Science-types Fell in Love,
So They Tried Giving Presentations.
**[01:36] Kanade**
It's beautiful, isn't it?
**[01:37] Himuro**
It really is lovely.
**[01:39] Himuro**
I'm sure the beauty index
here is firmly over 90.
**[01:43] Kanade**
We're staying in such a nice hotel!
**[01:46] Himuro**
Yes. We should be grateful
to Yamamoto-senpai.
**[01:50] Kanade**
Oh! The bathroom is pretty, too!
**[01:55] Himuro**
*In a place as beautiful as this...*
**[01:57] Himuro**
* If I were able to have close*
* contact with Yukimura-kun...*
**[02:00] Himuro**
*Yukimura-kun...*
**[02:03] Himuro**
*No, no, no.*
**[02:04] Himuro**
* No matter how you look at it,*
* it's still much too soon for—*
**[02:08] Himuro**
Coming!
**[02:11] Yukimura**
I'll be imposing on your hospitality.
**[02:13] Himuro**
Yukimura-kun...
**[02:14] Himuro**
It's late... Why...?
**[02:16] Yukimura**
You must know, Himuro.
**[02:18] Yukimura**
What we were unable to achieve this afternoon...
**[02:21] Yukimura**
We have to do it now.
**[02:22] Yukimura**
I'm coming in.
**[02:23] Himuro**
*Wait, wait, wait...*
**[02:25] Himuro**
*Really? Here?*
**[02:27] Himuro**
*I'm not emotionally prepared yet...*
**[02:29] Himuro**
Huh?
**[02:30] Yukimura**
No!
**[02:31] Yukimura**
How many times must I say
it before you understand?
**[02:33] Yukimura**
You need to pause for 2.42 seconds there!
**[02:36] Kanade**
When I get nervous, I start talking faster!
**[02:39] Yukimura**
Do you think you'll be able to make it
through the presentations like that?
**[02:43] Yukimura**
Now. Again!
**[02:45] Kanade (background)**
And anyway!
**[02:45] Himuro**
*I get it.*
**[02:46] Kanade (background)**
Is there really a need to accurately
measure the pause to the decimal point?
**[02:47] Himuro**
*Kanade-chan has her presentation tomorrow.*
**[02:48] Yukimura (background)**
What?
**[02:49] Yukimura (background)**
Anything less is unacceptable. Try it again!
**[02:49] Himuro**
*But our experiment is...*
***SIGN*** Times you want to snuggle close +1
***SIGN*** Times you want to hug +!
**[02:54] Himuro**
*I want to touch you...*
**[02:56] Himuro**
*I want to dive into your arms.*
**[03:00] Himuro**
*But I can't...*
**[03:01] Himuro**
*even though you're so close...*
**[03:04] Himuro**
*To think it hurts this much...*
**[03:06] Himuro**
*Could it be that this is...*
**[03:08] Himuro**
*what is called "love"?*

**[03:31] Himuro**
*At that time,*
**[03:32] Himuro**

**[03:37] Himuro**
*Which means that this...*

**[03:41] Himuro**

**[03:44] Himuro**

**[03:48] Himuro**
* It's the state in which being*
* told not to do something,*
**[03:51] Himuro**
*makes you want to do it even more.*
**[03:53] Himuro**
*For any human, it is a natural impulse.*
**[03:56] Himuro**
*Which means...*
**[03:58] Himuro**
* My desire to nuzzle my forehead*
* into Yukimura-kun's chest,*
**[04:02] Himuro**
*is not, necessarily, because I love him.*
**[04:04] Himuro**
*I nearly based my decision on supposition.*
**[04:08] Himuro**
* That would make me a failure*

**[04:10] Himuro**
* When these presentations come to*
* an end, we will have free time.*
**[04:14] Himuro**
* We will have plenty of opportunities*
* for physical contact.*
**[04:17] Himuro**
*I just have to hold on until then.*
**[04:19] Himuro**
* Right now, the first thing I need to do is*
* watch over the underclassmen's presentations.*
**[04:21] Kanade**
We came all the way to Okinawa
and we're stuck here.
**[04:24] Kanade**
Um... Himuro-senpai...
**[04:26] Kanade**
D-Do I have to present in
front of all these people?
**[04:30] Kanade**
I'm really not good at talking
in front of big crowds...
**[04:37] Kanou**
Today, we have a total of seven
people presenting, I see.
**[04:40] Kanou**
Now, if the first person
would like to proceed...
**[04:45] Kanade**
Huh?
**[04:46] Himuro**
Kanade-chan, isn't that...
**[04:48] Kanade**
He's someone who talked to us
on the beach yesterday, right?
**[04:52] Kanade**
So he's here for the lab training camp, too...

