Chapter 105 Part 2
When the math class was over and Dei-sense left the classroom, a sigh of relief escaped from the male students at once, and at the same time, several rattling sounds of chairs being pulled back echoed through the room.
If it was a popular teacher with good teaching methods, eager students would sometimes ask questions, but this was not the case with Dei-sensei at all.
When Yuu, who was invited to go to the bathroom together by Rei, got up and was about to leave the classroom, he was stopped by their homeroom teacher Kanbayashi-sensei, who popped out from the hallway.
「Hirose-kun!」
「Ah, yes」
「You see, there was a call for you. It was from a woman named Fujiki-san from the Toyota Memorial Foundation.」
「Fujiki…?」
「Do you know her?」
As there was the possibility that it was done with mischievous intent toward the male student, it was the school’s policy to always check with the male student as opposed to summoning him right then and there.
Because of his friendly personality, Kanbayashi-sensei, who was only 25 years old, was popular with the male students and was seen as an older brother figure by them.
He was also characterized by his casual manner of speaking, which was not typical of a teacher.
Retracing his memory, Yuu recalled the woman with whom he had a talk alongside Inui Rumiko, an official from the Ministry of Health, Labor and Welfare, when he underwent a special examination at the Saitama University Hospital more than 10 days ago.
His first impression of her was that she was a cool beauty, but when the conversation switched to his test results, she showed surprisingly cute and spirited sides.
「Yes, I know her. We met and talked at the hospital the other day, after all.」
「I see, good then. I have a message for you from her.」
「Message?」
As Yuu parroted the question back, Kanbayashi-sensei looked at his handwritten notes and told him…
「Err, she said: please come to the office after school. We’ve talked about it before, so if you come, you will understand.」
◇ ◇ ◇
「Truthfully speaking, we were supposed to explain it to you first-year students in the second semester, you see. You’re a special case, Hirose-kun.」
「Huh, is that so?」
Leading Yuu as she listlessly brushed her long brown hair that reached halfway down her back was a woman from the office named Gonda.
When Yuu visited the office after school, she welcomed him, and now they were walking down the hallway on the first floor of the administration building with her in the lead.
They had just passed by rooms such as the staff room, infirmary room, and career counseling room.
Because of Yuu’s presence, they ended up attracting attention from faculty members and female students when they passed by them, but Gonda deliberately paid them no mind and walked on.
Although still within school, the place they were currently headed for was located in the opposite direction of the main gate and the first ground.
From what he heard, it was a new facility called companionship hall, located in an inconspicuous location in the back.
This was also the place that was omitted when Yuu and the others toured the school shortly after they enrolled into the school.
Since a while ago, Yuu had been looking at Gonda’s back as she walked in front of him.
She was about 5cm taller than Yuu and slender, and what she was wearing was probably the office uniform.
Pink blouse and navy-blue vest. On the bottom was a tight skirt of the same navy-blue color with its hem slightly above the knees.
His eyes couldn’t help but get drawn toward her bouncy buttocks and long, slender, beautiful legs.
It was said that there were many men who liked seeing women in uniforms.
Yuu also liked high school girls’ uniforms, including Sairyou Academy’s sailor uniform, which he often saw, and when he was in the hospital, he feasted his eyes on the nurse’s white coat (pink was also acceptable).
However, when he was an office worker, the uniform of an office lady was one thing that stirred his manly instincts.
The form-fitting uniform showed off the woman’s figure vividly.
In particular, for men, their eyes would inevitably get drawn toward their buttocks and legs.
Yuu never did (couldn’t do) such a thing, but it wasn’t like he couldn’t relate to the old men who would want to sexually harass a young, attractive office lady right when they saw one right in front of them in the office.
If it were the current Yuu, if he casually touched them, let alone getting angry, perhaps they would be delighted by it.
However, having just met, Gonda’s attitude was somewhat curt, so he refrained from suddenly intruding upon her private space.
Perhaps she dyed her straight brown hair. Her bangs, which appeared to have been curled with curlers, were long enough to cover her eyes.
Her makeup was on the heavy side, but she didn’t seem to be that old. She was probably just over 20 years old.
Coupled with her coarse way of speaking, she gave off the impression of a former delinquent.
Her eyes were slanted and were a little sharp, but her facial features were by no means bad, so he got the feeling that she would be more popular with men if she wore less makeup.
While Yuu was thinking about such a thing, the two of them exited the back door of the administration building and passed through the connecting passageway.
The second ground could be seen on the left.
The football club was already practicing there.
