And so, this number is canceled out and—
Teacher.
In that case, wouldn't it be more efficient to use this formula?
My, Prince Cecil. No such theorem exists.
Indeed. I've just created it.
Cecil 10 Years Old
What? Your Highness is exceptional, but that isn't...
I-It works?!
But that means this is a new discovery in the world of mathematics!
By connecting the parts we were given, I believe it arises quite simply.
I-I'm going to go make a report to the society!
He's gone.
Well, it doesn't matter.
When I can understand a thing after hearing it once,
I can't say that hearing it over a prolonged period of time is beneficial.
Oh, how boring.
Prince Cecil!
I am a villainess!
My role is to rip Your Highness and the heroine away from each other,
and have you left in complete shock in the end!
Yes, that makes no sense at all.
An Observation Log of My Fiancée Who Calls Herself a Villainess
Chapter 1
An Observation Log of Meeting a Self-Proclaimed Villainess.
I am Cecil Glo Alphasta.
I am the First Prince of the Kingdom of Alphasta and its crown prince.
Today is the day that my fiancée,
Bertia Ibil Noches, daughter of a marquis,
and I first met face-to-face. However...
it seems that I'm not the only one who doesn't understand what she's saying.
Miss Bertia, standing and chatting isn't really the thing to do.
Would you like to have some tea while we talk?
What?
Y-Yes.
This is Zeno.
Zeno
He's my personal butler. Please look on him kindly.
Stare...
Is something wrong?
Prince Cecil, aren't you a little too composed for your age?
Is it possible that you're a reincarnation?
A reincarnation?
I was taught that this is how royals should behave themselves.
It's only natural.
No, it isn't!
If there was some other detached,
philosophical, ten-year-old prince, no one could stand it!
The voice inside your heart is spilling out, Zeno.
Well, then. Will you explain what you were saying before?
Of course!
I must have Your Highness understand everything
and become a person worthy of spurning me.
This may shock you, but I have memories of my past life.
In the land where I was born and raised, Japan,
there were stories I could watch with moving pictures that were like novels.
Japan Woman A Playing a Game
Cecil Glo Alphasta
These "otome games" were something I enjoyed immensely.
Hey, it's you.
"Hey, it's you."
Then, when I regained my memories,
that's when I realized..
That otome game had depicted this world.
That's why I know the whole scenario... the future.
Your Highness will fall in love with a noble's daughter, the Maiden of Destiny.
I, the villainess, will turn into a jealous demon and torment her horribly.
This will enrage Your Highness.
You'll break off our engagement, and my house will fall into ruin!
In short, getting the better of me allows the two of you to find happiness together!
Though my fate is to fall, I will do it beautifully!
I will become a first-rate flower of evil!
Before this, I've never once been unable to understand what someone was saying.
Though, to be honest, whether she has an overactive imagination,
or the power to predict the future, it doesn't matter to me.
In short, she's aiming to become a person who fits into this scenario of hers.
As long as it isn't something problematic for a future queen, I don't mind at all.
I was wondering, what exactly is this first-rate flower of evil you mentioned?
Strong, noble, and beautiful!
Though her path may lead to destruction, she treads it without hesitation!
That's the kind of woman I'm talking about!
Strong, noble...
and beautiful?
Oh, I slipped!
N-No, you have the wrong idea!
Bertia was always supposed to be someone who didn't really have a chance.
So, as a character, her appearance is questionable.
She sounds like a sad sort of person.
Are you all right with all of that?
I am not all right.
Everything I spoke of was the Bertia in the game.
I am... I am myself!
In my past life, I tended to hide in my own shell, but you were my support.
Prince Cecil, I wish for your happiness!
And that is why I will become an honest, righteous flower of evil!
An honest, righteous flower of evil?
I will improve myself and come again!
A pleasant day to you!
Bertia has run away
I wonder what all that was.
Your Highness, what will you do?
Well...
as far as becoming my fiancée,
she has none of the manners necessary to interact with royalty,
and I don't understand many of her words and actions.
And that is exactly what makes her so entertaining.
I will observe her for a while.
If it becomes necessary, I need only tame—
lead her down the correct path.
You seem like you're enjoying yourself.
This sense of unpredictability isn't bad at all.
Generally, if I try something, I can do it on my first attempt,
so, for me, the world is a tedious place.
I've rarely ever felt a sense of accomplishment.
In my eyes, the world has lost its color.
Which is why...
I hope you won't betray my expectations.
One Year Later
Your Highness, there is a report from that messenger.
Lady Bertia has secluded herself within her home for a year.
Surely it's cause for concern now.
I've been sending messengers to go and see how she's faring.
She's in exceedingly good spirits.
Then why has she shut herself away?
Zeno, you will understand once you see her.
She should make an appearance very soon.
A Few Days Later
It has been quite some time, Your Highness.
You don't know who I am, you say?
Bertia Ibil Noches!