**[04:56] Shikijou**
So...
**[04:57] Shikijou**
"Seeking Nash Equilibrium in Non-Cooperative
Games Comprised of Large Numbers of People
**[05:02] Shikijou**
Through Implementation of Tabu Search Principles"...
**[05:03] Shikijou**
is the title.
**[05:05] Shikijou**
I'm from the Tokyo University
of Science and Technology.
**[05:06] Shikijou**
My name is Shikijou Naoya,
and I'll be giving this presentation.
**[05:08] Kanade**
*Yikes! I don't even understand the title!*
**[05:12] Shikijou**
First, I'll start by explaining
Nash equilibrium.
**[05:16] Shikijou**
When the number of players in
a non-cooperative game is n,
**[05:19] Shikijou**
we will call player 1's strategy P.
**[05:22] Shikijou**
At this point, there are many
ways to construct strategy P.
**[05:26] Shikijou**
The probability of any
given action is p1, p2...
***SIGN*** Nash Equilibrium
***SIGN*** When the number of players in a non-cooperative game is n,
***SIGN*** Player 1's strategy (probability distribution) p
***SIGN*** Player 2's strategy (probability distribution) q
**[05:31] Shikijou**
continuing to pm.
**[05:33] Shikijou (background)**
The value of p1 is greater than 0,
**[05:33] Kanade**
Wh-Wh-What do I do? I have no
idea what he's talking about!
**[05:34] Shikijou (background)**
and adding all values from
p1 through pm equals 1.
**[05:37] Kanade**
Himuro-senpai, do you understand this?
**[05:38] Shikijou (background)**
In the same way, let us consider
player 2's strategy q.
**[05:40] Himuro**
I understand the gist. But this is...
**[05:43] Shikijou**
With strategy q—
**[05:43] Kaku**
Excuse me.
**[05:44] Kaku**
May I ask a question?
**[05:46] Shikijou**
Oh... Please do.
**[05:48] Kaku**
It's about using a tabu search when what
you're looking for is Nash equilibrium...
**[05:54] Kaku**
The tabu search is a commonly
used method, correct?
**[05:56] Kaku**
Was there no similar research?
**[06:00] Shikijou**
Um, probably...
**[06:02] Shikijou**
Yes. With regards to games with
large numbers of players.
**[06:06] Kaku**
Then, why choose to go with a tabu search?
**[06:09] Shikijou**
What? That's...
**[06:12] Kaku**
There are many instances where
multiple Nash equilibriums exist.
**[06:15] Kaku**
A genetic search type algorithm,
which can run simultaneous searches,
**[06:18] Kaku**
would seem to be more effective here.
**[06:20] Kaku**
What merit does a tabu search present?
**[06:24] Shikijou**
Well... it's...
**[06:30] Kanade**
*I can't understand any of this conversation.*
**[06:33] Ikeda**
May I ask a question, too?
**[06:36] Shikijou**
Yes.
**[06:36] Ikeda**
I'm not familiar with this field, so I
apologize for asking a layman's question.
**[06:42] Ikeda**
In what way does seeking Nash
equilibrium prove useful?
**[06:54] Kanou**
Shikijou-kun.
**[06:56] Kanou**
If you can't answer, then you must
clearly say that you don't know.

**[07:01] Kanou**
Consuming time with your
silence is despicable.
**[07:05] Shikijou**
I'm sorry. I don't know.
**[07:08] Kanou**
I did say, didn't I?
**[07:11] Kanou**
That you should investigate and become
familiar with the points just raised...
**[07:16] Kanou**
That if you didn't understand,
you should come ask me...
**[07:19] Kanou**
That you should understand and
prepare before presenting...
**[07:22] Kanou**
You have been negligent.
**[07:26] Kanou**
What have you been researching?
For what purpose?
**[07:30] Kanou**
If you can't even explain
that basic essence,
**[07:33] Kanou**
then you have been entirely
too lax in your studies.
**[07:37] Kanou**
It is disrespectful to those
here in attendance.
**[07:40] Kanou**
We'll call this an end to your presentation.
**[07:44] Inukai**
That's terrifying!
**[07:46] Inukai**
They punch you that full
of holes at presentations?
**[07:49] Ibarada**
Well, when you're not prepared,
that kind of stuff happens.
**[07:53] Himuro**
Don't worry, Kanade-chan.
**[07:55] Himuro**
You practiced a lot yesterday, right?
**[07:58] Kanade**
But...
**[08:02] Kanou**
Now, the next presenter, Inukai Kosuke-kun.
If you would, please.
**[08:11] Inukai**
Now that it's come to this...
**[08:13] Inukai**
I've just gotta go for it!
**[08:20] Inukai**
*The man's man, Inukai Kosuke...*
**[08:22] Inukai**
*is gonna blast his way right through this!*

