Why Not Add Me to All Those Geniuses in Omni-Anime?

Himemiya Chihaya shrugged and answered for her.

"..."

Seeing that Sakurajima Mai didn't seem to care, she nodded. "To be honest, rather than whether 'Adolescence Syndrome' really exists, I'm more inclined to think this lady is lying to you."

"..."

Meeting Sakurajima Mai's sly smile, Himemiya Chihaya relaxed her brows. She was used to it.

"Ahem~"

Sakurajima Mai suppressed a laugh and corrected, "I understand Futaba's concerns, but let me correct you first, Chihaya is actually a boy, didn't I just say 'him'?"

Huh?

Futaba Rio's eyes narrowed, and she blinked blankly as she re-examined his entire body.

From his name and appearance to his barely noticeable physique when seated, what about him resembles a boy?

"Don't feel sorry, I'm used to it."

He chuckled nonchalantly, stood up, and spun around a few times to give her a better look.

"..."

Futaba Rio, already wearing her lab coat, blushed; it was the first time she'd encountered something like this.

At first, she thought the other person was probably a friend of Sakurajima Mai in the entertainment industry, given their outstanding appearance.

Compared to him, the handsome male athletes in the sports department that the girls at school liked were like wild beasts rolling around in piles of sweat...

"Cough."

She coughed lightly to ease the awkwardness and got busy.

First, I filled a beaker with water and placed it over a lit alcohol lamp. Then, I took out a coffee can from a nearby cabinet to prepare coffee for them.

"Would coffee be alright?"

"Oh dear, this is troublesome."

"OK."

Himemiya Chihaya glanced at her phone, realizing she couldn't linger too long; she still had to go back to assist the Student Council afterwards.

"Mai, I have some things to do later, like buying cat food... I'm planning to buy groceries. Could Futaba come with me? I'll meet up with you later."

"That's possible, but you mentioned cat food, right?"

Sakurajima Mai narrowed her eyes with a terrifying expression.

"... It's your imagination."

He quickly changed the subject. "I was just thinking that if Futaba experienced it with you, she might be more likely to believe it!"

"That's true."

She nodded in agreement, "But that's a completely different matter from buying cat food."

"..."

Futaba Rio frowned as she watched the two of them face off, then suddenly spoke up, "You two have such a good relationship."

Hearing her say that, Sakurajima Mai asked for his opinion, "Really?"

Himemiya Chihaya remained noncommittal. "It's probably because Mai- san is quite kind; after all, she called me by my name as soon as we met."

"I already let you call me by my name, so we're even."

Sakurajima Mai quickly added to the comment.

Hi hi~

"... How long have you two known each other?"

"A little over a week."

"Can you get this familiar in just one week?"

"Perhaps it's because we're both rather extroverted and talkative types?"

"I can say whatever I want, but is it really appropriate for Mai- san, who has no friends, to say this?"

"Shut up."

"..."

Futaba Rio slightly opened her mouth, unsure how to join in this somewhat strange conversation, so she could only cover it up by making coffee while the water was boiling.

First, she added coffee powder to the cups with a spoon, then poured hot water for each of the three people. Finally, she took out an opaque brown bottle and handed it over.

"Add the sugar here."

"Thank you... is this sugar?"

Sakurajima Mai looked at the chemical bottle labeled "Manganese Dioxide" in her hand with suspicion.

Futaba Rio glanced at it and explained, "Because there are no other containers."

"That's true..."

She accepted it with resignation.

It's the Science Club, after all... right?

Holding her coffee cup and staring at the rising steam, Futaba Rio, trying to avoid a repeat of the earlier awkward atmosphere, offered her advice from her own perspective. "Let me state upfront that I still hold a negative view of such supernatural phenomena."

"If such a thing really happened, how would you explain it?"

The speaker was Sakurajima Mai, whose expression was unusually serious.

Futaba Rio's eyes lifted and then fell back down. "If I'm focused on something, or if I'm daydreaming, I probably won't see Sakurajima- senpai. The human brain won't look at things it doesn't want to see."

"In addition, there is an observational theory—that everything in this world exists only because it is observed."

"If we explain it using quantum physics, it means that if no one observes Sakurajima- senpai, then Sakurajima- senpai doesn't exist."

Himemiya Chihaya listened quietly, not particularly interested.

Now that things have come to this, even if you tell him that everything in the world is made up of information and matter—that's a physical thing...

If he could still deceive himself before, believing that it was merely due to quantum entanglement that his memories of a certain place and time were completely copied into this world, resulting in the so-called rebirth effect, then...

Now...

He could only admit that this might be a world like the one in A Certain A Certain Magical Index, where both scientific and fantasy laws coexist.

Even if the laws of quantum physics remain unchanged, the power of fantasy, like Adolescence Syndrome, also exists simultaneously.

Sakurajima Mai listened intently. "This is that one, right? Schrödinger's Cat?"

"That's right,"

Futaba Rio nodded affirmatively. Since the other party already knew, she was too lazy to conduct experiments and explain.

"The theory is roughly this: if you put a cat in a box containing a radioactive device and a gas canister, the device has a chance of releasing radioactive material once every hour, and the gas canister will open upon contact with the radioactive material. So, what would the cat's state be after 30 minutes?"