Speaking of the football club, Sati and Kayo, with whom he had flirted in the music preparation room during the second period break the other day, should be there too, but not only did they have a large number of members, they were far away, so he couldn’t find them.
「It’s here」
「Ah, yes」
The building in front of them was a small, two-story building with a cream-colored exterior.
From the outside, it was about half the size of the administration building they passed through earlier, so for a school facility, it was on the smaller side.
Gonda walked toward the nearest entrance without hesitation.
As they opened the glass door with a rattle and stepped into the building, they saw a modest signboard overhead that read 『Private Sairyou Academy High School – Companionship Hall』.
Immediately after entering, the reception counter could be found on the right, where a female clerk was sitting.
Gonda seemed to be acquainted with her, so she casually approached her and called out to her.
「Thank you for your hard work!」
「Hello. Are you applying for use?」
「We’re here for the matter I told you about by phone at noon.」
「Ahh!」
It seemed that she had already told her about it, and when Yuu showed the clerk his student notebook as prompted, she said 「Are you sure?」 and showed him the blank form she had in her hand.
The message from Fujiki from the Toyota Sakuya Memorial Foundation said nothing but 「We have arranged a partner for the matter we talked about the other day」. Most likely, they want me to meet my elder sister from a different mother; so he thought.
When Yuu nodded his head, the clerk simply wrote something on the form and stamped it, and the procedure seemed to be completed.
Suddenly turning to the side, Yuu noticed that there were 10 lamps lined up at the top of the wall, with 1 and 3 lit.
「Please use room 3. Yes.」
「Aight.」
「Now then, Hirose-kun, I’ll explain as we walk, so please come this way.」
Tearing off the bottom of the application form, Gonda handed it to Yuu, then proceeded to the back of the room.
Yuu followed her, looking around with a curious look on face.
The inside of the building resembled the administration building, but the glass windows were covered with cloth, so it was not possible to see what was going on inside.
「This Companionship Hall is a facility that was built not long after we became a co-educational school. We hold various classes and practical training here with the aim of understanding the differences between men and women and deepening our friendships. First-year students will attend one hour of it a week starting in the second semester. Starting from second year students, not only will you have to attend two hours of it per week, we will invite external instructors and have you conduct some special training with them.」
He felt that her explanation was unusually smooth, but when he looked at her, he noticed that she looked at the cheat sheet she had in her hand from time to time.
In short, it seemed to be a more advanced version of health and physical education.
In this world, men and women were raised as far apart as possible.
Especially in middle school, when they reached adolescence, they spent their time completely separately.
If such boys and girls were suddenly made to interact with each other in a co-ed school, there was no way things would go well.
As such, under the leadership of the student council, they held boys-girls social events once a month, which were more of a fun event than a support event.
The basic idea was probably to let them learn about the reality of the opposite sex and learn how to date through classes and practical training at the Companionship Hall.
「Excuse me. What do you mean by practical training?」
「Err… Umm, in short… like directly looking at or touching a naked member of the opposite sex.」
「Huh!?」
When Yuu about the point he was curious about, Gonda clammed up and hesitated for a moment before answering.
Moreover, it was quite the surprising one.
In front of an entire class of male students, an adult woman – sometimes they called in a professional model, sometimes a young faculty member put up her body – stripped completely naked and let them touch her however they pleased to learn how the opposite sex’s body worked.
From Yuu’s point of view, it was like the world of AV or erotic games.
Did that mean…?
「Do boys get naked in girls’ classes?」
「No, that’s…」
Gonda smiled bitterly.
「Paying quite a lot of money, we invite men who work in the sex industry, so we can only do it once a year at most. Usually, you only learn from videos. There’s nothing we can do about it, so we ask some girls to play the roles of boys and have them learn how to date.」
「Hahaa」
At that time, I don’t mind serving as the model.
Being naked in front of 30 or so high school girls, that sounds pretty exciting.
So Yuu thought on the inside, but he kept it to himself for now.
When they reached the stairs, Gonda proceeded and climbed it down.
Apparently, their business was underground.
In an easily visible place on the wall, there was a sign with an arrow pointing to 『Special Male-Female Communication Room』.
What on earth is it for?
At the end of the stairs was a straight hallway with five numbered private rooms on each side.
The numbers ranged from 1 to 10.
Suddenly, when Yuu looked down at the piece of paper that had been handed to him earlier, he noticed that today’s date, reception time, and room number 3 were written on it.
Yuu’s name was written in the user column, and First year was written next to it in parentheses.
Next to it was a name he was unfamiliar with, 『Takahata Kiyoko』, and in parentheses was School Clerk (28).