"Romance Visual Novel Games

**[08:43] Inukai**
So, that being that...
***SIGN*** Sure

When you pick something that
makes Aika happy, like this...

***SIGN*** Start
***SIGN*** Goal
***SIGN*** Critical Path Problem
**[09:07] Inukai**
this game is the same as what's
known as a "longest path problem."
**[09:12] Inukai**
This type of problem has
been proven to be NP-hard.
***SIGN*** ① Longest Path Problems
**[09:18] Rikekuma**
Longest path problems!
**[09:20] Rikekuma**
...but before that...
***SIGN*** ② Shortest Path Problems
**[09:21] Rikekuma**
Shortest path problems!
***SIGN*** Tokyo
***SIGN*** Akabane
**[09:23] Rikekuma**
It's a problem where you calculate the
shortest path from start to goal, bear.
**[09:28] Rikekuma**
See? It's like that thing you stupid humans
use on the Internet all the time, bear
**[09:33] Rikekuma**
It's super easy for a computer, bear.
**[09:37] Rikekuma**
Then, what if, instead, you
looked for the longest route?
***SIGN*** Tokyo
***SIGN*** Akabane
**[09:41] Rikekuma**
That's right. This is a
longest path problem.
**[09:44] Rikekuma**
It's a super hard problem that
even baffles computers, bear.
**[09:48] Rikekuma**
Just like the traveling salesman
problem, people call this NP-hard.
**[09:53] Rikekuma**
It's a crazy problem, bear!
**[09:55] Inukai**
That's right.
**[09:56] Inukai**
Adult games are NP-hard.
**[09:58] Inukai**
Finding the approximate solution
should be our next challenge!
**[10:02] Student A**
This guy's amazing!
**[10:04] Student B**
He's seriously researching adult games...
**[10:06] Student C**
He's a hero, in so many different ways...
**[10:08] Kaku**
Excuse me.
**[10:09] Kaku**
May I ask a question?
**[10:12] Inukai**
Please do.
**[10:15] Kaku**
I am not familiar with this field,
**[10:18] Kaku**
so I apologize if this is a
layman's question, but...
**[10:21] Kaku**
in what way does this research
possibly prove useful?
**[10:25] Inukai**
It's super useful for me!
**[10:28] Inukai**
If I could find an effective way to
quickly complete any romance game,
**[10:31] Inukai**
nothing could possibly make me any happier!
**[10:35] Kaku**
There's no point if it only
is of use to you, is there?
**[10:38] Kaku**
Shouldn't you do some more serious research?
**[10:40] Inukai**
What?
**[10:41] Inukai**
I'm super serious about this.
**[10:44] Inukai**
What is it you don't like about it?
**[10:46] Kaku**
I am saying that researching
romance games is not useful.
**[10:51] Kaku**
Are you listening? We are in engineering.
**[10:54] Kaku**
The foundational ideal of engineering is
**[10:56] Kaku**
to develop effective technology
for the sake of humanity.
**[10:59] Kaku**
That is the greatest difference between
this and the natural sciences.
**[11:02] Kaku**
That is why our research must, in the end,
**[11:06] Kaku**
be something which contributes to society.
**[11:09] Inukai**
Huh?
**[11:10] Ikeda**
Um, excuse me... Professor Kaku.
**[11:12] Ikeda**
This research theme was
one I suggested to him...
**[11:16] Inukai**
Games are useful!
**[11:20] Inukai**
They are fun! They are emotionally moving!
**[11:23] Inukai**
They are a contemporary
form of entertainment!
**[11:25] Inukai**
For me, they're what I live for!
**[11:28] Inukai**
Pretty much every student in
here has played a game, right?
**[11:32] Inukai**
And there's gotta be some
adult gamers here, too!
**[11:36] Inukai**
It's technology which has
entertained all these people!
**[11:41] Kaku**
Your research has nothing to
do with the creation of games.
**[11:46] Kaku**
You're simply looking for a methodology
which facilitates easier gameplay, right?
**[11:49] Inukai**
That's right!
**[11:51] Inukai**
Lately, pro gamers have emerged...
**[11:54] Inukai**
e-sports are international competitions...
**[11:56] Inukai**
This is an age where play-by-play
gamers hold live events at Budoukan!
**[12:01] Inukai**
Even those who are on the
consumer side of games,
**[12:03] Inukai**
depending on how they play,
can find all kinds of value in them.
**[12:05] Inukai**
That's the age we live in.
**[12:07] Inukai**
And I believe that one day...
**[12:08] Inukai**
my research will be useful to someone!
**[12:12] Inukai**
Not to mention,
**[12:14] Inukai**
looking down on adult games like
that is unforgivable, baldy!
**[12:17] Kaku**
Baldy?
**[12:18] Kaku**
You! Take more care with your words.
**[12:22] Ibarada**
Not bad, Torasuke.
**[12:25] Kanou**
We will now take a ten minute break.
**[12:27] Kanou**
If the next presenter would please set up.
**[12:31] Yukimura**
Right. Now, if we connect this
computer, the output should...
**[12:36] Yukimura**
Hm?