"Before opening the box, the cat was unaware of what was happening; therefore, the cat was in a superposition of life and death."

"So, Miss Mai is currently in a superposition of existence and non-existence."

Himemiya Chihaya teased.

"Please don't make jokes like that in front of the person involved, okay? It's really cringeworthy."

Sakurajima Mai closed her eyes and refused, like a doll.

"It's creepy, but he's right,"

Futaba Rio glanced at him. "If that really happens, Sakurajima- senpai's existence cannot be confirmed until the observer confirms it."

"So, if it's to solve a problem, why did you two come here in the first place?"

Sakurajima Mai slowly opened her eyes, looked at him, and replied, accepting the fact, "Is it because Chihaya guessed that the observer is located in the school?"

"Um?"

After a moment of confusion, Futaba Rio pointed at herself in astonishment. "Could it be me?"

He waved his hand in denial. "No, no, no, it's just that in this school, Mai is only familiar with you, so I came to check things out first, since I have absolutely no clue what to do."

"Doesn't this mean I'm the prime suspect?"

"If you insist on understanding it that way... no, it's better not to understand it that way."

He sipped the coffee he'd been blowing on; it was still quite hot, so he could only taste it first.

Then, he put down the glass, stood up, stretched, and said goodbye to the two of them, "You two can discuss the illness first, I'll be going now. I'll come to Mai Mai's house to find you later."

Why is it the prerequisite that we gather at my house?

Sakurajima Mai glared at him coldly. "What do you mean by 'illness'?"

"Because it's Adolescence Syndrome ~ Doesn't that sound like a disease name?"

"That makes me inexplicably want to punch you."

Haha... Bye-bye!

He quickly slipped to the door, opened it, rushed out, and then closed the door behind him.

Soon after, through the doors and windows, one could faintly hear shouts and commotion from outside, proving that his earlier worries were not unfounded.

"Sorry to keep you waiting! Senior Xiao Youxiao!"

With a sudden yank of the door to the Student Council Room in Hanasakigawa, Ogura Asahi rushed inside, announcing his arrival.

"Ogura-kun... you've come at the right time! Here's a pile of documents for you!"

Ichigaya Arisa, as if seeing a savior, unceremoniously pulled him to the opposite side and handed him a batch of work.

Okay, what are we going to do today?

"Let me think... Regarding the live performance, it includes the script for tomorrow's broadcast announcement, the seating arrangement for the audience on both sides of the stage, contingency plans for unexpected situations, preparations for moving musical instruments and sound equipment, arrangements for personnel to guide the junior high school student audience, the live Program List schedule..."

Ichigaya Arisa read through the general details of her discussion with Okusawa Misaki. Compared to the overwhelming workload of organizing live performances outside, this kind of rushed live performance was relatively simple and easy.

At least with school permission, new song preparation, costume arrangements, promotional posters, ticket sales, and pre-event rehearsals, etc., there's no longer any need to worry about anything else.

Even so, they still have a lot of other school work to do and don't have much time to spend on this.

"I understand. Leave all of these to me."

"Please! We'll help you after we finish the audit for the club's application!"

For an ordinary student encountering these kinds of tasks for the first time, just hearing this long list of tasks would probably make their spirits sink to the bottom, knowing that they probably wouldn't be able to go home on time today, or even finish the task...

But he was clearly an exception.

He took on all the work without a single complaint and immediately got into work mode to save time.

"Considering the teachers' time at school, let's address the staffing issue first. Arisa- senpai, please find me the teacher and student personnel list. Once it's finalized, I'll input it into the computer, print it out, and send it to the principal."

"While the playground would be ideal, since Kokoro-senpai suggested the courtyard, let's do it here; the view is better. Put up warning tape at the entrances to limit the number of people. Considering capacity, high school students are encouraged to watch from windowsills, corridors, or the rooftop. This will be mentioned in the announcement..."

"What songs will HHW and PPP perform? Misaki- senpai, Arisa- senpai? Finally, could you tell me about Eve- senpai PP's scheduled program... Scheduled entry time, start time, MC time, changing/preparing time... Schedule complete, may I borrow the computer in the student dormitory?"

"Considering potential situations, the prepared medicines and supplies, the phone numbers of the school doctor and teachers... with less than an hour left, we won't move the desks and chairs; standing room will accommodate more students..."

"For a better experience, it would be best to contact the cafeteria and ask them to set up a stall nearby to sell lunch and drinks..."

"..."

Because the most time-consuming part, setting up the venue, had been handed over to the Black-clad Legion of Tsurumaki Kokoro, he completed it very quickly, taking only half an hour to resolve all the issues.

"Is there any other work? Arisa -senpai, Misaki- senpai?"

After returning from his report outside, he asked the two girls who were still engrossed in their work.

"Huh? You've finished everything?!"

Sitting in the president's seat, Okusawa Misaki looked up and met his carefree and relaxed posture, and asked in surprise.

"Is this for real?! So fast?!"

Ichigaya Arisa was equally dumbfounded, and the pen she was holding fell limply to the ground.
