Trinity is an academy where wealthy young ladies make up the absolute majority of the students. Their beauty is so widely known across Kivotos that people say the water in the lakes surrounding the academy is so clean you could drink it straight! Essentially, it’s a school with a strong religious hue, venerating the primordial divinity, and at its heart stands the largest cathedral in Kivotos…

Walking alongside Miyako, who took it upon herself to escort him today, the teacher paused as he reflected on Arona‘s explanation, finding himself in a spot where he could see the entire cathedral all at once. Indeed, as Arona said, it seemed unlikely that a more gigantic cathedral existed anywhere else in Kivotos.

Suddenly, a familiar face caught the teacher’s eye.

“So, that must be Kirihouji Nagisa, one of the student council presidents of Trinity…”

Yet, before he could think of the council president more, it was the memory of a female student entangled in Mika’s unsavory relationships that crossed his mind. Still, out of respect for the title of student council president, he purposely shifted his thoughts that way.

But then…

“Oh? You’re here earlier than scheduled, Teacher! And Miyako! Long time no see!”

“Um…? Who are you greeting me?”

This unfamiliar girl walked right up to him and Miyako to say hello, while Nagisa glared at him coldly.

“You are… Wait a second.”

As the teacher recalled what had happened recently in Sanhaegyeong, he looked at the girl, who was at least two or three heads shorter than him, with a perplexed expression.

“Could it be Mika?”

“Huh? Are you talking about Mika-senpai? This girl here?”

“Wow—oh… Unlike Rabbit-nee, you recognized me right away, Teacher! Impressive!”

“Well, something similar happened recently. A youth rejuvenation potion, right?”

“Ahem. How have you been, Teacher? Welcome to Trinity.”

“Ah. Nagisa, good to see you. Have you been well?”

As the teacher asked Mika about the youth rejuvenation potion, Nagisa cleared her throat to greet him.

“Yes, I guess it would be correct to say I’ve been well. Teacher, although it’s a little earlier than planned… since we’ve met like this, how about you both come along with us? Of course, you can take a little more time to look around our academy before your appointment.”

Even while speaking politely with a soft tone, the teacher felt Nagisa‘s subtle hostility. He hesitated for a moment.

Had he ever crossed Nagisa‘s mood before? Was it just a coincidence that he met her while she was in a bad mood? Or perhaps…

‘No, what’s important right now isn’t that.’

It was a matter he could clarify through conversation, but he needed to answer her question more urgently.

“Let’s go together. It’s Sunday today, after all. I came early to avoid making you wait unnecessarily. We can look around Trinity after finishing work later.”

“Ahaha, sounds good! So right now—”

“But before that, I want to know how Mika became younger; I’d like to hear why too.”

“Ah, that~?”

As Mika nodded knowingly, the teacher caught Nagisa turning her gaze away, and instinctively felt that something was a bit off. He was convinced that it somehow related to Nagisa.

“I took the potion simply because I wanted to be younger! Yep. Sometimes I just want to escape from a hard daily life. Since my body is younger now, I love how the older girls treat me so carefully!”

…It seemed his assumption had missed the mark by a bit.

“Hehehe… So what do you think, Teacher? I’m probably the cutest now!”

“Mika, was this always your personality?”

“Mika is… a bit self-absorbed, to be honest. It’s understandable since she often says her face is the prettiest by her own words.”

After saying this, Nagisa cast a wary glance at the teacher, leaving him puzzled as to why.

“You’re the cutest, senpai. That rabbit headband would suit you well.”

“I see. Yeah, she is definitely cute.”

“Right, right? But I don’t really know about the rabbit headband. Oh, Teacher… Wow…?”

“Let’s go now, Teacher. Sunday is valuable for all of us, including you.”

“Ahaha, Nagisa-nee is adorable☆”

“That’s noisy, Mika. I have to correct that bad habit of yours someday…”

As Mika was led away by Nagisa, waving her hands energetically, the teacher chuckled softly and followed behind them leisurely.