**[12:38] Yukimura**
What's wrong, Kanade?
**[12:39] Kanade**
Yukimura-senpai... I...
**[12:42] Kanade**
I don't feel like I can do this.
**[12:45] Kanade**
That research seemed super complicated
and it wasn't good enough.
**[12:49] Kanade**
Compared to that, my research
isn't anywhere near...
**[12:52] Yukimura**
You're worrying too much.
**[12:55] Yukimura**
Your presentation will be—
**[12:56] Kanade**
I can't.
**[12:57] Kanade**
It's not good enough.
**[12:58] Kanade**
Presenting in front of all
those people... I can't...
**[13:01] Yukimura**
Calm down a little, Kanade.
**[13:01] Kanade (background)**
I can't present...
**[13:04] Kanade**
What do I do if I mess up?
**[13:05] Kanade**
If everyone thinks I'm weird...
**[13:08] Kanade**
I can't take any more of that...
**[13:09] Yukimura**
Hey, Kanade!
**[13:11] Kanou**
It's just about time to
start the presentations.
**[13:15] Ibarada**
Next is Kanade, huh?
**[13:17] Ibarada**
She seemed pretty freaked out back
there. You think she's okay?
**[13:21] Himuro**
I'll go see how she's doing.
**[13:26] Himuro**
* I'm not worried about*
* Kanade-chan's presentation.*
**[13:30] Himuro**
* That Yukimura-kun drilled*
* her pretty hard, after all.*
**[13:34] Himuro**
*Yukimura-kun...*
**[13:38] Himuro**
*Oh, honestly!*
**[13:39] Himuro**
*A little more self-control, please.*
**[13:42] Himuro**
*Once the presentations are over,*
**[13:43] Himuro**
* I can have lots of physical contact*
* with Yukimura-kun. All right?*
**[13:48] Himuro**
*With Yukimura-kun...*
**[13:51] Yukimura**
Hey.
**[13:52] Yukimura**
Pull yourself together, Kanade!
**[13:53] Kanade**
I can't... I can't...
**[13:55] Kanade (background)**
I can't present in front
of all those people...
**[13:56] Yukimura**
You're leaving me no choice...
**[13:57] Kanade (background)**
If I try, I'll only fail...
**[13:59] Himuro**
Kanade-chan. Yukimura-ku—
***SIGN*** Science Fell in Love,
So I Tried to Prove It
**[14:22] Kanade**
Wh-Wh-What are you doing?
**[14:26] Yukimura**
And you, don't suddenly unleash
the force of your fists...
**[14:30] Yukimura**
It was an experiment run by Leslie Seltzer
of the University of Wisconsin-Madison.
**[14:33] Kanade**
Huh?
**[14:34] Yukimura**
Sixty-one girls aged 7 to 12 were made to
give a speech in front of a large crowd.
**[14:40] Yukimura**
Afterwards, their mothers embraced them,
**[14:43] Yukimura**
comforting them through physical contact.
**[14:46] Yukimura**
As a result, their oxytocin
levels increased,
***SIGN*** Direct Contact with Mother
Phone Call with Mother (no contact)
Nothing Done
**[14:49] Yukimura**
and their stress hormone, cortisol,
dropped significantly.
**[14:54] Yukimura**
I simply emulated the experiment.
**[14:56] Kanade**
I-I see...
**[14:59] Kanade**
Wait!
**[15:00] Kanade**
That worked when their mothers did it!
**[15:02] Kanade**
Would you really suddenly hug an
underclassman girl like that usually?
**[15:05] Yukimura**
There wasn't anyone else here!
I had no choice!
**[15:08] Yukimura**
And it's your fault for being
so extraordinarily frightened!
**[15:11] Kanade**
Why are you putting it like that?
I'll report you to the police!
**[15:14] Kanade**
Not to mention, what were you planning
to do if Himuro-senpai saw you doing this?
**[15:20] Yukimura**
That would be... terrible, but...
**[15:23] Yukimura**
That has nothing to do with this, does it?
**[15:26] Kanade**
Yes, it does!
**[15:28] Kanou**
Excuse me... If you could
start your presentation...
**[15:31] Kanade**
Oh! Yes! I'll be right there!
**[15:33] Kanade**
Oh, for crying out loud.
**[15:35] Kanade**
All that nervous tension disappeared.
**[15:38] Yukimura**
If you can make such a fuss about it,
I doubt you'll have any problems.
**[15:47] Kanade**
That senpai really has a sharp tongue,
and he has no tact at all...
**[15:51] Kanade**
and he's unreasonable in
everything he does...
**[15:55] (Flashback) Yukimura**
Wear this.
**[15:56] (Flashback) Yukimura**
It's armor.
**[15:57] (Flashback) Kanade**
Armor?
**[15:58] (Flashback) Yukimura**
You've heard of the halo effect.
**[16:00] (Flashback) Yukimura**
If you wear a lab coat, even you will
look slightly more intelligent.
**[16:04] (Flashback) Kanade**
What's that supposed to mean?!
**[16:06] (Flashback) Yukimura**
*Do not forget.*
**[16:07] (Flashback) Yukimura**
*Dressed in a lab coat, a symbol of wisdom,*
**[16:11] (Flashback) Yukimura**
*you have spent your days in diligent
study as a member of the Ikeda Lab.*
**[16:16] (Flashback) Yukimura**
*And, you know more about your
research theme than anyone here.*
**[16:24] Kanade**
*Okay. Don't let yourself lose to them!*