Your Highness's fiancée!
Well, this is something. Her appearance has changed quite a bit.
It seems that those reports were true.
Just two more kilos!
Did you mistake me for someone else? You didn't recognize me, did you?
Ow!
THUMP
What sort of attitude is that to take toward the crown prince, Bertia?
What are you doing, Father?
Your Highness, please forgive my idiot daughter's rudeness.
Please, don't let it trouble you.
It's quite childlike and adorable, wouldn't you say?
Y-Your Highness... would you please say that one more time?
When you, um... said "adorable."
Bertia.
Don't let his appearance fool you. His Highness's eyes never smile, do they?
He doesn't have the emotions necessary to dote on cute things. He's too cold.
You will make do with my love-filled use of "adorable."
You're adorable!
I wonder if the marquis is aware that what he said was ruder than Miss Bertia.
Oh, Kuro!
I knew it. It is alive, isn't it?
I'm terribly sorry.
Ever since I took her in, she won't leave my side.
So I had her imitate a scarf and brought her with me.
Imitate.
It wasn't a successful imitation, but still, this is...
I thought it must be so.
If I keep quiet about it now, it'll make things more entertaining in the future.
Now, please have some sweets before the tea gets cold.
Thank you! I'll have some!
Diet.
This cake was made with a reduced amount of sugar.
I'm not particularly good with sweets, you see?
Reduced sugar! Cake!
Please, have some.
I thought she was aiming to become a strong, noble flower of evil, wasn't she?
I feel like she's heading in the opposite direction.
Well, shall we begin speaking of tomorrow?
Yes! At the party tomorrow, as a first-rate villainess,
I'll nobly fulfill my duty as Your Highness's partner!
Why is it, I wonder?
She meant to seem reliable, but now I feel anxious.
That's very reassuring.
But the fact that you're a villainess and that you have memories of a past life...
let's keep that a secret between just you and I.
Why?
Because the high society that we're about to enter into
is a world where you never know what may end up having a harmful result.
A flower of evil who leaves herself open to attack would seem inferior, no?
I-I see!
Defeating one's opponents in secret is first-rate,
while talking big and digging one's own grave is third-rate!
I completely understand!
I'm different from the Bertia in the game
because I will become a beautiful, noble flower of evil!
I'm so glad you understand.
Though I feel her understanding is slightly skewed.
Tomorrow is my eleventh birthday, and I'm happy to have you there celebrating it.
I'm also happy that I will be celebrating Your Highness's...
Eleven?
Your Highness is turning eleven years old?
That's right. You didn't know?
No, I knew. It's just...
Which means that on my next birthday, I'll turn ten.
Your Highness, my mother... my mother is going to die!
Your mother?
According to the scenario,
it will be from an epidemic that starts spreading in the summer.
Just before my tenth birthday, my mother will die.
An epidemic?
Apparently, a certain infectious disease evolves.
It takes time to find a method to treat it, and on top of that,
the herb needed for the medicine...
luona leaf, there won't be enough of it.
A great many people will lose their lives.
Luona leaf.
It's definitely a medicinal plant that is difficult to cultivate.
Father searches frantically for luona leaf, but he isn't able to obtain any.
In the end, he asks His Majesty to spare him some, but...
What you're speaking of happens a year from now, doesn't it?
If you prepare for it now, won't you be able to save your mother?
But, if I do that, the scenario will...
The scenario or your mother? Which is more important?
Of course my mother is!
But... but if the scenario gets twisted, Your Highness will...
Me?
Your Highness.
Here. Wipe your tears.
I'm your fiancé.
If you ever find yourself in trouble, let's think about what to do together.
One Year Later
Noches House
Your Highness is simply awful!
Honestly! Honestly! Oh, honestly, honestly, honestly!
P-Please, forgive me. That behavior was unbecoming of a lady.
No, I should be the one to apologize.
Have I done something to cause that charming face of yours to crumple?
Today is already my tenth birthday!
I wanted to develop more of a strategy against the epidemic...
but in your letters you only ever replied, "It's all right."
What was I supposed to do?
I'm sorry.
I didn't realize that you were feeling so distraught.
But everything really is all right. That's why I wrote that in my letters.
I desperately tried to collect luona leaf, but I don't have nearly enough.
And for some reason, when summer came, the disease didn't spread.
And my mother is in perfect health.
I just don't understand what's going on anymore!
Don't worry. The epidemic did begin, just as you said it would.
It's simply already died down.
So the infectious disease really did spread?
What?
I used your information to guess the disease and made medicine for it.
As soon as it began to spread, the patients received immediate treatment.
Huh?
What?!
W-Wait, Your Highness! What do you mean?
You're the only one allowed to treat me this way, Miss Bertia.
I understand. First, let's calm down a little.
How can I possibly stay calm? Hurry up and explain, please!
Let's take a little walk outside.
Now, let's go back to just after you spoke to me about your mother.
