imitating the screams of a pig being tortured ten times.

②Ha shouted and used his special move that had been sealed for many years - instant flash blast, and forced his way in.

③ She imitated the posture of London Bridge at the door, straightened her waist and panted "up~down~!up~down~!up~down~!", making Mengyue laugh and leading her out.

Shidou felt as if his heart was soaked in the Arctic Ocean. No matter which option he chose, he didn't want to choose it at all ahhhhh (╯‵□′)╯︵┻━┻

"What kind of logical analysis does AI use to provide such an option..."

At this time, Kotori in the captain's room was also looking at the options on the screen with a twitching mouth. To be honest, these options felt more like playing with Shidou than helping him.

However, since it is a conclusion reached by AI after analysis, there must be a reason for it, although Kotori does not understand it.

"Everyone, make your choice within five seconds."

"..."

The cadres in Fraxinus hesitated for a moment before slowly making their choice.

The number of people in ② and ③ is the same, and there is only one person in ①.

"Why? Why don't you adopt such a wonderful idea of ​​standing naked at the gate of a beautiful girl and screaming like a pig, and then being looked at by the beautiful girl with perverted eyes?"

Okay, ignoring Kannazuki's barking over there, Kotori sighed helplessly and pressed the call button to answer.

"Well...if I saw Shidou lying naked in the corridor and squealing like a pig, I would definitely call the police without hesitation. Shidou, choose between ② and ③."

"Can I choose neither of them..."

Shidou couldn't help but whine.

Although it is a good thing to avoid the first worst option, the remaining two options are also very challenging to one's thickness of skin.

Although the second one seems to be the most normal...

【Power is constantly pouring out of my body... Ahahahaha! No one can stop me now. Do you think that Pluto's Wall of Sighs can stop me from moving forward? Foolish elf! Watch out! Super Secret Technique—Instant Flash Explosion!!! !!!!!! !!!!!! !!!!!! !!!!!! !!!!!! 】

“Nooooooooooooooooooooooooooooooooooooo!”

Just trying to imagine it, the shame came over him like a tidal wave, causing Shidou to roll over on the spot with his head covered.

[What a willful brother... If you don't want ① or ②, then choose ③. ]

Kotori's helpless voice sounded in his ears. To be honest, even if Shidou wanted to, he couldn't really use the so-called super secret move, let alone break into the door. In fact, the only option he could choose was ③.

no solution anymore……

"Mengyue, I'm going to show you an impromptu joke, come out and see it!"

Taking a deep breath, Shidao's eyes flashed with the intention of breaking the cauldron and sinking the boat.

With legs slightly apart and lower body planted on the ground, the upper body falls backwards with gravity. Then, with arms supporting the ground, using the limbs as support and belly facing the sky, the body performs a bridge-building movement.

Then, start to shake your waist up and down.

"London Bridge in action. Up~down~!up~down~!up~down~!"

It feels like... something important is being lost.

[Pfft... No, Shidou... You are poisonous. 】

From the other end of the headset, Kotori's voice was stuttering as if she was trying to suppress her laughter, and there was a fierce slapping of the table. And this voice... seemed to be more than one.

"...up~down~!up~down~!up~down~!"

For the sake of his own mental health, Shidao decided to block his hearing. He learned the great spiritual victory method of Ah Q from the Celestial Empire - self-deception (?). Then he kept praying in his heart -

Lord Mengyue, please open the door quickly and come out QAQ.

"Pfft! Shidou-kun, what on earth are you doing with that cheerful posture?"

As if responding to Shidou's inner plea, Misaka Mimu slowly walked up the stairs, and couldn't help but chuckle when she saw Shidou's posture.

[Shidao, be happy. Mengyue's favorability towards you has increased a lot. ]

"Ha ha……"

Shidou turned over and smiled reluctantly. Although he felt that he had lost a lot of important things as a human being, he finally let Mengyue come up from downstairs.

...Wait, coming up from downstairs?

"Meng Yue... didn't you tell Yakuya and the others that you were going back to your room to play games?"

"Well, I suddenly felt a little hungry so I went down to the living room to find something to eat."

Saying that, Mei Meng shook the apple in her hand and took a bite in front of Shidou.

...In other words, under the gaze of his sister, Fraxinus and others, he made a very stupid joke in front of the door of an empty room.

"? Why did Shidou suddenly turn pale and stick to the wall?"

Mei Meng asked with a strange look on her face.

"Leave me alone...I want some peace and quiet."

Well, Kotori would never allow him to be depressed and self-isolating. Under Kotori's dissatisfied urging, Shidou could only feel sad for a while in his heart, and after trying to erase the memory just now with self-suggestion, he said to Meimeng with a serious face.

"Mengyue, I..."

"Hey! First of all, I have something to correct."

Mimu shrugged, then pointed at the tip of Shidou's nose and said seriously, "My name is Mimu, Misaka Mimu. Please don't confuse me with the other me."

Hearing Mei Meng's words, Shidou widened his eyes in surprise.

"Shidou's guess seems to be the correct answer..." Kotori said to the person who pressed the call button with a serious look in her eyes, "Shidou, ask about Mengyue's current situation. Be careful not to anger Mengyue."

"Yeah... I see. Beautiful Dream." Shidou nodded slightly, then asked with some concern, "Then, your other personality... is Meng Yue. You should know, how is she now?"

"Split personality... Thinking this way saves me the trouble of talking nonsense."

Meimeng muttered a few words to herself. Shidao didn't hear it clearly because her voice was too loud. However, Meimeng continued speaking soon.

"Well, I personally don't know the specific situation of the other me... Although I think he is alive... However, I can't be sure whether he is in danger or not."

After all, the danger level of the Magical Index world is much higher than that of dating. It is not surprising that a world crisis occurs every day.

"What!?" Shidou's eyes widened slightly, and he grabbed Meimeng's shoulders with a terrifying expression on his face, "What happened to Mengyue!?"

[Shidao! Calm down, Meimeng's mood is getting extremely bad! ]

After hearing what Kotori said, Shidou suddenly came back to his senses and realized that he was holding the other person's shoulders tightly, so he quickly let go.

"I'm so sorry! Are you okay?"

"Don't worry, don't worry~ It's a million years too early for Shidou to hurt me with his strength." Waving her hand to show that she didn't care, Meimeng chuckled and said, "Surprisingly, you still care about another me."

"...Mengyue is an important family member of mine. So I don't want anything to happen to her." Shidou clenched his fists and said seriously.

"Hou~ Well, even though I said that, since it's another me, it shouldn't be a big problem. And this is just a special episode, there's no danger of the world being destroyed or anything like that."

"I feel like you just said something really extraordinary very easily..."

"Don't worry about the small details~"

“Is this a small detail?!”

Mei Meng snorted softly, and an interested expression appeared on her face. After a brief silence, the corners of her mouth slightly raised, revealing a noble and gentle smile like that of a noble lady.

However, for some reason, Shidou felt a chill down his spine.

"Hey~ Shidou-kun~ do you want to go on a date with me?"

"Eh?"

……

"Hey! Shidou-kun! This is the starting point of our date!"

Standing on the rooftop of a large hotel that was nearly hundreds of meters high, stepping on the edge of the roof, Mei Meng was as steady as a rock in the strong wind, gazing at the panoramic view of Tengu City from afar, and showing a bright smile to Gokawa Shidao who had a green face beside him.

"No matter how others see it, it's the end of life!"

"Ah~ That's annoying. Being misunderstood as committing suicide with Shidou will become a stain on my life."