**[16:55] Kanade**
First, if you'll please look at this photo.
**[17:00] (Flashback) Kanade**
A-Are you sure?
**[17:02] (Flashback) Kanade**
I can show this picture without any set-up?
**[17:04] (Flashback) Yukimura**
It makes no difference to me.
First, you need to astound them.
**[17:08] Kanade**
This is a picture of my two senpai from last month
when they went on an amusement park date.
**[17:14] Kanade**
They sincerely and wholeheartedly
wanted to enjoy their date,
**[17:17] Kanade**
so they calculated the most efficient way to
***SIGN*** Cosmo Land Park Map
**[17:20] Kanade**
visit all the rides at the park,
the optimal date course.
**[17:24] Kanade**
They utilized the traveling
salesman problem.
**[17:27] Kanade**
Visiting every single destination in
turn and returning to the start point.
**[17:30] Kanade**
The problem is calculating
the shortest route.
**[17:34] Kanade**
It's a quintessential optimization problem,
**[17:37] Kanade**
and many methods of solving
it have been proposed.
**[17:39] Student D**
Yeah. You use that for dates, right?
**[17:42] Student E**
No one uses it like that...
**[17:43] Kanade**
However, the date in question
was very complicated...
**[17:46] Kanade**
There were wait times for the rides...
***SIGN*** 120 minute wait
**[17:49] Kanade**
and their plans were thrown
into great disarray.
**[17:51] Kanade**
That's when they looked at
each destination again,
**[17:54] Kanade**
set up time slots for the wait times,
***SIGN*** Wait Times
***SIGN*** Time
***SIGN*** Magnum
Coaster
***SIGN*** Super

***SIGN*** Giant
Swing Pirates
***SIGN*** min
***SIGN*** min
***SIGN*** min
**[17:56] Kanade**
and used them to recalculate the
route with the shortest time.
**[18:00] Kanade**
A new optimization problem,
**[18:03] Kanade**
the "variable latency traveling salesman
problem." That is my proposal.