In that moment, every Trinity student’s face he saw was bright, and there wasn’t a single person without a smile. As he noticed how wonderful Trinity was, he thought.

“Everyone should be a little more honest… I feel sorry that they seem to live too tiresome lives.”

“…Honest? Mika, what do you mean by that?”

“I’m talking about those kids’ smiles, Teacher. About one… third of them aren’t really smiles, you know. That’s just how the atmosphere of this school is. Beneath those smiling faces and polite manners, many kids hide their true selves.”

The maturity that did not quite match with her youthful appearance felt oddly out of place, but the teacher didn’t find it unpleasant to see this other side of Mika. In fact, it was more accurate to say he appreciated it.

The students who felt suspiciously out of place were actually kind-hearted kids, consistently proving that they cared for others. For a teacher who had become accustomed to the eccentric behavior of students in Kivotos, this was a welcome sight.

“Listen, Teacher. I find that point so frustrating. It might be a bit presumptuous of me to say that it’s wrong, but I think those kids could have a more enjoyable school life if they just acted more honestly… Yeah, something like that.”

…But why did he feel like something didn’t quite add up? The teacher couldn’t figure out the cause until they arrived at the building used by the T-party.

Following Mika and Nagisa, he found himself on a terrace on the top floor. There were several chairs placed around a tea table set up there.

“Could you prepare one more chair over there?”

“Understood, Nagisa-sama.”

Watching a servant rush off to follow Nagisa’s command, the teacher could finally grasp the previous explanation he received from Mika.

Judging by how respectfully a student from the elite T-party treated Nagisa, it was clear what status the representative of the T-party held among the upper-class students.

“…But, there are already five chairs here. Is there really a need for one more?”

“Ahaha, well… it was originally supposed to be just me, Nagisa-nee, and another sister for a talk with you. But for some reason, the representative from Gehenna—or rather, someone qualified to represent them—happens to be here at Trinity! So I reached out to them on our way here. They should arrive soon with my secretary.”

“I see. Then who is that other person…?”

“I suppose they are the student who’ll escort you during your stay in Trinity and Gehenna. Honestly, I didn’t expect to bring Miyako-nee as the escort… but, well. You’ll meet that sister soon enough. Yep.”

The teacher nodded and glanced around. The view of Trinity from up high was so stunning that it was impossible not to marvel.

“The scenery is wonderful. I might find the indoors a bit stuffy if I usually have tea in a place like this.”

“Well, that’s only half-true, Teacher. You probably know that Trinity has three representatives, so I’ll skip over that… The third student council president, Yurizono Seiya, often holds tea time here. Personally, I focus more on the people than the place…”

“People, huh…”

As the teacher motioned to Mika, she nodded in agreement.

“A comfortable atmosphere is one of the elements that lead to the most perfect tea time. It plays a huge role in bringing mental and physical stability. In my case, bringing that comfortable atmosphere… well, I would say it’s Mika-san’s presence. Fufu.”

“Really, Nagisa-nee, how can you say something like that so casually? Teacher, I usually don’t come here unless I’m meeting someone really important. I usually host guests in the indoor office unless it’s a student council president from another academy… or someone like you. Ahah, so in that sense, you might be having quite a rare experience?”

With a smile, Mika naturally took a seat, making it only fitting since she was the host of this meeting.

“Then, Teacher, before the other two arrive… I thought we could chat a bit about the Eden Treaty. You know, when, why, how, who initiated it, and what it was for… just some light, boring chat. I warned you in advance, so I hope you bear with me☆”

The conflicts between Trinity and Gehenna, along with the structure of Gehenna and Trinity. This connected to Mika’s efforts for relationship improvement between the two academies, and finally led to the events between Mika and the student council president that resulted in the Eden Treaty.

The teacher would say it was as captivating as Mika described, despite her claims about it being boring.

[…It’s a conspiracy.]

Someone’s voiceless outcry faded away without reaching anyone.