His Majesty seemed to be very pleased.
One Year Ago
The Royal Palace
He gave you permission to use the greenhouse right away.
Perhaps, with the worry of what to get his son as a birthday present gone,
he felt relieved.
And what will you do next?
First, the library.
I must look into luona leaf.
Some Time Later
It was so simple to successfully cultivate luona leaf.
A giant luona plant has grown.
Luona leaf grows this big? Was it Your Highness who grew this?
Since I have this, maybe I'll try making some medicine.
This is the discovery of the century!
To do that, I'll first have to identify the infectious disease.
It's magnificent!
I asked Miss Bertia about the characteristics of the disease...
Asked Questions at Noches House
My mother's disease?
I borrowed knowledge from experts in medicine and pharmacy...
Asked Questions at the Royal Palace
and I was able to identify the disease.
There's nothing left that I can teach you, Your Highness.
It's likely that the disease is a mutation of this one.
Read a Mountain of Books.
And so a remedy...
Performed a Number of Experiments
Easily Completed.
I've gone and done it.
You made it quite easily, didn't you?
Well, we don't know if it's effective or not.
There's no way to test it without someone stricken by the disease.
But if we truly want to be prepared, I'll have to make the adults take action.
I'll pretend that I just happened to take an interest in a certain disease,
and invite a doctor who is studying it to the palace as my teacher.
I'll passionately discuss infectious diseases.
I vehemently insist!
Then we'll discuss the possibility of a new strain and how to combat it.
I vehemently insist!
As a separate matter,
I'll tell him about the effects of the luona leaf I happen to be obsessed with,
A huge hint!
and speak quite passionately.
Cecil provided him with a big hint.
Then, I set it up so that the new disease strain would connect to the luona leaf.
If I can get him to come to the realization himself, then...
If it has such effects,
then it's likely to be useful in my colleague's research...
I'll tell them about it.
The effect was lackluster.
It's not in your colleague's research, but yours that it should prove useful.
Why is he unable to realize something so simple?
Your Highness, you seem to be fighting a difficult battle.
And you seem oddly happy, Zeno.
No, not especially.
Still, he is an excellent doctor.
I'm sure he'll realize eventually.
A Few Months Later
I vehemently insist!
Could it be...
wouldn't that luona leaf have some effect against the disease?
The doctors had a revelation.
Perhaps it would.
That took a long time.
That's how it happened.
After some time, the first patient with the disease was discovered,
and that same doctor gave her thorough medical treatment.
The truth is that when a patient really did appear, I was surprised.
Because it wasn't as if I completely believed Miss Bertia's story.
But I learned a lot.
The fact that I had difficulty guiding the doctor...
and the fact that I made Miss Bertia feel so anxious...
might be the result of my bad habits.
When I theorize, I understand too easily.
And I seem to have a tendency to omit explanations.
J-Just a moment, please.
So much of that seems strange.
Your Highness, why would you do all of that?
Why?
I have no intention of ignoring my fiancée when she appears so anxious.
B-But an eleven year old child could hardly do all of that!
I am the crown prince.
I can use the palace library,
and with my father's permission,
it's possible for me to call on brilliant experts for help.
R-Really?
No, of course not!
For a normal crown prince, it would be impossible!
That's amazing, Zeno!
You're so far away, and yet I can hear the voice of your heart.
Is it really possible for things to work out so conveniently?
I suppose I should expect it from the genius known as the Android Prince.
Android?
Please don't worry about the details.
If your mother is safe and the harm to the people was kept to a minimum,
then everything's fine, isn't it?
Y-Yes, you're right!
After all, everyone has evaded the evil clutches of the epidemic.
This is for the best!
Yes. I see you've given up on thinking about it.
Oh, that's right. Aside from the official gift,
I have something else I'd like to give you, Miss Bertia.
You still have some other surprise for me?!
It's from me personally. A handmade birthday present.
Oh, it's lovely!
The truth is that this is actually a universal antidote.
Wh-What?
A universal antidote?
While I was researching all sorts of things,
I found an interesting book in the palace library.
What's that?
A seam?
It moved.
Using the knowledge I gained from there, I tried making that.
Since you'll become my wife, it's possible that your life will be threatened.
I thought it could be a protective charm.
Yes, it suits you very well.
Th-Thank you... very much.
Prince Cecil.
I, Bertia Ibil Noches, swear upon this necklace!
In order to repay the debt of gratitude I owe you,
I will make sure to thoroughly rectify the scenario...
and I will show you what a magnificent villainess I can become!
First, my father, who should have started down the path of evil...
I'll have him turn into a proper villain!
No, that's really all right.
Losing a chancellor would cause problems, after all.
I will make sure that Your Highness and the heroine get your happy ending!
Yes. It seems she isn't listening to most of what I'm saying.
Well, that's all right. It does seem entertaining, after all.
I'll give it my very best!
Bertia has renewed her resolution.