**[18:08] Kanade**
Using this problem, it's possible to
calculate an even more viable date course.
**[18:13] (Flashback) Kanade**
I really believe there are limitations
to using TSP to plan a date.
**[18:16] (Flashback) Kanade**
If you could at least add wait
times into the calculation...
**[18:19] (Flashback) Yukimura**
Then you should create that.
**[18:21] (Flashback) Kanade**
Huh?
**[18:23] crowd**
Wow...
**[18:24] crowd**
This seems like something you could
really use at an amusement park, doesn't it?
**[18:31] Kaku**
May I ask a question?
**[18:34] (Flashback) Kanade**
Aren't there any countermeasures
for questions?
**[18:37] (Flashback) Yukimura**
If you have time to think of such cheap tricks,
**[18:40] (Flashback) Yukimura**
then use that time to look
into the previous research.
**[18:42] (Flashback) Yukimura**
The professors aren't asking questions
to disparage the students.
**[18:47] (Flashback) Yukimura**
If you don't know something, say so.
**[18:50] (Flashback) Yukimura**
Answer what is asked with sincerity
and engage in discussion.
**[18:56] Kanade**
Please do.
**[18:57] Kaku**
Configuring the wait times at each location
**[19:01] Kaku**
requires all the wait times
to be confirmed in advance.
**[19:06] Kaku**
Is it possible to assemble that data?
**[19:09] Kanade**
Well...
**[19:11] KAnade**
As you say, it is difficult
to make perfect estimations.
**[19:16] Kanade**
However, in many cases, an amusement
park's daily wait time data is stored.
**[19:22] Kanade**
Using that as the foundation...
**[19:24] Kanade**
If it's sunny on a weekend...
***SIGN*** Magnum Coaster Wait Times

**[19:26] Kanade**
On a weekday, it'll be about this much...
**[19:27] Kanade**
Things like that...
**[19:31] Kaku**
Well, I suppose that's the
only thing you could do...
**[19:34] Kanou**
May I ask a question, as well?
**[19:37] Kanade**
Please do.
**[19:38] Kanou**
I do believe it is an interesting theme,
**[19:41] Kanou**
but was there no similar previous research?
**[19:44] Kanade**
Let's see...
**[19:46] Kanade**
In my research, I couldn't find any, but...
**[19:49] Kanou**
Really... Could there be one...
**[19:51] Kanade**
But, there was one...
**[19:53] Kanade**
that seemed similar when I read it.
**[19:55] Kanade**
The time dependent traveling
salesman problem.

***SIGN*** Which way
should I go?
**[19:59] Kanade**
In this problem, the travel time
from destination to destination
**[20:02] Kanade**
changes depending on the time.
**[20:04] Kanade**
It isn't the points that change,
**[20:06] Kanade**
it's the significance of the surroundings
that change in this type of problem.
**[20:09] Kanade**
Oh! But this is just within the bounds
of what I was able to investigate.
**[20:13] Kanade**
There may be similar research, but...
**[20:16] Kanade**
Could it be that you know
of similar research?
**[20:19] Kanade**
If you have, I'd love to—
**[20:21] Kanou**
Oh, no. It's nothing like that.
**[20:23] Kanou**
Kanade-kun, was it?
**[20:26] Kanou**
That's Ikeda's Lab for you.
**[20:28] Kanou**
It's only been four months since
you joined, and yet...
**[20:31] Kanou**
You've really done your research.
**[20:38] (Flashback) Yukiumra**
Read these immediately.
They are papers in your field.
**[20:41] (Flashback) Yukimura**
They will be of use one day.
**[20:43] Kanade**
Yes. A nagging senpai has
trained me very well.
**[20:49] Yukimura**
The "nagging" wasn't necessary.
**[20:53] Inukai**
I'm sorry!
**[20:55] Ikeda**
The exchange of opinions is
very important, however,
**[20:59] Ikeda**
calling a professor "baldy" isn't good.
**[21:03] Inukai**
I-I just got all fired up...
**[21:16] Kaku**
Inukai-kun, wasn't it?
**[21:23] Inukai**
Huh?
**[21:24] Kaku**
My, that was a wonderful debate, wasn't it?
**[21:27] Kaku**
It's been a long time
since I've been so excited.
**[21:31] Kaku**
I haven't had a student snap back at my
questions like that in quite some time.
**[21:36] Kaku**
It was very educational for me, as well.
**[21:39] Kaku**
I'm looking forward to
your next presentation.
**[21:44] Inukai**
Yessir!
**[21:47] Himuro**
Yukimura-kun...
**[21:49] Yukimura**

**[21:50] Yukimura**
It's good that Kanade's presentation
finished without any issues, don't you think?
**[21:54] Himuro**
